What it does

RunSybil, a US company with hubs in San Francisco and New York City, sells Sybil, an AI-powered offensive security platform. Its pages say Sybil runs autonomous penetration-testing engagements (black box or white box, where the agents are given source access) and tests live systems with AI agents that learn about the target. It explores authentication boundaries, finds forgotten endpoints and chains weaknesses such as broken authorisation, cross-tenant access and privilege escalation into exploitable paths. Every finding is independently reproduced before delivery and ships with a CWE ID and remediation guidance precise enough to hand to an autonomous coding assistant, with retesting available. Sybil keeps a model of the application and infrastructure and re-evaluates what changed on every deployment, and RunSybil positions it for continuous testing, adversarial exposure validation and SOC 2 penetration-testing reports.
