Cogent Security Launches From Stealth With $11M From Greylock Partners to Transform Vulnerability Management With Agentic AI

Cogent Unveils AI Taskforce for Vulnerability Management, Helping Businesses Neutralize Threats Before Attackers Can Act

SAN FRANCISCO--(BUSINESS WIRE)--Cogent Security, the company pioneering the world’s first AI taskforce for vulnerability management, today announced its launch from stealth. The company was initiated in Greylock Partner's Edge program and raised $11 million from the firm, which incubated Palo Alto Networks and Abnormal AI, and backed Okta and Wiz. Cogent Security’s latest funding round also included participation from Lockstep and a group of strategic angel investors from leading organizations such as OpenAI.

Vulnerability exploitation is now the fastest-growing cause of data breaches. The arrival of generative AI has triggered an explosion in code and software development, which has driven a sharp increase in security vulnerabilities and left many organizations exposed to attack. Meanwhile, threat actors are using the same AI technology to exploit vulnerabilities faster than ever.

Cogent Security was founded by Vineet Edupuganti (CEO), Geng Sng (CTO), and Thanos Baskous (VP, Engineering), who, over the last decade, spent countless hours remediating vulnerabilities at security-conscious companies like Abnormal AI, Coinbase, and Blackstone. Through this work, they saw firsthand just how ineffective the process of vulnerability management had become.

“With AI, threat actors are moving faster than ever, which is putting a huge strain on legacy vulnerability management frameworks,” said Vineet Edupuganti, co-founder and CEO of Cogent Security. “These frameworks rely heavily on manual workflows like context gathering, risk assessment, and coordination between security, infrastructure, and IT teams. However, these human-driven processes are simply too slow and inefficient to keep up with modern threats. That’s why we built Cogent: to bring automated, real-time intelligence to the vulnerability management lifecycle and help businesses neutralize cyber threats before attackers can act.”

Cogent has developed the first AI taskforce for vulnerability management, providing specialized, purpose-built AI agents that act as force multipliers for in-house security teams. These agents use expert-level reasoning to autonomously execute time-intensive tasks across the vulnerability management lifecycle, including: gathering context on the inherent risk of infrastructure and applications; prioritizing top risks; identifying the right fix; shepherding issues to resolution; and packaging reporting for executive stakeholders.

The platform’s AI-native architecture can ingest petabytes of historical data that capture the inner workings of an organization. This means that from day one, customers can deploy agents that already understand their unique organizational structure, workflows, and context. The platform also delivers expert-level decision making through its domain-specific AI agents, built to match the same judgment as experienced security, engineering, and IT professionals.

Cogent is transforming vulnerability management for some of the world’s largest and most complex organizations including Fortune 500 enterprises, public companies, and high-profile universities. Across these real-world, large-scale deployments, Cogent has reduced the manual work required of security analysts, increased the rate of resolution of critical vulnerabilities, and substantially reduced the time to fix vulnerabilities.

Lucas Moody, CISO at Alteryx, shared: “Vulnerability management has remained an unsolved challenge for decades. Cogent changes that. It’s not just another tool — it’s a true system of intelligence, powered by agentic AI, that delivers real risk reduction and efficiency. It understands our environment, makes informed decisions, and takes action. It’s like having your top security and engineering talent on every issue, around the clock.”

Cogent has assembled an elite team of applied AI and distributed systems engineers in Silicon Valley, who have built platforms, infrastructure, and domain-specific AI agents at mega-scale companies such as Coinbase, Tesla, and Google Research. Cogent will use the funding to expand this team and make additional investments in its proprietary language models and infrastructure.

Saam Motamedi and Corinne Riley, Partners at Greylock Partners, said: “Vulnerability management is right now arguably the most important problem in cybersecurity, which in turn is one of the most valuable markets to adopt AI. The Cogent team is one of the strongest we have seen in cybersecurity, bringing a rare blend of security and AI expertise. The company is AI-native to the core, with incredibly strong product velocity and customer centricity, which has enabled early success with large enterprise customers.”
