Cogent Security, an AI-driven cybersecurity platform, announced it has raised $42 million in Series A funding to accelerate development of autonomous AI agents designed to help enterprises remediate vulnerabilities at machine speed. The round was led by Bain Capital Ventures, with participation from existing investors Greylock Partners and Definition. Founders and executives from OpenAI, Abnormal Security, and Datadog also invested personally.
The new financing brings Cogent’s total funding to $53 million, just six months after the company’s official launch.
The company points to a widening gap between attackers and defenders. In 2025 alone, more than 48,000 new software vulnerabilities (CVEs) were published, a 162% increase from five years ago. While modern scanning tools can quickly identify vulnerabilities, remediation remains a slow, manual process. Security teams often must track down system owners, assess real-world risk, coordinate across departments, and verify that fixes have been completed.
Meanwhile, attackers increasingly leverage AI to probe for weaknesses within minutes of new vulnerabilities being disclosed. On the defensive side, patching can take days or weeks. As a result, exposure windows continue to grow across industries, including banking, healthcare, retail, manufacturing, and energy.
Cogent’s platform is designed to close that execution gap. Rather than stopping at detection, its AI agents investigate vulnerabilities, determine system ownership, assess environmental risk, generate remediation steps, and track fixes through to verified completion. According to the company, customers using Cogent have reduced exposure windows for critical risks by an average of 97 percent.
The platform is built with enterprise governance in mind. Every agent action is traceable and reproducible, and the system integrates directly into existing security and engineering workflows. Organizations can configure approval gates and policy enforcement to maintain auditability and human oversight while deploying autonomous agents.
One early customer, CSC Generation, which has acquired Backcountry.com and four other brands in the past year, said Cogent plays a central role in its cybersecurity strategy amid rapid M&A activity.
Cogent was founded by Vineet Edupuganti, CEO; Geng Sng, CTO; and Thanos Baskous. Edupuganti and Sng previously worked at Abnormal Security, where Edupuganti led product strategy and Sng built a machine learning fraud detection system now protecting half of the Fortune 500. Baskous previously led infrastructure at Coinbase, overseeing large-scale remediation of vulnerabilities.
The broader team includes AI researchers from Google DeepMind who helped develop transformer architectures behind systems such as ChatGPT, Claude, and Gemini.
Since launching in July 2025, Cogent says it is already working with dozens of Fortune 1000 companies. With the new funding, the company plans to accelerate product development, expand enterprise deployments, and continue building agentic security systems designed for governed, trustworthy execution at scale.
KEY QUOTES:
“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.”
Vineet Edupuganti, CEO and Co-Founder, Cogent Security
“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.”
Justin Yoshimura, CEO, CSC Generation
“The enterprise security landscape has reached a clear inflection point. The volume of vulnerabilities has outpaced what traditional, human-driven coordination can handle. 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.”
Enrique Salem, Partner, Bain Capital Ventures
“Cogent represents a new generation of security companies built natively for AI agents as first-class operators. Vineet, Geng, and Thanos understand that securing AI agents requires a fundamentally new operating model, which allows them to move faster and deliver measurable customer value early. The technical depth of the team combined with that execution speed makes the customer signal impossible to ignore.”
