How AI Pen Testing Actually Works (and Where It Breaks)About XBOW
XBOW is a US cybersecurity company that sells an autonomous penetration-testing platform. Its AI agents attack an organisation's applications and APIs, chain weaknesses into working exploits, report only findings they can validate and re-test after fixes. Oege de Moor founded XBOW in January 2024; the company says it was built by the creators of GitHub Copilot and GitHub Advanced Security. It raised a US$120 million Series C at a valuation above US$1 billion in March 2026, and a further US$35 million in May.
