100-word summary
Cogent Security just landed $42 million in Series A funding led by Bain Capital Ventures, with Greylock and Definition joining in. Their pitch? AI agents that autonomously handle vulnerability management from start to finish, investigating threats, assigning tasks, assessing risk, and tracking fixes until completion. Think of it as a security team that never sleeps. Early customers are seeing a 97% reduction in how long critical risks stay exposed, and dozens of Fortune 1000 companies are already on board. The funding pushes Cogent beyond vulnerability management into broader security operations, potentially automating one of cybersecurity's messiest bottlenecks at enterprise scale.
