  • We're excited to welcome Kimberli Nichols to Cogent as our new Enterprise Account Executive! With extensive experiences at Cyera, BigID, and Varonis, Kimberli has spent her career in data security and DLP, partnering with some of the world's largest enterprises on programs that actually protect what matters. She knows this space deeply and has the relationships to prove it. We're excited for her to bring that same customer-first approach to our enterprise sales motion. Outside of work, she's a proud boy mom to Max (10), Jackson (8), and Hunter (almost 4), three boys who by her own account keep her sharp, competitive, and ready for just about anything. Give Kimberli a warm welcome in the comments! 🎉 #WelcomeWednesdays

  • Vulnerability counts make for good headlines but are not good security claims. Our Head of Research, Duc Hiep Chu, makes the case for why more findings isn't more security, and why false negatives are the real risk to watch. Read more below.

    More findings is not more security. That's the trap I see teams fall into with AI-enabled SAST. These tools are genuinely good now at scanning code at scale and surfacing novel candidate findings. However, sheer volume or novelty in findings doesn't necessarily translate to improved security. A tool can surface ten vulnerabilities and still miss the one path an attacker actually uses. False positives are annoying but at least visible, someone reviews them and moves on. False negatives are the dangerous ones, they just sit there until an attacker finds them first. So the question I keep coming back to isn't "how many vulnerabilities did it find." It's what the system searched, how findings were validated, what got filtered out, and where uncertainty remains. That's the evidence that actually tells you whether the risk of your codebase is reduced. Wrote up the full take on the Cogent blog, link in comments.

  • AI is closing the gap between vulnerability discovery and active exploitation faster than most security teams can respond. Vineet Edupuganti is joining ELITECISOs this Thursday (7/2) at 11:00 AM IST to talk about what defenders need to do differently. Register below.

Register Now : https://lnkd.in/gcYQ6BF8 Join us for an exclusive #EliteKnowledge Session with Vineet Edupuganti, Cofounder, Cogent, as we explore how frontier AI models are reshaping the speed of vulnerability discovery, analysis, and exploitation. Session Title: 𝐀𝐈 𝐂𝐡𝐚𝐧𝐠𝐞𝐝 𝐭𝐡𝐞 𝐄𝐱𝐩𝐥𝐨𝐢𝐭 𝐖𝐢𝐧𝐝𝐨𝐰. 𝐂𝐈𝐒𝐎𝐬 𝐍𝐞𝐞𝐝 𝐭𝐨 𝐂𝐡𝐚𝐧𝐠𝐞 𝐭𝐡𝐞 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐧𝐠 𝐌𝐨𝐝𝐞𝐥. 📅 Date: 2nd July 🕚 Time: 11:00 AM IST 🎙️ Speaker: Vineet Edupuganti, Cofounder, Cogent Security Frontier models like #Mythos, #Codex, and #BigSleep are accelerating how quickly vulnerabilities can be found, analyzed, and converted into working exploits. The traditional model of scanner updates, manual triage, ticket routing, and weeks-long remediation cycles was already under pressure — AI has made the gap impossible to ignore. This session will focus on what #CISOs need to change now: 🔹 Detecting exposure before scanners catch up 🔹 Prioritizing based on real environment context 🔹 Moving remediation through policy-controlled automation 🔹 Verifying that fixes actually hold 🔹 Understanding how AI-enabled defense can help security teams level the playing field During session we'll also discuss how Zero Day Response and Autonomous Remediation can help organizations respond faster, reduce exposure, and modernize vulnerability management for the AI-driven threat era. Join us live for a timely and practical conversation on the future of security operations, vulnerability management, and AI-enabled cyber defense.

  • What a week! Cogent co-hosted back to back mahjong nights in SF. Wednesday we kicked things off with Bain Capital Ventures (BCV) and it was great to see familiar faces from our first event alongside so many new ones. Thursday we teamed up with Reducto for a dim sum and mahjong night at the iconic Mr. Mahjong's, and the energy was unreal. First mahjongs were happening all night at both events, and the energy spoke for itself. We are so excited to be building this kind of community in SF and can't wait to keep hosting. See you at the tables soon!

  • Vulnerability management's growing problem is getting harder to ignore: remediation. The 2026 Verizon DBIR shows exploitation is now the most common way attackers break in (31%, up from 20% the year before). But only about 1 in 4 known exploited vulnerabilities were fully fixed, and the median one took 43 days to close. Teams are finding the threats. They just can't close them fast enough. That gap is what Cogent is built to close. Our read on the DBIR is linked in the comments.

  • Introducing Welcome Wednesdays, our ongoing series spotlighting new faces joining the Cogent team. First up is Steven Do, also known as Stedo, who recently joined us as our Founding Recruiter & Head of Technical Recruiting! 🎉 Stedo has spent his career building elite engineering and leadership teams across Amazon, Dropbox, Brex, and Vanta, giving him a rare eye for talent at every level of the org. We're thrilled to have him bringing that same expertise to Cogent. Outside of work, Stedo is a proud New Yorker who spends his free time Citi-biking through the city's neighborhoods, one borough at a time. 🚲 Welcome to the team, Stedo! #WelcomeWednesdays

  • Excited to welcome some first time Mahjong players tomorrow night!

    Our Mahjong Club was so successful, we're bringing it back for round 2 this Wednesday. We have a very small number of open seats, so request an invitation at the link in comments. Cybersecurity is a game of incomplete information. You never see the full board. The attack surface is bigger than you think, exposures hide in places everyone forgot to look, and even the vulnerabilities you knew about can hurt. Mahjong works the same way. Every discard is a signal, every hesitation a tell, and every action is a calculated exploit against what opponents might be hiding behind blank tiles. Mahjong is threat modeling. Mahjong is an attacker patiently watching your discards, the metadata, the timing, the things you didn't think mattered, assembling a picture you can't see yourself. Here, you yell "Pung!" when you grab what you need. In the real world, attackers take the whole hand, and all you see is your data for sale on the Shiny Hunters forum page the next day. cc Annie Na Grace Hua Cogent

    Introducing Cogenteer of the Month, our ongoing series spotlighting the incredible people behind Cogent. First up is Nina Boord, our Founding Forward Deployed Engineer. 🎉 Nina holds a B.S. in Computer Science from Stanford University and brings a unique combination of technical depth and startup experience to the team. She previously worked on autonomous vehicle safety and validation at Nuro, and has spent time building and scaling multiple early-stage startups along the way. Outside of work, Nina keeps busy in and out of the water, swimming and surfing 🏊, and when she's not there you'll find her behind the decks DJing 🎧. She's also recently taken up the piano, adding yet another instrument to her repertoire. We're so grateful to have Nina as one of Cogent's earliest builders. ⚡ Lightning Round with Nina: Q1: Favorite place you’ve traveled to? I can't choose a favorite, but one of the coolest and most unique would be Senegal! Q2: What was the #1 reason you joined Cogent? So hard to choose just one, but the culture. We grind hard because we care, not because someone is breathing down our neck. People also lean senior and are happy to help us more junior folks learn. Q3: What is your go-to meal? Poke bowl with salmon, octopus, and spicy tuna! Show her some love in the comments! 👇 #CogenteerOfTheMonth

  • Last week, the Cogent team headed to San Diego for our offsite and it couldn't have come at a better time. Since our last offsite in December, we've grown significantly in headcount and momentum. This was our first real chance to bring our NYC team and remote colleagues together in one place, not just to collaborate, but to get to know each other as people. The week was packed with moments that went well beyond work. Team dinners, karaoke, a private charter on the water, unlimited arcade games, and conversations that actually mattered. We were also lucky to have incredible guest speakers Lucas Moody, Jeff Williams, and Jesse Zhang join us throughout the week. Our team came back closer, more connected, and ready for what's next. Here's to many more offsites ahead!
