The deep dive

Every organization has threat intelligence

Dan Sherry and Grace Chi of Pulsedive: a free tier anyone can use without an account, a ladder from free to Pro to data to a private platform, feeds by the dozens, if not thousands, that nobody can benchmark, sharing that stays opt-in, feedback that shapes a paid product, integrations users build themselves, a pandemic that froze budgets for six months, and the elevator test.

Episode 12 of The Security Podcast of Silicon Valley aired on January 20, 2022, with Jon McLachlan hosting. The guests were Dan Sherry, founder and CEO of Pulsedive, and Grace Chi, its cofounder and COO (Podbean, Apple Podcasts, Spotify). The episode is called “Founder Dan Sherry and Co-Founder Grace Chi deep dive into Pulsedive, Demystifying Threat Intelligence.”

Pulsedive is a bootstrapped cyber threat intelligence startup. The line that sums up the episode:

“every organization has threat intelligence, even if they don’t have threat intelligence.”

Grace Chi, at 16:19

This page follows the conversation in order: a section for each part of it, fourteen figures, eight clips from the tape, a talk of Grace’s on video, the full transcript, and five tools: a quiz, a scorecard for where your threat intelligence lives, a calculator for what false positives cost, a timeline, and a to-do list. Where the decodes of the tape disagree on a word, the transcript puts its best guess in brackets, and the page doesn’t quote or retell those words.

Two founders, two paths

Jon opened with the founders’ bios. Dan has years of incident response, security engineering and security operations across government and Fortune 500 financial services, knows the struggle of filtering noise out of open source threat intelligence, and sees Pulsedive as the first step to solving that problem. Pulsedive’s company page describes Dan’s background in the same words (Pulsedive). Dan’s LinkedIn lists the path: security analyst and engineer roles at ADP from June 2013, a cyber security analyst role at the Federal Reserve Bank of New York from September 2016, and Pulsedive from August 2017 (LinkedIn).

Grace works closely with defense, security and cyber threat intelligence teams on integrated intelligence capabilities and programs, as Jon read it. Grace’s LinkedIn lists marketing and product marketing roles before Pulsedive, including product marketing for a supply chain technology company and a stealth managed detection and response startup, and the cofounder and COO role since August 2019 (LinkedIn).

Platform and data

Grace’s short version: Pulsedive is a cyber threat intelligence startup that offers both a platform and data. Most of its users are blue team practitioners, in security operations centers, incident response and threat hunting. They work on every continent except Antarctica, in small and large teams, at security vendors and service providers as well as institutions and enterprises.

The product is enrichment: external scanning and scoring of indicators of compromise, correlated with threats and threat actors. Users get transparent, raw but structured data they can pivot on and bring into their own investigation, research and analysis.

“we try to be very versatile technically and very intuitive for the UI and the analyst.”

Grace Chi, at 3:26

An indicator of compromise is a technical artifact, such as a suspicious IP address, a hash of a malware file or a malicious domain, that suggests an attack is coming, under way or already happened (Wikipedia).

By hand, or by API

Some users work by hand, on research shaped by their own expertise and their own threat environment. Others automate. Because the security space changes all the time, Pulsedive plugs into other tools through an API or a feed, so its intelligence and enrichment go wherever a team needs them.

A ladder of products

Jon asked whether Pulsedive fingerprints or scans the network for traffic known to have bad intent. Grace liked the word mal-intent, and walked through the portfolio.

At the bottom is a freemium community tier. Anyone can use it without registering, run passive or active scans, pull back data and never make an account, and that’s on purpose. Those users are often getting started in threat intelligence, or work in IT and also wear the security hat, with no budget.

A step up, teams pay for the commercial API or a feed license. That’s where they automate enrichment: the IPs, domains and URLs coming through their tools go to Pulsedive for a scan, the data and a score come back, and incoming alerts get enriched in bulk. At the top, an enterprise tier gives an organization its own private instance of Pulsedive, where it picks the threats that matter to it and configures its own internal and external data sources.

Pulsedive’s site lists the same ladder today: search for anyone, a free account to submit and comment, Pro for non-commercial use at $29 a month, the API and Feed for commercial use, with the feed in CSV or STIX/TAXII 2.1, and a dedicated, cloud-hosted Enterprise TIP, or threat intelligence platform (Pulsedive).

Four cards, numbered. 1, free community tier: anyone, without registering, passive or active scans, data back, no account. 2, Pro: for an individual, on the site today $29 a month, for non-commercial use. 3, API and feed: commercial, automated enrichment and bulk enrichment of alerts, and the feed comes in CSV or STIX/TAXII 2.1. Filled, 4, Enterprise: a private instance, with the threats that matter to you and your own internal and external data sources. Below: some users climb the ladder, and Grace counted that as validation of how Pulsedive sits in the market. Then: "there's free and then there's individual pro and then there's data subscriptions and then there's a full platform." Grace, at 38:29

Pulsedive’s FAQ explains the two kinds of scan. Passive scans look up WHOIS, DNS and metadata without touching the target. Active scans reach out to the target with a headless browser and collect HTTP requests, TLS certificate data and cookies, which tells you more but makes more noise (Pulsedive).

Two cards. Passive scan: looks up WHOIS, DNS and metadata, with no direct contact with the target. Filled, active scan: reaches out to the target with a headless browser, collects HTTP requests, TLS certificate data and cookies, with more detail and more noise. Below: scans run from hardened, rotating proxies. On the episode, Grace said anyone can run either kind on the free tier, without an account.

A business that does important work

Jon asked what shaped the founders’ values. Dan’s story starts in college, around the time Facebook got huge and The Social Network came out. Dan wanted to start a company, and built apps in college to try to build a business around while studying cybersecurity. The 2010 film, about the founding of Facebook, opened in the U.S. on October 1, 2010 (Wikipedia).

The security job itself turned out to be fulfilling. Cybersecurity offered both a business to build and work that mattered, and the problem showed up on the job:

“we’re collecting a bunch of data. How do we leverage all that so we’re not hunting for the same things that people already know about?”

Dan Sherry, at 7:35

Dan started in the industry in 2013, as it began to grow exponentially. Threat hunting was still relatively new.

Out of right field

Grace described the pairing. Dan has the traditional path, years of security engineering, incident response and threat intelligence work, and built the product Dan wanted to use. Grace came in from completely out of right field. Marketing was a way to learn how businesses grow, working closely with a lot of leadership. Grace sees outside perspectives as a way to enrich the whole industry. In security, Grace has seen technology pushed without the operational work or the skilled staff to run it:

“Technology is so important, but it really fits within processes and people.”

Grace Chi, at 10:58

Jon said the two complement each other: a team of clones preaches to the choir, and a diverse team makes a startup more resilient.

Fix the foundation

Jon asked for one truth most people miss. Dan’s answer: the industry keeps building the newest technology, but hasn’t nailed the foundation. There’s room to take a step back and smooth over what a lot of small businesses struggle with. The attention goes to new ideas that haven’t been tried, but there’s a lot to do in changing or improving existing ones. Dan remembered reading research that the most successful companies iterate on earlier ideas.

Jon put it as making existing ideas more accessible to a wider audience. Dan added that iterating is an easier way into a market, because customers already know what that kind of product does, and Jon added that you’re doing the manual work of stitching it together for them.

Two cards. Dashed, where the industry looks: the newest, latest and greatest technology, and new ideas that haven't been tried. Filled, where Dan looks: the foundation, take a step back, smooth over what small businesses struggle with, and improve existing ideas. Below: iterating is an easier way into a market, because customers already know what that kind of product does. Jon added that you do the manual work of stitching it together for them. Then: "the most successful companies are actually iterations over previous ideas versus ideas that are completely new." Dan, at 12:40

Problems that should be solved by now

The view came from meetups, talking with engineers and responders stuck on the same problems, the kind that make you ask why they haven’t been solved. New companies kept coming out, and Dan asked why more people weren’t addressing the problems of organizations that aren’t as mature or have smaller budgets. The frustration was shared by engineers trying to automate and support vendor solutions, and by responders trying to tell whether something is a false positive.

Jon tied it to the cloud. Everyone with a cloud environment is responsible for protecting it, and when security is priced out of reach or too complex for small businesses and startups, the gaps grow. A free tier invites everyone to the table.

Every organization has threat intelligence

Grace’s truth was about sharing. When threat intelligence hit the market, everyone wanted feeds, and feeds came out by the dozens, if not thousands:

“no one can really truly benchmark the quality, the efficacy, the relevancy of various lists of IOCs.”

Grace Chi, at 16:09

The result is intelligence that lives in emails and in blog posts that link to each other, and that isn’t great. Places where users share intelligence, add commentary and submit things for other users mean that a small business with few resources isn’t fighting alone. Trust groups, coalitions and public-private partnerships exist, but they’re disjointed and hard to keep up with, and Pulsedive aims to be one niche of that space.

Cyber threat intelligence is the part of cybersecurity that collects, analyzes and shares information about potential or existing threats (Wikipedia).

Then: "every organization has threat intelligence, even if they don't have threat intelligence." Grace, at 16:19

Opt in, never forced

Jon asked how Pulsedive gets people to give back. Grace’s first answer was free things, giving value before asking for anything. Then Grace named a second challenge: you want people to contribute, and you also want to protect them. Contributors don’t have to say who they are, and a username is enough. Anyone can do research without submitting it to the community when the work is sensitive.

“you opt in to share”

Grace Chi, at 18:13

Free, without an account

Grace asked Dan for the turning point. Pulsedive started out as an enterprise platform, built to compete with the other platforms coming out at the time. To show people what it did, Dan put data in it, and found that people didn’t want to go through a login screen to discover something they didn’t know they needed:

“So I started making a lot of stuff accessible for free without an account, to try and lower the barrier to entry.”

Dan Sherry, at 19:04

More people used the platform and the data, and some were willing to pay for the data. So Pulsedive discontinued the enterprise version for a while. By the time of the episode, the value had been proven, and people wanted that value within their own environment.

Contributors want you to stick around

Dan said people are surprisingly willing to help smaller organizations and put their data out there. There are so many open source projects, and a lot of it is pretty disjointed. Contributors want reassurance: that the data will be accessible to other organizations, that you can support their data sets, that the company will last, and that you’ll represent their data accurately, so it gets used the way it’s meant to be.

Feedback counts too

Grace widened what contributing means. Sharing data means submitting indicators such as IPs and URLs, linking them to threats and adding comments. Feedback counts too: user input, complaints, and what people love. The research for Pro, a paid product launched a year before the episode, surprised Grace:

“I did not expect people to want to help”

Grace Chi, at 21:45

Grace asked about 30 people, users and non-users, some known and some not, and all of them were willing to get on the phone. Even people who weren’t fans of the community platform supported the vision. The input made the product better, and Grace credited it for a great Black Friday. Pulsedive’s Black Friday 2021 deal took 50% off Pro and API plans for up to 12 months, through November 30, 2021 (Pulsedive).

Two cards. Sharing data: submitting indicators such as IPs and URLs, linking them to threats, and adding comments. Filled, feedback: user input, complaints and what people love, and about 30 people got on a call for the Pro research. Then what contributors need. Protection: a username is enough, and research can stay private when it's sensitive. Reassurance: data that stays accessible to other organizations, support for their data sets, an accurate picture of their data, and a company that will last. Then: "I did not expect people to want to help" Grace, at 21:45
Two ways the community contributes. Source: the episode.

Community, or commodity

Jon summed it up: if you give, the community gives back. Jon recalled hearing, probably from a venture capitalist, that without a community, you become commoditized, like any other product:

“a Kleenex is a Kleenex, no matter what the brand is.”

Jon McLachlan, at 22:39

With a community around the people struggling with the same problems, the brand lasts. Grace added that the founders take part in that community too, with a collateral benefit. The founders talk to thousands of threat intelligence teams, have helped people land jobs by knowing both who’s hiring and who’s looking, and advocate for diverse and new talent coming into the field. To build a great product you have to understand the market, and to understand the market you have to take part in it. Dan agreed: you need the community, and you need to be part of it.

Pulsedive signed the Respect in Security pledge in July 2021, a commitment to a workplace free from abuse and harassment (Pulsedive). On August 12, 2021, The Diana Initiative posted Grace’s talk on threat intelligence careers from its 2021 virtual conference. The talk introduces the basics of threat intelligence and how to get a first role and advance a career, and debunks a few myths about the job (Pulsedive).

Quarterly reviews and a first sale

Jon asked about the best day. Grace pointed to the quarterly business reviews: a grind of wading through data, but in a startup where every day is chaos and progress is hard to see, measuring the change quarter over quarter shows how far you’ve come. Who signs up, how they use the product, what worked and what surprised you. Taking the time to look back and plan forward keeps the founders aligned.

For Dan, it’s seeing the company grow from a vision worked on during nights and weekends. Grace noted that it’s nights and weekends now, and during the day too. Dan’s first sale took about a year, and it showed this was a viable business model. Building the product came first, then feedback, and making sure Pulsedive offered enough value that people could justify a line item in a budget for it.

The invoice nobody expected

During that first year, an unexpected buyer got in touch, interested in the feed. Dan assumed one of the lower tiers, and they wanted the highest one, with an invoice. Dan called that year a roller coaster.

Grace said it happens all the time, because Pulsedive has no outbound sales process and does no paid advertising. People use what they want, and some come back asking for an invoice for a package. When Grace asks how they heard about Pulsedive, the answers are grassroots: they used it before and liked the interface or how easily the API set up, they changed jobs and brought it along, a team’s internal wiki lists it for enrichment and research, or someone asked in a Slack or Discord group and got a warm referral.

Integrations users build

Jon raised the investor question: would Pulsedive raise money and go for the hockey stick? Grace mentioned the hockey stick every startup says it can do, then added something the community gives Pulsedive:

“integrations are the name of the game.”

Grace Chi, at 30:17

Users ask other tools for a Pulsedive integration, or build their own community marketplace integration. That gives Pulsedive development capability that didn’t come from its own team, and new customers find Pulsedive through those integrations. Pulsedive thanks the builders with deals and discounts. When Jon brought up an open source GitHub, Grace pointed to the API documentation: Dan answers a few quick questions, and an integration appears. The best ones, for Grace, are integrations nobody knew about until they were published and people showed up using them.

Pulsedive’s home page now lists integrations such as Cortex XSOAR, Swimlane, IntelOwl, Microsoft’s msticpy, Polarity and a Microsoft Sentinel guide for importing the feed (Pulsedive). A threat intelligence platform imports threat data from many sources and formats, correlates it, and exports it into an organization’s existing security systems (Wikipedia).

Funkiness, and users nobody planned for

Good days come from users too. After Pro launched, users came back saying they’d found funkiness and pivoted on it, like the single security person whose detection, made with Pulsedive’s help, protected the company. The team keeps a private channel in Slack for that kind of feedback, to stay motivated.

Then there are super users from outside the usual use cases: red teamers doing reconnaissance, people evaluating vendors, and technical due diligence. They ask for features, and their answers to why point Pulsedive toward new markets to test. Asked for the most surprising ask, Grace named users from anti-money laundering, fraud prevention and detection, and third parties evaluating tools.

Red teams use it too

Jon asked whether a red team user makes the founders suspicious, in case someone checks whether an attack will be detectable. Dan said a lot of red teams use Pulsedive for threat intelligence background and on penetration tests. The conversation called it an initial scan, a baseline of where they start. Dan added that Pulsedive can show whether a company’s assets have turned up as indicators, on its feeds or in submissions.

Six months of a bad day

The worst day, for Grace, was a slow dread when the pandemic hit. Pulsedive saw no dip, and probably an increase in free users. But from the end of the first quarter of 2020 through the end of the second, budgets froze, nobody was hiring, and everyone hunkered down. The founders counted the runway and the expenses to cut. When it lifted, the third and fourth quarters recovered, cybersecurity was booming, and it was a major relief.

“So that’s really six months of a low humming bad day.”

Grace Chi, at 35:23

Jon heard the same from many startups about 2020. Dan named the same stretch, and the first year. Dan shared a line that resonated: failure is the default, and resilience, fighting that failure every day, is what gets you somewhere better.

A timeline. End of the first quarter of 2020, filled: budgets freeze, purchases on hold, nobody hiring, everyone hunkering down. Through the second quarter of 2020, filled: counting the runway, the founders count the runway and the expenses to cut, so Pulsedive can last. Third and fourth quarters of 2020: recovery, cybersecurity is booming, and it's a major relief. Below: users held up through it, no dip, and probably an increase in free users. Then: "So that's really six months of a low humming bad day." Grace, at 35:23

The next rung

Jon asked what the next milestone looks like. In the short term, Grace said, it’s keeping customers, upselling them, and the referrals that follow. Users already climb the ladder:

“there’s free and then there’s individual pro and then there’s data subscriptions and then there’s a full platform.”

Grace Chi, at 38:29

Grace also wanted Pulsedive to use its research, data and communities to contribute to the industry more intentionally, with enterprise users, communities and programs. Further out, and not committed or scheduled, was a community function: sharing intelligence with specific user groups or trust groups. Dan added the hope that people would publish their research and their own feeds there, and contribute in a more automated way.

The elevator test

Jon offered a test of success: two engineers in an elevator arguing over the best threat intelligence data, until one says to use Pulsedive and be done with it. Grace promised to report back when it happens, and told a story that came close. At the final BSides DC before COVID canceled the BSides conferences, Pulsedive showed up on screen in research by a speaker the founders didn’t know. On forums, people recommend Pulsedive to each other: the online elevator.

Grace said Dan keeps a low profile and doesn’t always see how much people admire the work. Users are surprised Dan built the whole thing with native development, without pre-built tools or frameworks. They assume Pulsedive is bigger and funded:

“we want to keep punching above our weight class.”

Grace Chi, at 43:03

Dan, with no full marketing team behind the company, credited Grace for much of that impression. Grace said it’s not supposed to be an illusion.

Marketing that reflects reality

Grace’s last point was that marketing gets a bad rap. The discipline Grace enjoys is finding out what’s authentic about a product, why users like it and want to talk about it, and applying that without forcing it. Pulsedive’s sales approach is consultative: it puts itself out there, educates, and keeps a presence that reflects the reality. For Grace, doing that for a community that cheers Pulsedive on is a 180 from past jobs.

Jon closed with thanks and an invitation to come back. Grace’s idea for next time: bring on a user, and let someone other than the founders do the talking.

What happened after the tape

A sharing report, eight days later. On January 28, 2022, Pulsedive published “Is Sharing Caring?”, a report on current threat intelligence networking practices, results and attitudes. It asks how one-to-one messages compare with invite-only Discords, paid memberships and Twitter, which ones helped detect an attack or fix it, and about raw data versus finished intelligence (Pulsedive).

Pulsedive 5 added MITRE ATT&CK. On February 20, 2022, Pulsedive 5 brought ATT&CK data to its threats, STIX over TAXII for paid products, and a rebuilt Explore (Pulsedive). ATT&CK is a guideline for classifying and describing cyberattacks and intrusions, created by MITRE and released in 2013. Every technique has an ID, such as T1566 for phishing (Wikipedia).

Enterprise came back as a product. On August 12, 2022, Pulsedive launched Pulsedive Enterprise, a centralized, private platform with collaborative curation and integration. The announcement put it as a threat intelligence platform “that doesn’t break the bank,” and said tens of thousands of practitioners rely on Pulsedive each month (Pulsedive).

Pulsedive 6 added bulk analysis. On November 22, 2022, Pulsedive 6 added Analyze, for parsing, processing and exporting indicators in bulk (Pulsedive). The 2022 year in review counted Pulsedive 5.0, 5.1, 6.0 and the Enterprise TIP (Pulsedive).

Docs got their own site. On March 30, 2026, Pulsedive launched docs.pulsedive.com, with a complete API reference (Pulsedive).

Where does your threat intelligence live?

Eight questions on whether your threat intelligence is more than emails and blog posts, built from the episode. Each tip links the section behind it.

Scorecard · eight questions

Where does your threat intelligence live?

Answer for your team as it works today. If two answers fit, pick the lower one.

  1. Where does your threat intelligence live today?

    • In emails and bookmarked blog posts
    • In a feed or a shared doc nobody vets
    • In a platform or pipeline the team can query

    Intelligence that lives in emails and blog posts isn't great. See Every organization has threat intelligence.

  2. Before you act on an indicator from a feed, do you check whether it's a false positive?

    • No, we act on the feed
    • Sometimes, by hand
    • Always, with enrichment and a score

    Responders struggle to tell a false positive from a real threat. See Problems that should be solved by now.

  3. Are alerts from your SIEM enriched before an analyst looks at them?

    • No
    • Some of them
    • Yes, through an API or a SOAR workflow

    Bulk enrichment is a step up the ladder. See A ladder of products.

  4. Do you know which threats matter to your organization?

    • No
    • Roughly
    • Yes, and we track them

    At the top of the ladder, a team configures the threats that matter to it. See A ladder of products.

  5. Do you share what you find with peers or a trust group?

    • Never
    • Informally, now and then
    • Yes, through a trust group or a platform, on our terms

    Sharing works when it's opt-in. See Opt in, never forced.

  6. Can your analysts research a sensitive indicator without exposing it?

    • No
    • Not sure
    • Yes

    Research doesn't have to mean submitting. See Opt in, never forced.

  7. Do your security tools pass data to each other?

    • Rarely
    • A few of them
    • Yes, most of them

    Integrations decide what a tool is worth. See Integrations users build.

  8. Do you watch for your own assets turning up as indicators?

    • No
    • After an incident
    • Yes, as a routine

    Red teams check that baseline first. See Red teams use it too.

Intel in the inbox

Your threat intelligence lives in email and bookmarks. Start by vetting the feeds you act on, and enrich alerts before anyone blocks.

Getting there

The pieces exist, but they don't talk. Automate enrichment, and decide which threats matter to you.

Intelligence that runs

Your intelligence is vetted, enriched and shared on your terms. Keep the integrations current, and watch for your own assets.

What do false positives cost?

Dan named a frustration responders share: working out whether something is a false positive. This calculator puts a monthly number on the time it takes.

Calculator

What do false positives cost?

Four numbers: alerts a day, the share that turn out to be false positives, minutes to dismiss one, and what an analyst hour costs you.

$18,000a month on false positives
8.0hours a day
240hours a month
1.5analysts' time

At 150 alerts a day with 40% false positives, dismissing them takes 8.0 hours a day, 240 hours a month. At $75 an hour, that's $18,000 a month, about 1.5 analysts' time.

The calculator counts 30 days a month, since alerts don't stop on weekends, and 160 working hours for an analyst's month. The default numbers are placeholders, yours to change. Dan and Grace gave no figures for these on the tape.

What to do this week

Five things, in the order of the episode.

  1. Find where your intelligence lives. List the feeds, emails and blog posts your team acts on, as in Every organization has threat intelligence.
  2. Vet a feed before blocking. Check a sample for false positives, and run your numbers through the calculator.
  3. Enrich alerts before anyone looks. Wire enrichment into the tools your alerts come through, as in A ladder of products.
  4. Share on your terms. Join a trust group, and decide what stays private, as in Opt in, never forced. The scorecard shows where else to look.
  5. Get help with it. Our 24/7 Monitoring & Response team watches your alerts and sorts the real ones from the noise, and the AI-Accelerated Cloud Detection & Response Program investigates cloud alerts in minutes. Penetration Testing shows the baseline an attacker sees first, and vCISO Services gives you a security leader to set priorities. If you want to talk it through, book 15 minutes with us.

Key takeaways

  1. Every organization has threat intelligence

    Feeds came out by the dozens, if not thousands, and nobody can benchmark their quality, efficacy or relevancy. Intelligence that lives in emails and blog posts isn't great. Places to share it, comment on it and submit to other users help small teams stop fighting alone.

  2. Free, without an account

    Pulsedive began as an enterprise platform. People didn't want to sign in before they knew they needed it, so Dan made a lot of it free without an account. More people used the platform and the data, and some paid for the data.

  3. Build a ladder of products

    A freemium community tier anyone can use, the commercial API and feed licenses for automated enrichment, and an enterprise tier that is a private instance. Some users climb from free to Pro to data subscriptions to the full platform.

  4. Keep sharing opt-in

    Contributors can stay anonymous or use a username, and can research a sensitive indicator without submitting it. You opt in to share, and nobody is forced to.

  5. Contributors want to know you'll last

    People will share data with a small company when it stays accessible to other organizations, when you can support their data sets, when you represent the data accurately, and when the company will last.

  6. Feedback is a contribution too

    For the Pro research, about 30 people got on a call, including some who weren't fans of the free platform. Their input made the paid product better.

  7. Let users build the integrations

    Users ask other tools for a Pulsedive integration or build one for a community marketplace, from the API documentation. New customers then find Pulsedive through those integrations.

  8. A bad day can last six months

    From the end of the first quarter of 2020 to the end of the second, budgets froze and nobody was hiring. The founders counted the runway and the expenses to cut, and the second half of the year recovered.

Jon McLachlan

Welcome everyone to the Security Podcast of Silicon Valley. I am here today with two very special guests, Dan Sherry and Grace Chi. Dan Sherry, he is the founder and CEO of Pulsedive, a security startup. Dan has years of experience doing incident response, security engineering, and security operations across both government and Fortune 500 financial services. He is all too familiar with the struggles of filtering noise from open source threat intelligence and sees Pulsedive as the first step to solving this problem. And Grace is co-founder and COO of Pulsedive. Grace works closely with defense, security, and in particular cyber threat intelligence teams to support and the development of integrated intelligence capabilities and programs. In addition to enabling the growth of CTI teams all over the world, Grace is an avid watercolorist on the weekends and a hyper-serious cooperative board gamer. What's your favorite board game?

Grace Chi

I have many, but the more stressful and the bigger headaches it gives me, the more I like it. So XCOM has been one of my favorites. Not the video game, the board game.

Jon McLachlan

That's awesome. That's, that sounds really stressful, actually.

Grace Chi

There's timers that range from like five to 15 seconds to do a bunch of tasks, and everybody is like contingent on each other because you have a budget, you have a military, and you're fighting aliens who are invading the world and descending upon you. There's like a tense music background that plays too. And it is like, why do I do this to myself? But it's also so much fun. And you still feel competitive because you have this shared enemy. Unlike cooperative games, where sometimes people talk too much, you don't have that time. You just have to make decisions and move forward. So it's like being in a startup.

Jon McLachlan

I'm super happy that you have a decompression mechanism that works best for you. And I might pass on any board game invitations, but no, she comes from a deeply unconventional and [interdisciplinary] background, including academic studies in neuropsychology, product marketing roles, and a lifelong affinity for mixed media and visual arts. Grace draws on her multidisciplinary love of learning to enrich her work and place in the cybersecurity community. Welcome. Welcome to the show, guys. Great to have you back.

Dan Sherry

Jon McLachlan

Would you like to share a little bit about what Pulsedive is and the problem space?

Grace Chi

In short, Pulsedive, we are a cyber threat intelligence startup. We offer both platform and data, and our users are vast majority like blue team defensive security, security operations center, incident response, threat hunting type practitioners in the cyberspace. But it is global, you know, every continent except Antarctica right now, and teams small and large, both within the dedicated cyber services and vendor space, as well as institutions and enterprises. What we offer is enrichment, kind of external scanning and scoring of various indicators of compromise. And then we correlate all that within different threats, different threat actors, and allow our users to really access like transparent, raw, but structured data, pivot, and bring that in so that it helps them in their investigation, research, and analysis in producing finished intelligence. One major component that we have as well is that we try to be very versatile technically and very intuitive for the UI and the analyst. So while we have users who are engaging in a more manual way or conducting very sophisticated research based on their expertise and their understanding of their threat environment, we also allow for a ton of automation and interoperability across other tools and solutions, because the security space changes all the time. So that you can really plug and play Pulsedive through API, through feed, and get our intelligence and our enrichment however you need it.

Jon McLachlan

No, that sounds very powerful, especially the opportunity to automate a lot of those processes. So as a quick example of how you might help, I know one of the huge challenges that folks face is just making sure that those layers of security that we set up don't allow for bad actors into our cloud environments or even our data centers if you're on-prem. So Pulsedive essentially, it fingerprints or scans the network for the traffic that's known to have mal-intentions. Is that

Grace Chi

Mal-intent. I like that. Yeah. So we offer a portfolio of products and offerings. So like at the most basic level, we have a freemium community tier. Anyone can use it. You don't even have to register. Like you can go in and conduct some passive or active scans, pull back data, and then never even have an account with us. And we do that very intentionally. Those users are typically who are getting started in threat intelligence. Oftentimes we have a lot of grateful users who are IT, but also have to wear the security hat, but they have no budget, they have no resources, and they need to do some manual research and triage based on their team needs, and they're trying to grow. At a more mature level, where you might be paying for the commercial API or the feed licenses with Pulsedive, that's when you can automate enrichment based on things coming from your [SIEM] or building into a workflow for your [SOAR]. So there's like IPs, domains, URLs that are coming through. You push it to Pulsedive, scan, pull all that data back, take actions, look at the score, you know, whatever that is, where you can bulk enrich alerts that come in as well. And then at the highest level, too, we offer an enterprise tier where you get to configure really your version of Pulsedive. It is your instance. It is private to everyone except your organization. You get to really then look at what threats matter to you, configure your own sources of data, internal and external, and then use Pulsedive as that like data analytics and threat intelligence database layer to then operate and have that feed into your integrated program.

Jon McLachlan

Yeah, that's really important stuff. And a complex space, keeping our bad actors out of our cloud environments or our on-prem, especially with that enterprise-grade offering that you have. It sounds like it fits the bill really nicely. So being in the security space, oftentimes I find, especially with founders, that goes, it ties into something maybe from childhood that really shaped who you are, how you see the world, and giving back to the security community in such a concrete way, especially with that free tier. It sounds like a great starting point for a lot of folks. But maybe there's a story or something that you'd like to share that really speaks to what gave you maybe some of these values to look at this difficult problem and take a lot of time out of your life to help solve it and build a more secure future for everyone.

Dan Sherry

Yeah, I mean, I think like when I was in college, that was around the time that like Facebook was like getting huge and when The Social Network came out. And so for a long time I wanted to, I knew I wanted to start a company and try to be one of those overnight founders. And so I'd have like these apps that I would make in college to try and build a business around while I was studying cybersecurity. When it started working, the job itself was really fulfilling. So I knew I kind of wanted to do something within cybersecurity, because it was not only the opportunity to build a business around that, but also something that actually did important work. And so when I was working, I mean, that was kind of when I ran into the problem of like, okay, we're collecting a bunch of data. How do we leverage all that so we're not hunting for the same things that people already know about? And so that problem was, I mean, it was like the perfect candidate to build a business around that. It was something I was really passionate about. I really like building things that help other people and make their jobs and lives easier. And so that's kind of how Pulsedive was formed.

Jon McLachlan

No, that's spectacular. Really awesome. So your focus and your passion really zoomed in on security and then how to use it to help people.

Dan Sherry

Yeah, yeah. Yeah, I mean, I was lucky because the things I were passionate about coincided with like a booming industry. So when I first started working in the industry, it was like 2013. So that was really when it was starting to grow exponentially. And then over the past decade, the industry really exploded. Like threat hunting was relatively like a new field, for example. So yeah, I was lucky to be like on the [cusp] of that.

Jon McLachlan

That's awesome. And Grace, do you have any childhood experiences that, it sounds like you're a very diverse background?

Grace Chi

Yeah, so like my childhood, like I, one thing that I think is really fun about [Pulsedive] is Dan has the traditional like security engineering, incident response, like working on threat intelligence as a practitioner for multiple years, built the product, right, that he wanted to use. And then like I come in as this [complementary], completely out of the like right field person. But that's been something that's been building my whole life. Like when I was young, and a lot of times I feel like in the American education system and just in general, like it's easy to try to box yourself into one role or do one thing, but I was just full of these like weird dichotomies where I was like, I don't fit in, I'm okay with it. But like, for example, I was like, I got like most artistic in high school, like in the yearbook. But then when I went to art school, like, I hate it here. I don't want to do this. And usually if you do art, you want to get a career in art. Okay. And then I loved academia. So when I was in college, I took on these double majors that were teaching me how to think for the sake of thinking, not going for the more traditional, like, what job do I want with this major? But then at the same time, like, I love business. And I also love volunteering and giving things back to the community, but then also growing a business and making money and commercializing, which is why I ended up in marketing, because this is a great way to balance and learn about how businesses grow and work directly with a lot of leadership, because it's so critical. And so my entire life, I would find these weird opportunities, not because I had applied to the traditional openings or whatever, but [I'd walk] into a museum and be like, I want to volunteer here just because, I don't know, I like art history, I'm studying art history. And then that would turn into a job. Or I would like tutor, or I would volunteer at Chinese school, for example. And then the parents would come to me and be like, can you be a private tutor? And I'm like, oh, okay. So my whole life, I just saw that there was a lot of opportunities and hidden places, and that they don't have to fit within what you've been necessarily building your whole career or persona out to be. And I think that's why I love being in cyber, because I don't have that traditional background that's so critical, but that there's so much that can be applied and help enrich like the entire community, the entire industry with outside perspectives. And that's thinking about it from a marketing perspective, thinking about it from a human perspective. Technology is so important, but it really fits within processes and people. And I think sometimes in the past, security, like they push just the technology without the operationalization or without the right skilled staff, right, to meet up with it. You know, I try to balance that out and look at that and apply those kind of learnings, both from science and art history and liberal arts and marketing, into the field at large.

Jon McLachlan

Wow, that's spectacular. It sounds like you both complement each other very well, which is really important in a startup. Got to hit the ground running, and everyone is a clone of each other, then you're kind of preaching to the choir all the time, and the company won't be as resilient as it could be if you had a nice, diverse team. And it sounds like you both bring so much different experiences to the table. So nice job. Would you like to share one truth that you see with the world that most people tend to miss?

Grace Chi

It's funny because I had thought of some earlier, but now I'm [like] none of them sound that good. Dan, do you have anything?

Dan Sherry

Yeah, I mean, when I'm looking at our industry, I think that the industry tries to move towards this, building the newest and like latest and greatest technologies, but we haven't really nailed the foundation yet. I feel like there's an opportunity to take a step back and try to smooth over a lot of those [basic processes] that a lot of small [and medium-size] businesses are struggling with. [...] like a lot of these new ideas that we haven't really seen before. And like [investors are] trying to invest, they want to look for new ideas that haven't been tried.

Jon McLachlan

Right. They want to take risks.

Dan Sherry

Yeah, right. But there's a lot to do with innovating or changing existing ideas or improving them. And actually, I remember reading a while ago that, according to research, the most successful companies are actually iterations over previous ideas versus ideas that are completely new. So I think there's a lot of opportunity there.

Jon McLachlan

I see what you mean. Innovation is very often taking ideas that already exist and making them more accessible, sharing them with a wider audience, removing barriers to entry. [I mean,] to innovate doesn't require that much risk taking. You just put together what you've noticed already works, works well, and you can make it available and accepted across the entire world to help change things for the better. No, I get that entirely, Dan.

Dan Sherry

Yes, yeah, [I'll just add,] like when you're iterating over existing ideas, you know, it's not a new sell to new customers, that they're already familiar with that type of solution. So it's actually easier, like, it's easier to enter markets that way too.

Jon McLachlan

Right, because what you're selling is already connected to what they expect to build or to find out there. And you're just doing a lot of that manual work for them, stitching it together in a way that adds value more quickly. Awesome. Was it your experiences in the industry that led you to see this?

Dan Sherry

You go to like meetups and you talk with a lot of people that are in, that are like also engineers or responders, and they're struggling with the same problems that you are. And there are problems that are like, you know, shouldn't this have been solved? Like, we see all these new companies coming out, it's like, shouldn't more people be trying to address the problems for organizations that aren't as mature or who have like a smaller budget? So yeah, I guess that's where it was, just sharing the frustration with other engineers who are trying to automate and support these vendor solutions, or [incident] responders who are really just trying to understand if something is a false positive or [if they should dig deeper]. So just those frustrations that, okay, maybe we need to take a step back, if understanding these problems better, it's a better way to solve them.

Jon McLachlan

Yeah, that makes total sense. And they're lucky to have someone like you lead the charge and notice this and sit down and think through the bigger picture, take a step back and really help everyone build a more secure future. Because really, at the end of the day, everyone that has a cloud environment has responsibility to help protect those systems that are up there in the cloud, or data. Same thing, you have responsibility to protect the data that's up there in the cloud too. And if things are priced out of reach or too complex to be used by the smaller markets, the SMB markets, or even fellow startups, then there's going to be huge gaps in the market. So inviting everyone to have a place at the security table with that free tier that you guys have, very admirable. And it'll take a lot of the market share that way, too.

Grace Chi

Right. The, yeah, that accessibility is important. And I think one thing the industry is changing a little bit, and I know it's like not easy, but another truth that started with [Pulsedive], maybe not in the earliest stages, but shortly after there was a free community tier, is the ability to share intelligence. Because when threat intel hit the market, it was a little bit convoluted. Like everyone wanted lots of feeds, feeds were coming out. They come in the dozens, if not thousands, right, at this point. And no one can really truly benchmark the quality, the efficacy, the relevancy of various lists of IOCs. And what that resulted in is every organization has threat intelligence, even if they don't have threat intelligence. If their intel lives in emails or blog posts like that they're linking to each other, that's what it is. And it's not great. But being able to create venues in which multiple users can share intelligence, add commentary, submit things for other users makes it so that it's not like every SMB that has like very limited resources and also lack of like expertise and understanding, they're not living as individual troops trying to fight this very large, growing, and evolving enemy, multiple enemies, but that you can start bringing it together and working as a united front. I know that there's a ton of trust groups, and there's also coalitions, there's public-private partnerships. So there is a lot of work being done, but at this point, it's still quite disjointed, and it's really hard to keep up. So Pulsedive is looking to be at least one niche of that space that's trying to help each other, ourselves, communities, individuals, [hobbyists], and obviously organizations in bringing this threat intelligence together.

Jon McLachlan

So there's a strong sense of community amongst everyone, and you're all in the same boat together, benefit from each other's knowledge. How do you incentivize folks to give back into the community?

Grace Chi

Offering free things is a really great way to make it like giving value before asking for anything is, is a fantastic, awesome way to give first.

Jon McLachlan

So the community can give first. And then if you give back, it just continues to pass that love forward.

Grace Chi

In a lot of ways, yes. The other challenge that we have, though, is that you want people to contribute, but you also want to protect them. So we have a lot of safeguards in place where you don't actually know who it is, or it's a username, or they can do their intel research without submitting and sharing that information with the actual community if it's sensitive. So we're always like trying to toe the line of like you opt in to share, not you're forced to share. But Dan, as far as your early, I guess your early story on giving a little bit, getting back, and then building Pulsedive to like V2 and V3, what would you say was like a major turning point that a community started to evolve?

Dan Sherry

Yeah, well, in the beginning, it was going to, it was supposed to be like an enterprise platform to compete with a lot of the other ones that were coming out at the time. But when you're trying to get people to look at it, [you need the data in it,] so they can kind of understand what the platform does. So I started working on putting data in the platform and, you know, try to show people. But, you know, people didn't want to go to some login screen to try to discover something that they don't really know that they need or that they want. So I started making a lot of stuff accessible for free without an account, to try and lower the barrier to entry. And then people were more interested in using the platform and the data. And so that's how we saw this opportunity with a lot of people who are finding value in just the [community tier] and just the data. And they're willing to pay for the data. So it seemed like the right way to go. And so we actually discontinued the enterprise [tier] for a while. And for the past probably year or so, we have been [ramping] that up again, because we're at a point where now the value of [Pulsedive] has been proven. So people want this, people want that value within their environment. [As far as] like getting people to contribute, you'd actually be surprised at like the amount of people who just want to help smaller organizations or who want to put their data out there so that people can use it. I mean, there's so many open source projects and repositories, but yeah, I mean, it's great to mention like a lot of it pretty disjointed. [So I think] you do want to provide some value to solve their problem, but I think they just want reassurance that you're also willing to provide this data and make it accessible for other organizations, and that you're good, that you have the flexibility to support those types of data sets, and then you're going to be around for a while. Because if they're submitting a lot of data to this platform, they want to know that like, okay, people can actually use it. I'm not wasting my time submitting to like a startup that's going to [fold], and you're able to accurately represent the data that I have so that people can use it in the way it's meant to be used. So yeah, I think a lot of people are willing to contribute with the right tools.

Grace Chi

And in addition to contributing, so like when we talk about contributing, and I think what Dan's thinking about is like sharing data, submitting IOCs, IPs, URLs, associating with threats, adding comments with blogs, the other way that they contribute, and I will be frank, I was surprised, was like, obviously, feedback for the community tier. People want it because they know that that's going to benefit them. They provide user input, complaints, what they love about it. So when we conduct that user feedback, it's great. When we were doing research into the Pro tier, which had launched a year ago, users are also really excited. And it was like, I asked maybe 30 people that I somehow knew or didn't know, that used or didn't use Pulsedive, and they were all willing to hop on the phone because they know that even if this is a paid product, we're trying to be affordable, we're trying to meet like a specific segment that there's a gap for. And that, you know, even if they were not fans of the community platform, that they wanted, they supported our vision, they supported our effort. And I did not expect people to want to help, you know, like provide input for a paid product. And that helped, and that made our product much better. It made people see the value. And you know, we had like a great Black Friday because of it. So it's, the community is so open and great. And if you contribute to it, they give back in [droves].

Jon McLachlan

It sounds like you're doing a great job of building that community and building a sense of, you know, we're all in this together. If you give, then the community will always be giving back to you as well, and set up a situation where people could feel like they're part of something bigger. That's really what you want in a community, right? I've also heard, I think it was actually from a VC that mentioned this, that if you don't have community, then eventually you just become commoditized and you'll be like any other product. And you know, a Kleenex is a Kleenex, no matter what the brand is. But if you have a strong sense of community, then there's always going to be that that can help drive forward your brand recognition. And not that your brand recognition is going to be synonymous with the community, but that there'll always be a group of people. Because at the end of the day, that's, I think, that's what all of this stuff is about, and that's why we do this. [Those] people that we're trying to help, like in a very concrete and tangible sense. So if there's a gathering space for that group, and you can form a sense of community around other people that are struggling with the same things, then now you have a very long and lasting brand.

Grace Chi

Right. And when we're this early, like us as people, like we're very different, but we are very much part of that brand too. So we participate in the community and things that we enjoy. We lean into our strengths. And as part of the, instead of like collateral damage, it's like the collateral benefit is we talk to thousands of CTI teams. We've helped people get placed in jobs just because we know people both hiring and job seeking. And that's really important. And we help advocate for, you know, diverse and new talent coming in. And that is just part of the culture we have, because we want a great product, but to be a great product, you have to understand the market. And to understand the market, you have to participate in the market. And that's where we are now.

Dan Sherry

No, that's exactly what I was [going] to say, that you need the community, but you also need to be a part of that community to make sure that you're looking [out for it].

Jon McLachlan

Yeah, great. Yeah, exactly. So tell me about the best day that you've had at Pulsedive. What was that day like, and why?

Grace Chi

So I'm on the COO side. So I'm always like looking at measurements and operations. Where are we focusing? And so whenever we have QBRs, so quarterly business reviews, in which I'm just wading through a lot of data and then putting things down, it always feels like such a grind. But then you look and you sit down and you measure the change quarter over quarter or year over year. And when you're living in a small startup where every day is chaos, you're trying to learn something new, there's new problems, you feel like you can never keep up, you feel like you don't make that much progress. But then you sit there and you talk, and it's like a really long meeting we have every quarter, where you're like, wow, look at who our customers are, look at who's been signing up, look at how they've been using us, look at what we succeeded in and also didn't expect. You know, there's not a specific quarter that I would say was the absolute best, but taking that time just to like really sit down and like look back and then also plan forward has kept us, or at least me, Dan, you can tell me if you agree or not, very aligned and interested in seeing the value of what we're doing.

Dan Sherry

Yeah, yeah, I totally agree. I mean, it's really [exciting] to see it grow from like the vision that I had, like working nights and weekends, like, you know, years ago. It's just wild.

Grace Chi

Working nights and weekends now and during the day.

Dan Sherry

Yeah, yeah, I guess [that's true]. I like, I guess I'm still on that schedule, but because I'm not doing like nine to five like I used to, [I can sleep in]. But yeah, I mean, it was definitely like the first [big sale] that we had a couple years ago, when I was still on my own, that was when I was like, wow, like, [I can do this.] Like, this is like a viable business model.

Jon McLachlan

Yeah, yeah. How long, how long did it take to make your first sale?

Dan Sherry

For like the first [serious] sale, it probably took about a year. I mean, it was a while of just building the product. But I mean, building the product wasn't even the [hard] part of it. It was [getting people] [...] and then getting feedback and making sure that we were offering something that like provided enough value where people could justify a line item budget for it. So that, yeah, it took a while. I was just doing sales and [business] development and

Jon McLachlan

Yeah. But you cracked the code and you made, you close the deal. Yeah. And how long ago was that? Like a couple years?

Dan Sherry

Yeah, it was a couple years ago. That was like four, three, four years [ago].

Jon McLachlan

And was that sort of like the thing that tipped you over the line? And did you leave your day job at that point? Or because I know you mentioned this was a passion project in the very beginning, but

Dan Sherry

And that was a year after, after I was on my own.

Jon McLachlan

Oh, so you were already full time, and that year passed, and you have kind of like still in experimentation mode.

Dan Sherry

So if you're going to ask like what the worst [time] was, it was like that first year when I was like out of money, basically. And when I realized, like, okay, I need to probably start working again. So I started contracting. And it was actually like right when I started contracting when someone came out of the blue and were like, hey, we're interested in your highest tier. You know, can you send us an invoice? And so that, it was, yeah, that year was just a roller coaster.

Jon McLachlan

Wow, that's spectacular. They just showed up out of the [blue] and was like, can you send me an invoice? That's unheard of.

Dan Sherry

Yeah, yeah. Yeah, because they're like, oh, we're interested in the feed. And I thought it was like probably a small, like one of the lower tiers. And they're like, no, yeah, we want the [highest] tier, we're ready to purchase.

Jon McLachlan

That's pretty exciting.

Grace Chi

Yeah. Just to, just to add to that, like, that, like, who are these people who reach out to us? That happens all the time. And that's only because we have, one, no like outbound sales process. We don't do paid advertising, right? Like we're not really tracking specific like users either. We just let people use what they want, but then you penetrated the market, and we have some visibility, or at least we understand what our users are thinking. But so often something will come in and they'll be like, can you give us an invoice for this and that package? Blah, blah, blah. I'm like, Dan, have you ever talked to these people? And he's like, no, don't you know who they are? I'm like, no. We're like, cool, all right. [Like, working on that invoice now.]

Jon McLachlan

That's awesome. Do you ever ask how people learn about you then?

Grace Chi

Every time. Like every time.

Jon McLachlan

And so what do they tend to say?

Grace Chi

A lot of people had used Pulsedive before and they liked it. They thought, we hear like, oh, the interface is great, or oh, I could set up the API really easily. And you know, the way the security industry works, people are jumping around all the time, and then they share, you know, news, and then they bring it to their new companies, right? Other ones, like sometimes Pulsedive's listed in like an internal wiki for like, oh, if you're doing threat intel enrichment or research, use this tool. So then new junior analysts come to us. And then other times, like for some of our larger [prospects], it's because in all those secret dark alleyways on Slack and Discord, they put out an ask and it's just all warm referrals. And we've never heard these people, but somebody who we work closely with, who's a big advocate, will be like, oh, check out Pulsedive. And that's where they come from. So it's all really organic and kind of like grassroots, which we like a lot.

Jon McLachlan

So you're bootstrapped. You have viral grassroots. I'm sure everyone that's listening to this podcast that's a VC is wondering, are you going to be raising? Are you going to like throw fuel on the fire and really grow an exponential rate and do that hockey stick thing?

Grace Chi

Oh yeah, the hockey stick that every startup says they can do. One thing I wanted to add actually to, which has enriched Pulsedive a lot, but comes from having this community, and we're so lucky, is that integrations are the name of the game. You have to integrate every tool with every tool. And our users are often the ones who start it off, like who will reach out to a tool being like, I want a Pulsedive integration, or go out of their way and make their own community marketplace integration. And that in and of itself has built and given us like almost like development capability that didn't come from us, but because they know they could use it out of the box, because they have the value, because they have that expertise and they're trying to solve this problem for their own company, they bring it back to us. And then of course, you know, we thank them, we provide, you know, whatever kind of, not compensation, but deals, discounts, and just keep it going like that.

Jon McLachlan

[Do you] have like an open source GitHub with the integrations that are all open source, or

Grace Chi

It's our API documentation.

Jon McLachlan

It's your API documentation. Okay.

Grace Chi

And Dan's happy because he can just answer some quick questions, and then it just magically appears. And then we get new customers because they found, you know, this SOAR integration or that SOAR integration in this other tool. Yeah, it's the best when we get development efforts that are not, that we didn't even know existed until it's like published and people are coming to us using it.

Jon McLachlan

Yeah, that's amazing. And so you don't, you don't have to spend money on marketing. It's all word of mouth, and it sounds like it's growing very rapidly, and you're just expanding and using the help from the community to expand into different tools, different markets. I guess as you integrate those different tools, you're actually opening up new markets for yourselves too.

Grace Chi

Different use cases, too. Like when we talk about good days, when we launched Pro, you know, we do discovery, we do user research, we try to prepare ourselves for the most successful version of this product that we can build. But then they come back and people will be like, I found funkiness. We're like, great, that's perfect. You know, they're like the single security person, and there was a detection, or, you know, something, however they use Pulsedive, help them protect their company. That's the end goal, right? So a lot of times typical use cases, security operations or just like doing research, they find funkiness, they pivot. Awesome, right? That's what we want to hear. And people don't always tell us, but when they do, it's like, we always have, we have a feel-good channel in Slack that's private, where we just send kind of feedback to each other and keep us motivated. But then we get like these like super users who don't come from a traditional use case. Maybe they're like red teaming and they're doing recon, or they're doing like vendor evaluation and they're doing technical due diligence. And they help us when they come to us being like, oh, have you thought about this feature? We're like, why? Why do you, you know, what are you doing? And they tell us, and they're using [Pulsedive] in ways we didn't even dive into. Like, sure, we know there's a lot of applications, we're sitting on a ton of data and we process, but they are the ones that are basically guiding us into new markets to test, to do research, to validate, to add functionality as well.

Jon McLachlan

What's the most surprising ask that you've had?

Grace Chi

Ooh, surprising ask. Dan, do you have that?

Dan Sherry

[Surprising?]

Grace Chi

Not so much mind blown, but like a lot of users that were like, oh, we're surprised that you can look at this tool that's really optimized for like security operations teams. They come in, they do like anti-money laundering, fraud prevention or fraud detection, or once again, like third-party evaluation of tools, where like we see that that makes sense, but [you're not designed for it].

Jon McLachlan

Do you ever get a little suspicious when you figure out or you hear that a red team person is using your tool? Maybe they're using it to try to cover their tracks, to see if what they're about to do is going to be detectable, or

Dan Sherry

I see that like a lot of red team people use us for kind of like that threat intel background, or like when they [do] pen tests and stuff like that.

Jon McLachlan

Like initial scan. Like, hey, let's see what our starting point is, our baseline.

Dan Sherry

Yeah, or if like we'll show information, like if there are IOCs that [have] been seen on [feeds]. So if there's like, you know, maybe a company asset that was seen on one of our feeds or that somebody submitted or something like that. So I think it's those two use cases are pretty much aligned.

Jon McLachlan

Great. Okay. Nice. Okay, so what about the worst day at [Pulsedive]? You had like a just a horrible, a horrible day, and for whatever reason.

Grace Chi

My not one-day answer was like, it was a slow, like, dreading [...], but like when the pandemic hit, all budgets were frozen, right? Like [threat intel] was a great field to be in. We did not see any dip. Actually, we probably saw an increase in user from free users. And everything that was about to be purchased, or, you know, no one knew what was going on, from like basically end of Q1 through end of Q2. So everything was closed, nobody was hiring, nobody was [...], everyone was trying to hunker down and see what happens. So we were like sitting there like counting out, Dan and I were sitting there like counting out our runway and like counting out what expenses we can cut and making sure that we could really last. And we were in a decent position, but once again, bootstrapped. So it's not like sitting on $5 million cash. And so when that finally did lift, and we were actually able to like [four or five X our] revenue for the year, because Q3 and Q4 really recovered, and cybersecurity as an industry is just booming, it was a major relief. So that's really six months of a low humming bad day.

Jon McLachlan

That counts as [many days]. Six months of a bad day. Wow, that's quite the bad day.

Grace Chi

It was still like sales and leads. It was just like everything got dampened.

Jon McLachlan

Right. And we hear that a lot across the industry, especially with startups, for 2020. Yeah, I think the pandemic really hit everybody. What about you, Dan?

Dan Sherry

Maybe the same. Yeah, I mean, [pretty much] the same. I mean, it's also like I said earlier, that first year, that was really tough, thinking about reaching out to people and being like, hey, like, do you have any opening specifically for this, for this type of work? I think for me, that was really hard, because when you come into a startup, like you definitely do it confidently, right? Because you have like this new idea, and like the early feedback [is good], and you know, you have a couple people who are asking you about some of your products. But when you just [keep] doing it for so long, and you haven't gotten those initial sales yet, it's just really tough to be like, okay, I got to [...]. Because like you can still [...] [nights] and weekends, but it's kind of like taking a big step back. But I mean, luckily, now we're in like a great place. So it was hard back then, but [...].

Jon McLachlan

So yeah, just not getting the feedback that you want from the marketplace by not being able to close the [sale] [...]. Yeah, that could be a tough spot to be put in, especially because your heart is in the right place and you're pursuing your passions. But if the market doesn't respond quickly, you know.

Dan Sherry

Yeah, [I saw a tweet] today that like really resonated, and it was something like: failure is the default, and it's really the resilience and fighting that failure like every day eventually would get you to a better place. So yeah, that definitely, yeah, that's where we, we hit that first year. Yeah, but I mean, it's like when you're first starting out, and you know, again, you're [waiting] for that first sale, it's like, just with extra disappointment, because you don't know what to expect, right? You're new to the side of things where you're selling to people. So it's really just like just finding [ways] to keep going. And especially when you're bootstrapped and you're [...] you run out of your savings, but you still have opportunities, and like you don't have to, like when I was in my own, I didn't have to let anyone go, right?

Jon McLachlan

Sounds like you have true grit and you really pulled through. And now all of that's going to be paying off for you here and in the future too. So when we do look into the future, I'll leave it up to you of how far you want to look into the future, but tell me about what the next milestone of success looks like for Pulsedive.

Grace Chi

I'll take a first step and then Dan can add to it. In the short term, like any nice startup, you know, we want to make sure we're not churning customers, that they're either, you know, it was called being retained or upselling, which is something we've also witnessed. We kind of have this nice ladder where there's free and then there's individual pro and then there's data subscriptions and then there's a full platform. And we have some users who are just like bouncing their way up the ladder, which is exactly a validation of how we [position] and how we are in the market with these products. So 100% keeping users satisfied, having them continue that referral, that word of mouth. And then in addition, being able to have a voice and like create, I don't want to say thought leadership because everyone, you know, so [hackneyed], but being able to take and utilize this research, all this data we're sitting on, the communities that we're building, and then more meaningfully, more intentionally contributing to the future of the industry as well. And with that, it comes with like working closely with enterprise-level users, with communities, with programs, profit and nonprofit types. And then in the medium long term, it's building out that community [forum] functionality, where individual users might be able to, and this is all like, you know, kind of on the vision, but we haven't committed, we haven't put a timeline to it yet.

Jon McLachlan

Sure.

Grace Chi

Sharing their intelligence with specific user groups or trust groups, having that Pulsedive be a platform that [...] users can work with each other or across organizations as well. And Dan, I know you have some more thoughts regarding how that would look within the platform technically and people-wise.

Dan Sherry

For what, for what part?

Grace Chi

The like supporting the cybersecurity and the threat intelligence community within the [Pulsedive] product, with their own feeds, with their own data, their own research.

Dan Sherry

Yeah. [...] is like, you know, we've talked before about having people contribute, but we want to be that place where like, you know, people can publish interesting research and stand up their own feed, and yet contribute in like a much more automated way, and really grow that community.

Jon McLachlan

Okay, so your vision of success is when you step into an elevator, and there's two engineers already in the elevator, and they're arguing about how to grab the best and latest data for threat intelligence. And then finally, one turns to the other and says, oh, let's just be done with it and use Pulsedive.

Grace Chi

We'll use that story. Yeah, when [we, oh,] we'll come back to you when that happens to us. You know, it's, it is fun because like when I started, and this was two years ago, when I joined Dan, two years, I think two years into his experience, and it was growing beyond just him, and then he invited me in because I have a very different way of looking at the world and things that I enjoy and strengths. We were sitting at a BSides DC conference, and this was the last one before like COVID hit and all the BSides were canceled, like in [person] [...]. And we're like sitting there, like listening to some research. And I don't know where, like Pulsedive shows up on the screen. And we're like, what? Like, oh, we've never, we don't know this guy. And we're like, that's awesome. And that kept happening. And we're like, it is so motivating, because we're living, you know, a lot of days, we're coding, we're working on the business. We don't get like, we see the user activity, but we don't see the impact necessarily. And then when we put ourselves in the community, even not trying to sell, just attending to learn about things in security, like we see our name, and we're like, wow, that's, wow, that's really spectacular.

Jon McLachlan

So you just haven't gotten into the right elevator yet, then.

Grace Chi

Exactly. And like some forums, like sometimes if I just like [Google] Pulsedive and [...], and they'll, people will be like, oh, Pulsedive is amazing, you should check it for this and that. And I'm always like, awesome, sweet. That's the online elevator.

Jon McLachlan

That's spectacular.

Dan Sherry

Do you remember, like, we were, we went to like they had like an after party at [...] or whatever, like at a local bar, and we were there, and someone, like, I don't remember exactly [...], like, oh, what do you do? [...] like, yeah, [...] building that. And he was like, you built [Pulsedive]? And that was like, that was like wild. Like, that never happened.

Grace Chi

Dan, Dan doesn't realize because he lays so low, there's like a world out there where people really admire and are grateful to him, but then he doesn't like necessarily see them. And then so we get a lot of users who come in and they're like, oh my God, Dan, you built this whole thing, or like, you're still like building it out. And you know, you didn't use, you know, pre-built tools or frameworks. It was like all a lot of native development. And so people like don't necessarily understand. And at the same time, that's when we hear from users. They're like, oh, we thought you were bigger. We thought you had more people. We thought you had more, you know, we thought you had funding. And we're like, good, we want to keep punching above our weight class.

Dan Sherry

A lot of that impression is from Grace too. I mean, like, we don't have a full marketing team. Like, that's all Grace [...] the impression that we're, that we're bigger than we are.

Grace Chi

It's not supposed to be an illusion. It's just, you know, I think

Jon McLachlan

It's a reflection of your reality and your humble beginnings. And now it's all paying off.

Grace Chi

I think what I enjoy the most is that marketing gets a bad rap. And I get it, that people don't necessarily [do] marketing well. I fully understand the frustrations. But as far as the discipline of like finding out what's authentic, finding out why users like you, why they want to talk about you, and then applying that in a way where we're not forcing, you know, we have a very consultative sales approach. We just put ourselves out there, we try to educate, we do what we can with the resources we have to have a presence that reflects the reality. That's been a lot of fun, because I get to like take all the skills I've built and learned, but I didn't necessarily believe in previous companies or for previous products, and then do that for a community that's like cheering us on every day. Like, that's a completely, like, 180 from places I've worked in the past.

Jon McLachlan

It sounds like you've enjoyed a huge level of success already, and going to continue it well into the future. Well, I'm just going to say thank you so much, both Dan and Grace, for joining me. We'll have to have you on again at some point in the not too distant future, and we can see how [Pulsedive] has changed and has changed the world and made it a more secure place for all of us. And yeah, just, I'll leave you with a huge thanks, and we'll connect again.

Grace Chi

Yeah, thank you so much. Maybe in the future, we'll just have a user who likes [Pulsedive], so we don't have to keep talking about ourselves. It's more fun that way.

Dan Sherry

Yeah.

Jon McLachlan

Sure, sure, that works too. Thanks so much, guys.

Grace Chi

Thank you.

FAQ

Questions this episode answers

What is Pulsedive?
A cyber threat intelligence startup that offers both a platform and data. It enriches indicators of compromise with external scanning and scoring, correlates them with threats and threat actors, and gives analysts transparent, raw but structured data. Most of its users are blue team practitioners.
Can you use Pulsedive without an account?
Yes. On this episode, Grace Chi said anyone can use the freemium community tier without registering, run passive or active scans, pull back data and never make an account, and that Pulsedive does that on purpose.
What is the difference between a passive and an active scan?
In Pulsedive's FAQ, a passive scan looks up WHOIS, DNS and metadata without contacting the target. An active scan reaches out to the target with a headless browser and collects HTTP requests, TLS certificate data and cookies, which gives more detail and makes more noise.
Why is it hard to judge threat intelligence feeds?
Feeds come in the dozens, if not thousands, and Grace Chi said no one can benchmark the quality, efficacy and relevancy of the lists of indicators. Dan Sherry described responders trying to work out whether something is a false positive.
How does Pulsedive protect people who share intelligence?
Contributors can stay anonymous or use a username, and can research without submitting their findings to the community when the work is sensitive. Sharing is opt-in.
How do new customers find Pulsedive?
Pulsedive had no outbound sales process and no paid advertising. People used it before and brought it to new jobs, internal wikis list it for enrichment and research, and people who ask for a tool in Slack and Discord groups get warm referrals.
What did the pandemic do to Pulsedive?
Grace Chi called it six months of a low humming bad day. Pulsedive saw no dip in users, but from the end of the first quarter of 2020 to the end of the second, budgets froze and nobody was hiring. The third and fourth quarters recovered.
What happened to Pulsedive after the episode?
Eight days later, Pulsedive published a report on threat intelligence sharing. It released Pulsedive 5 with MITRE ATT&CK data in February 2022, launched Pulsedive Enterprise in August 2022, released Pulsedive 6 that November, and launched a documentation site in March 2026.
