Xbow

XBOW transforms application security with AI-powered continuous offense. Built by the creators of GitHub Copilot and GitHub Advanced Security, we're redefining how organizations think about offensive security.

High-Level Overview

XBOW is an AI-powered offensive security company that automates penetration testing and dramatically accelerates the discovery of vulnerabilities and exploits across all types of software. The company’s platform deploys hundreds of autonomous AI agents to simulate real-world hacking scenarios, delivering human-level security testing at machine speed. XBOW serves organizations seeking to secure their applications and infrastructure at the pace of modern development, offering continuous, scalable, and comprehensive offensive security coverage. Its technology is particularly valuable for enterprises, startups, and security teams that need to validate every update and application quickly, without the bottlenecks of manual pentesting.

XBOW has rapidly gained traction in the cybersecurity ecosystem, making history as the first AI to top the U.S. HackerOne bug bounty leaderboard and discovering over 1,000 vulnerabilities—including zero-days—across major platforms. Its growth momentum is fueled by strong industry recognition, a proven ability to reduce false positives through autonomous exploitation and validation, and seamless integration with leading bug bounty platforms.

Origin Story

XBOW was founded by Oege de Moor, a former leader of GitHub Next (the research and development division behind GitHub Copilot and GitHub Advanced Security), alongside a team of experts in security, artificial intelligence, and scalable systems. The idea emerged from the growing gap between the speed of software development and the pace of traditional security testing. Recognizing that manual pentesting could not keep up with the velocity of modern software releases, the founders set out to build a platform that could automate offensive security at scale.

Early traction came quickly: XBOW’s AI agents began outperforming elite human hackers on the HackerOne leaderboard, validating the platform’s effectiveness and drawing attention from both the cybersecurity and investment communities. The company’s breakthrough moment—topping the HackerOne leaderboard—cemented its reputation as a pioneer in AI-driven offensive security.

Core Differentiators

• Autonomous AI Agents: Hundreds of specialized AI agents work in parallel, simulating the tactics of skilled human hackers to discover, validate, and exploit vulnerabilities without human intervention.
• Human-Level Testing at Machine Speed: Delivers comprehensive pentesting results in hours, not weeks, enabling security teams to keep pace with rapid development cycles.
• Continuous and Scalable Coverage: Tests every endpoint and attack vector across multiple targets simultaneously, removing resource constraints and capacity limits.
• Battle-Tested Intelligence: Trained by top hackers and proven in real-world environments, with over 1,000 vulnerabilities discovered, including zero-days.
• Reduced False Positives: Unlike basic scanners, XBOW autonomously validates findings through real exploitation, providing proof-of-concept exploits and actionable insights.
• Seamless Integration: Integrates with bug bounty platforms like HackerOne, streamlining submission and prioritization of findings for security teams.

Role in the Broader Tech Landscape

XBOW is riding the wave of AI-driven automation in cybersecurity, a trend accelerated by the increasing complexity and velocity of software development. As organizations adopt DevOps and continuous delivery, the need for security testing that matches development speed has never been greater. XBOW’s technology addresses this critical gap, enabling companies to secure their digital assets without slowing down innovation.

The timing is pivotal: with the rise of AI-powered attacks and the growing sophistication of cyber threats, organizations must “fight fire with fire” by leveraging AI for defense. XBOW’s platform not only helps companies stay ahead of attackers but also shifts the balance in the bug bounty and pentesting ecosystem, sparking industry-wide discussions about the future role of AI in cybersecurity.

Quick Take & Future Outlook

XBOW is poised to redefine offensive security, making AI-powered pentesting a standard practice for organizations of all sizes. As AI continues to evolve, XBOW’s influence will likely expand beyond vulnerability discovery into broader areas of security automation, such as red teaming, threat intelligence, and proactive defense. The company’s success signals a broader shift in the cybersecurity landscape—one where AI and human expertise work in tandem to secure the digital world.

Just as GitHub Copilot transformed software development, XBOW is transforming how we think about security testing: not as a bottleneck, but as an enabler of innovation. The future of offensive security is automated, continuous, and powered by AI—and XBOW is leading the charge.
