What happened
On June 29, 2026, Straiker announced a $64M Series A (total $85M), led by Marathon Management Partners with Citi Ventures, Illuminate Financial, and Workday Ventures. The platform delivers three integrated capabilities: agent discovery/MCP visibility; pre-deployment adversarial red-teaming via STAR Labs (industry's most comprehensive agentic exploit dataset); and runtime protection blocking prompt injection, data leakage, and tool manipulation. STAR Labs data: 36% of coding agent attacks led to RCE; 91% of productivity agent attacks led to silent data exfiltration. Supports Codex, Cursor, Claude Code, Microsoft Copilot, ChatGPT Enterprise. Trusted by Fortune 500 and frontier AI labs; 15x revenue growth in under a year.
Why it matters
Led by ex-Palo Alto Networks Prisma Cloud SVP, Straiker is the most credentialed pure-play agentic security company at scale. STAR Labs exploit data is operationally unique — it feeds both pre-deployment testing and runtime defenses in a shared intelligence loop. The 91% silent exfiltration rate for productivity agents is a critical risk signal for any enterprise running Copilot or ChatGPT Enterprise.
Applicability
Enterprises deploying coding agents (Codex, Cursor, Claude Code) or productivity agents (Copilot, ChatGPT Enterprise) at scale; evaluate Straiker's discovery and runtime tiers immediately.
