RunSybil is an AI-native offensive security platform founded in 2023. The company automates application security testing by deploying autonomous AI agents designed to find exploitable vulnerabilities in software and infrastructure. It has raised $40 million in funding.
The company's core product, Sybil, is an autonomous AI agent that continuously tests applications and infrastructure for exploitable vulnerabilities. It operates without requiring source code access, functioning as a black-box testing tool. The agent reasons similarly to an elite human security researcher, dynamically exploring systems, chaining vulnerabilities, and probing authentication boundaries to identify real attack paths.
RunSybil's team includes former OpenAI and Meta security leaders, alongside world-renowned hackers and security professionals from organisations such as Mandiant, NCC Group, Trail of Bits, and Palantir. The company's technical domains span AI agents, offensive security, application security testing, vulnerability research, and black-box testing.
