What is Shannon?
Shannon is an AI pentester that delivers actual exploits, not just alerts. Shannon’s goal is to break your web app before someone else does. It autonomously hunts for attack vectors in your code, then uses its built-in browser to execute real exploits, such as injection attacks and auth bypass, to prove the vulnerability is actually exploitable.Shannon Lite achieves a 96.15% success rate on the hint-free, source-aware XBOW Benchmark.
The Problem Shannon Solves
Thanks to tools like Claude Code and Cursor, your team ships code non-stop. But your penetration test? That happens once a year. This creates a massive security gap. For the other 364 days, you could be unknowingly shipping vulnerabilities to production. Shannon closes this gap by acting as your on-demand whitebox pentester. It doesn’t just find potential issues — it executes real exploits, providing concrete proof of vulnerabilities. This lets you ship with confidence, knowing every build can be secured.Key Features
Fully Autonomous Operation
Launch the pentest with a single command. The AI handles everything from advanced 2FA/TOTP logins to the final report with zero intervention.
Pentester-Grade Reports
Delivers a final report focused on proven, exploitable findings, complete with copy-and-paste Proof-of-Concepts to eliminate false positives.
Critical OWASP Coverage
Identifies and validates Injection, XSS, SSRF, and Broken Authentication/Authorization vulnerabilities with more types in development.
Code-Aware Testing
Analyzes your source code to intelligently guide its attack strategy, then performs live exploits on the running application.
Integrated Security Tools
Enhances discovery with Nmap, Subfinder, WhatWeb, and Schemathesis for deep analysis of the target environment.
Parallel Processing
Get your report faster with parallelized vulnerability analysis and exploitation phases running concurrently.
How It Works
Shannon emulates a human penetration tester’s methodology using a sophisticated multi-agent architecture:Reconnaissance
Builds a comprehensive map of your application’s attack surface by analyzing source code and performing live exploration via browser automation.
Vulnerability Analysis
Specialized agents for each OWASP category hunt for potential flaws in parallel, performing structured data flow analysis to trace user input to dangerous sinks.
Exploitation
Dedicated exploit agents attempt to execute real-world attacks using browser automation, command-line tools, and custom scripts to prove vulnerabilities are exploitable.
Shannon enforces a strict “No Exploit, No Report” policy. If a hypothesis cannot be successfully exploited to demonstrate impact, it is discarded as a false positive.
