March 18, 2026
XBOW, a Seattle-based autonomous offensive security firm specializing in AI-driven vulnerability discovery and continuous penetration testing, has secured $120 million in a Series C funding round, valuing the company at over $1 billion. This capital infusion aims to accelerate product innovation, expand market reach, and support international growth. XBOW's technology, which operates at machine speed to identify and validate security vulnerabilities autonomously, is already deployed at leading security-conscious organizations and has achieved top rankings on the HackerOne leaderboard.
- Why this matters: Government agencies and contractors focused on cybersecurity can anticipate increased availability of advanced autonomous penetration testing solutions that enhance continuous security validation.
- The funding signals growing investor confidence in AI-powered offensive security tools, indicating a shift toward automated, scalable vulnerability management in government IT environments.
- Procurement professionals should evaluate XBOW's offerings for integration into cybersecurity risk management strategies, especially for agencies prioritizing proactive threat detection and mitigation.
- Industry stakeholders may find opportunities for partnerships or subcontracting in delivering autonomous security services aligned with evolving federal cybersecurity requirements.
When I founded XBOW in January 2024, few believed AI could truly think like a hacker and operate at machine speed. We proved it. XBOW reached the top of the HackerOne leaderboard and is now deployed at some of the most security-forward companies in the world.
