Security AI platform Cogent bags $42m Series A

February 19, 2026

Cogent Security, a cybersecurity company building autonomous AI agents for enterprise vulnerability remediation, has raised new capital totalling $42m.

The company has secured $42m in a Series A round led by Bain Capital Ventures, with participation from existing investor Greylock Partners and Definition. Founders and executives from OpenAI, Abnormal Security, and Datadog also invested personally. The latest funding brings Cogent’s total capital raised to $53m, just six months after its official launch.

Cogent focuses on what happens after vulnerabilities are discovered. While modern scanning tools can identify weaknesses in software systems, many enterprises struggle with the manual coordination required to remediate them. In 2025 alone, more than 48,000 new software vulnerabilities, known as CVEs, were published – a 162% increase compared with five years ago.

At the same time, attackers are increasingly using AI to identify and exploit weaknesses within minutes of disclosure. By contrast, defensive teams can take days or even weeks to fix issues, often slowed by fragmented ownership records, ticketing backlogs and competing engineering priorities.

The company’s AI agents are designed to automate this remediation process end-to-end. According to Cogent, its agents investigate vulnerabilities, determine system ownership, assess real-world risk within a given environment and generate actionable remediation steps for engineers. They then track fixes through to verified completion. Customers using the platform have reduced exposure windows for critical risks by an average of 97%.

Cogent said it plans to use the new funding to accelerate product development, expand enterprise deployments and further build out what it describes as agentic security systems that operate with governance and oversight at scale.

The platform is built with enterprise controls in mind. Every agent action is traceable and reproducible, and the system integrates into existing security and engineering workflows. It operates under configurable approval gates and policy enforcement, allowing organisations to deploy autonomous AI agents without sacrificing auditability or human supervision.

Early traction appears strong. Since launching in July 2025, Cogent has begun working with dozens of Fortune 1000 companies. Among its customers is CSC Generation, an AI-driven consolidator in commerce that has acquired Backcountry.com and four other brands in the past year. CSC Generation CEO Justin Yoshimura said, “Given the pace of our M&A activity, Cogent is central to our cybersecurity strategy—autonomously managing risk without slowing us down so we can stay focused on deploying AI. Cogent has become a meaningful competitive advantage for us.”

Cogent was founded by operators with experience across vulnerability research and large-scale remediation. Co-founders Vineet Edupuganti, CEO, and Geng Sng, CTO, previously worked at Abnormal Security, while co-founder Thanos Baskous led infrastructure at Coinbase, overseeing large-scale vulnerability remediation. The team also includes AI researchers from Google DeepMind who contributed to the transformer architectures behind ChatGPT, Claude and Gemini.

Vineet Edupuganti said, “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.”
