COGENT Security on Wednesday announced raising $42 million in Series A funding to develop autonomous AI agents for vulnerability remediation, with Bain Capital Ventures leading the round and participation from Greylock Partners, Definition, and executives from OpenAI, Abnormal Security, and Datadog, according to SecurityWeek. The San Francisco‑based company says the funding brings its total raised to $53 million and will be used to accelerate product development.
Cogent’s agentic AI platform automates investigation, prioritisation and remediation tasks, connecting and normalising vulnerability data across environments while handling scanner noise and incorporating business context. It prioritises risks based on environmental factors beyond standard severity scores, surfaces emerging threats, and generates tailored remediation plans that are integrated into existing workflows.
“Security teams are drowning in coordination work: chasing down system owners, writing tickets, proving fixes happened. We built AI agents that handle that work end-to-end, so security teams can finally keep pace with attackers,” said Vineet Edupuganti, CEO and co‑founder of Cogent. The announcement was reported by SecurityWeek on 18 February 2026.
