RunSybil Raises $40M To Automate Offensive Security

Offensive security startup RunSybil Inc. said it closed a $40 million funding round led by Khosla Ventures to scale its AI-driven offensive security platform. The company uses autonomous AI agents to perform black-box red-team testing, chaining minor flaws to find critical vulnerabilities and reporting a 90% reduction in false positives versus standard scanners. RunSybil will use proceeds to expand R&D, agent capabilities, and go-to-market teams.
Key Points
- 1Raises $40M led by Khosla to scale AI-driven autonomous offensive security testing platform
- 2Uses autonomous agents to simulate human attackers, enabling black-box red-team testing without source code
- 3Reduces false positives by 90% and finds chained vulnerabilities missed by pen tests and bug bounties
Scoring Rationale
VC-backed funding validates approach and boosts reach; vendor claims lack independent verification, limiting immediate operational confidence.
