Agentic artificial intelligence for vulnerability management startup Cogent Security Inc. revealed today that it has raised $42 million in new funding to accelerate product development, expand enterprise deployments and continue building governed AI agent systems for vulnerability remediation at large scale.

Founded in 2025, Cogent develops autonomous AI agents designed to address the operational gap between vulnerability discovery and remediation in enterprise environments. The AI agents operate across security and engineering systems to automate post-detection workflows while maintaining governance controls and auditability.

“Security teams are drowning in coordination work: chasing down system owners, writing tickets, proving fixes happened,” said co-founder and Chief Executive Vineet Edupuganti. “We built AI agents that handle that work end-to-end, so security teams can finally keep pace with attackers.”

Cogent’s platform integrates with existing vulnerability management, ticketing and communication tools to ingest findings such as newly disclosed Common Vulnerabilities and Exposures and internally detected weaknesses. The agents then analyze contextual data gathered from enterprise systems to determine asset ownership, map vulnerabilities to affected services, and assess real-world risk based on environmental factors.

The system generates structured remediation guidance and tracks the status of fixes through integrations with engineering workflows. Agent actions are logged, traceable and subject to configurable approval gates and policy enforcement mechanisms.

The Cogent platform’s capabilities include automated investigation of vulnerabilities, correlation of assets to responsible teams, prioritization based on contextual risk signals and creation of remediation tasks for engineers. The agents monitor remediation progress and verify completion once patches or configuration changes are applied.

The system is also designed for enterprise governance requirements, including audit trails, reproducibility of agent decisions and integration into established change-management processes.

While relatively young, having only formally launched in July of 2025, Cogent is already seeing strong growth and is working with dozens of Fortune 1000 companies. Notable Cogent customers include Upwind Security Inc., Alteryx Inc. and CSC Generation Holdings Inc.

The Series A funding round was led by Bain Capital LP, with Greylock Partners, Definition Capital and founders and executives from OpenAI Group PBC, Abnormal Security Corp. and Datadog Inc. also participating.

“The enterprise security landscape has reached a clear inflection point. The volume of vulnerabilities has outpaced what traditional, human-driven coordination can handle,” said Enrique Salem, a partner at Bain Capital Ventures. “Cogent’s AI enables teams to accomplish five times more with the same resources. This represents a fundamental reset of what’s possible in security operations, and we’re proud to partner with this team as they continue to push the boundaries.”

The new funding takes the total raised by Cogent to $53 million.
