Cogent Security has announced a $42 million funding round to accelerate the development and deployment of its AI agents designed for enterprise vulnerability remediation. Founded in 2025, the startup aims to bridge the gap between identifying security vulnerabilities and fixing them within large organizations.
The company's autonomous AI agents operate across security and engineering systems, automating post-detection workflows while maintaining governance and auditability. These agents handle the complex coordination tasks, such as tracking down system owners and verifying fixes, freeing up security teams to focus on strategic threats.
Cogent's platform integrates with existing tools to ingest vulnerability data, analyze contextual information, and assess real-world risk. It then generates remediation guidance and monitors progress through engineering workflows, ensuring actions are logged and subject to approval gates.
Despite a recent formal launch, Cogent is already working with dozens of Fortune 1000 companies. The Series A round was led by Bain Capital LP, with participation from Greylock Partners, Definition Capital, and executives from major tech firms.
Enrique Salem, partner at Bain Capital Ventures, highlighted the critical need for AI solutions in enterprise security, noting that the volume of vulnerabilities has overwhelmed traditional human-driven coordination. Cogent's AI aims to significantly boost team efficiency.
