Cogent Security has raised a $42 million Series A just six months after launch. Their bet? That AI agents can finally fix one of cybersecurity’s most persistent bottlenecks: the grind between detecting software vulnerabilities and actually remediating them. The round, led by Bain Capital Ventures with Greylock and Definition participating, brings total funding to $53 million.
For Bain partner and former Symantec CEO Enrique Salem who led the round, this is the culmination of a several-year courtship of founder and CEO Vineet Edupuganti. “We’ve known him from pre‑founding the company,” Salem told Fortune. “This wasn’t necessarily his first starting idea, but they’ve proven an ability to deliver against what we’re working on.”
The problem is familiar—and stubborn. In 2025, more than 48,000 new common vulnerabilities and exposures in software were reported, a 162% jump from five years prior, even as attackers increasingly use AI to probe fresh bugs within minutes of disclosure. “There are more vulnerabilities than you’ll ever be able to remediate or imagine,” Salem says. “The Holy Grail is, how do you figure out what to remediate because you’ll never remediate everything.”
Greylock partner Saam Motamedi, who led Cogent’s $11 million seed, says the company has since built “one of the strongest AI teams in cybersecurity.” Both Edupuganti and fellow co-founder Geng Sng came from Abnormal Security, where Edupuganti led product strategy and Sng built the ML fraud detection system that protects half the Fortune 500. Cogent’s third co-founder, Thanos Baskous led infrastructure at Coinbase, where he was in charge of large-scale vulnerability remediation. The current Cogent team also includes hires from Google’s Gemini/DeepMind, Tesla, and Stripe, and already runs its platform in production “across large Fortune 500 enterprise environments.” That traction, Motamedi argues, is “incredibly rare” for a company at this stage.
