Cogent Security, a cyber startup based in Silicon Valley, has launched from stealth with a mission to modernise vulnerability management through AI.
The company, founded by former engineers from Coinbase, Abnormal AI and Blackstone, is focused on bringing automation and intelligence to a traditionally manual area of enterprise security.
The company has secured $11m in funding from Greylock Partners, a prominent venture capital firm known for backing cybersecurity heavyweights such as Palo Alto Networks, Wiz and Okta. Additional investment came from Lockstep and strategic angel investors from organisations including OpenAI.
Cogent Security specialises in building an AI-native platform that introduces agentic AI—autonomous, expert-level AI agents designed to help security teams reduce risk and accelerate remediation. The company claims to offer the first AI taskforce dedicated to vulnerability management, enabling real-time decision-making across an organisation’s IT and security infrastructure.
The new funding will support the expansion of Cogent’s engineering team, as well as further development of its proprietary language models and platform infrastructure. With the increasing pace of cyberattacks and AI-powered exploits, the company aims to provide a faster, more intelligent response to security threats by eliminating the bottlenecks caused by manual workflows.
The platform allows organisations to deploy agents that understand their existing IT structures and workflows from day one. These agents autonomously handle key tasks such as context gathering, risk prioritisation, fix identification and reporting. Early adopters include Fortune 500 companies, public sector institutions and universities, where Cogent has reportedly improved response speed and reduced manual effort.
Cogent Security CEO Vineet Edupuganti said, “With AI, threat actors are moving faster than ever, which is putting a huge strain on legacy vulnerability management frameworks. 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 neutralise cyber threats before attackers can act.”
Alteryx CISO Lucas Moody added, “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.”
Greylock Partners’ Saam Motamedi and Corinne Riley commented, “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.”
