Shannon is an AI pentester that autonomously finds and executes actual exploits in your web apps, achieving 96.15% success rate on security benchmarks while you sleep

Your team ships code daily with Claude and Cursor, but your penetration test happens once a year. That’s 364 days of potentially shipping vulnerabilities to production. Shannon closes this massive security gap by acting as your autonomous AI pentester that doesn’t just scan for issues—it actually exploits them. It handles everything from complex 2FA logins to browser navigation, then delivers concrete proof of vulnerabilities with working exploits.

What sets Shannon apart is its 96.15% success rate on the hint-free XBOW benchmark and its ability to execute real attacks like SQL injection and auth bypass. Instead of drowning you in false positives, it discovered 20+ critical vulnerabilities in OWASP Juice Shop including complete database exfiltration. The AI generates pentester-grade reports with reproducible exploits, giving you the same quality assessment you’d get from hiring expensive security consultants.

With 23K+ stars and backing from Keygraph’s security platform, Shannon is perfect for development teams who want continuous security validation without the traditional overhead. One command launches a full autonomous pentest—no security expertise required on your end.
