0.security builds an autonomous offensive security team that finds and fixes vulnerabilities as fast as AI writes code and before attackers exploit them.
We've found and fixed dozens of previously unknown vulnerabilities (0-days) in government software across multiple countries and in software running on 3+ billion devices. Today we work with EY (Ernst & Young), leading tech companies and defense organizations.
Our AI agents hack into any software, verify every vulnerability they find, and ship the fix. They run 24/7 across the full stack, from web apps and dependencies down to operating systems and the Linux kernel.
We offer two products: 0cloud, where developer teams connect their repos and get security handled 24/7 at the speed of their coding agents, and our open-source harness, which we deploy & run for tech companies, enterprises and critical infrastructure providers.

Maturity is an evidence-based assessment, not a success rating. It may understate the current stage where evidence is limited. Coverage records documented areas, not a complete or independently audited company history.
