Company Overview
XBOW is a cybersecurity company building an autonomous offensive security platform that uses AI to continuously identify, exploit, and validate vulnerabilities in software applications. Founded in January 2024 by Oege de Moor, the creator of GitHub Copilot and GitHub Advanced Security, XBOW combines AI reasoning with offensive security workflows modeled on real-world attack techniques. Its platform is designed to perform penetration testing at machine speed rather than relying solely on periodic, human-led assessments. XBOW says its system can discover deep exploits, validate findings, and provide documented attack paths for security teams. The company serves enterprise customers globally and has expanded its platform and customer base as demand grows for continuous security testing in an environment where AI is increasing the scale and speed of cyberattacks.
QueryFeedz Insight
XBOW is positioning autonomous offensive security as an alternative to the traditional point-in-time penetration-testing model. Rather than using AI only to analyze security alerts, its platform is designed to behave more like an attacker by planning and executing attack paths and validating whether vulnerabilities are actually exploitable. The company's rapid funding progression—from $117 million after its 2025 Series B to more than $272 million after its 2026 Series C extension—has coincided with growing enterprise adoption.
