Introduction

XBOW attacks applications and APIs the way an elite attacker would and reports only what it actually broke into. Every finding includes the working exploit, the request and response and steps to reproduce; findings in generally available vulnerability classes are confirmed by a deterministic check, and preview classes are labelled. When your team deploys a fix, XBOW re-tests it.

Its track record is cited on the homepage: it ranked #1 on HackerOne above every human researcher, found three critical Microsoft CVEs on its own and appears on Microsoft’s MSRC leaderboard. In October 2026 an XBOW researcher working with agents chained three unknown Chrome bugs into a full sandbox escape in six days, earning Google’s first $250,000 full-chain reward of the year.

Thousands of agents test in parallel and chain flaws into working attacks. It runs continuously or on demand and returns first findings in hours; one Fortune 50 organisation assessed 180 applications in a month and received 1,216 validated findings.

Features

1. Validated exploits: Working exploit with every finding.
2. Deterministic confirmation: GA classes confirmed by checks.
3. Massive parallelism: Thousands of agents at once.
4. Attack chaining: Combines flaws into real attacks.
5. Fix re-testing: Confirms patches work.
6. Ticketing integration: Findings land in your tracker.

Pros

1. Proven results: Third-party scored track record.

Cons

1. Enterprise pricing: No public plans.
2. Black-box focus: Less code-level guidance than white-box tools.
