Cognition Acquires Corridor, the Startup Building Security Controls Into AI Coding Agents, to Expand Devin Security
Today, Cognition is acquiring @corridor. Securing the world’s software is the most important problem in technology today. Let’s get to work!
Context
As agents write more of the world's code, checking that code for security flaws is becoming its own product category, and a leading coding agent company is buying a specialist instead of building alone.
Cognition makes Devin, an AI agent that writes and ships software, and sells a security product called Devin Security. Corridor was founded about two years ago by Jack Cable and Ashwin Ramaswami, who previously worked on cybersecurity in government. Its product places security checks inside AI coding tools so vulnerabilities are caught while code is being generated rather than after it ships. Deal trackers report Corridor raised a 25 million dollar Series A at a 200 million dollar valuation in March 2026.
Deep dive
Cognition, the company behind the Devin coding agent, said on Thursday that it is acquiring Corridor, a San Francisco startup focused on the security of code written by AI agents. Cognition framed the deal in broad terms, saying securing the world's software is the most important problem in technology today.
Corridor's cofounders, Jack Cable and Ashwin Ramaswami, wrote on Cognition's blog that their team will join Cognition to take Devin Security to the next level. They named Cognition's president Russell Kaplan, an early Corridor advisor, and its chief security officer Alex Stamos as people they will work with.
Corridor's product sits inside the workflow of coding agents. Instead of scanning a finished codebase, it applies security controls in real time as code is generated, and the company has said it works with tools such as Cursor and Factory. Deal trackers report that Corridor raised a 5.4 million dollar seed round in 2025 and a 25 million dollar Series A at a 200 million dollar valuation in March 2026.
Neither company disclosed the price or other terms. Cognition has not said when Corridor's controls will reach Devin, or how existing Corridor customers who use other coding agents will be affected. The founders argued that AI agents can now run complete attack chains, so defenders need tools that move at the same speed.
What to expect next
Watch for Corridor's controls to show up inside Devin and for Cognition to say whether Corridor will keep supporting rival coding agents such as Cursor and Factory. The deal also adds pressure on other coding agent makers to offer built in security review, either by building it or by buying one of the remaining independent startups in the space. Pricing changes for Devin Security would be the clearest signal of how central security becomes to Cognition's pitch.
