### TL;DR

Shannon is a fully autonomous AI-powered penetration testing tool developed by KeygraphHQ, designed to identify actual exploits in web applications. It autonomously hunts for attack vectors in your code, then uses its built-in browser to execute real exploits, such as injection attacks and authentication bypasses, to prove the vulnerability is actually exploitable. Shannon has achieved a 96.15% success rate on the hint-free, source-aware XBOW Benchmark.
