Corridor $25M Series A at $200M Valuation: ACSM Platform Embeds Real-Time Security Guardrails Inside AI Coding Agents

The SaaS News·medium signal

Corridor, founded by Jack Cable and Alex Stamos, raised a $25M Series A at a $200M valuation announced March 20, 2026, pioneering Agentic Coding Security Management (ACSM) — a new security discipline for AI-assisted development. The platform runs natively inside Cursor and Factory coding agents, embedding real-time vulnerability checks directly in the AI generation workflow rather than scanning after the fact. The raise capitalizes on documented evidence that AI-generated code has 2.74x more vulnerabilities than human-written code, positioning ACSM as mandatory infrastructure for any team running AI coding pipelines at scale.
