Shannon
Autonomous AI that finds your vulnerabilities and exploits them — for you
The Panel's Take
Shannon is an autonomous AI security research agent from Keygraph that takes a target (web app, API, or codebase) and runs a full offensive security workflow: static analysis, attack surface mapping across OWASP Top 10, and then actual proof-of-concept exploit execution — all without manual intervention. It orchestrates real security tools (Nmap, Subfinder, SQLMap, Playwright) under the hood, not just generating reports. The Lite tier (AGPL-3.0) handles web apps and API endpoints, running browser automation and fuzzing attacks autonomously. Shannon Pro (commercial) adds SAST/SCA integration, CI/CD pipeline hooks for PR scanning, and team-level finding management. The model layer is pluggable — defaults to GPT-4o for planning with Claude Sonnet for exploit reasoning, but can be pointed at local models. What sets Shannon apart from tools like Burp Suite or ZAP is the agentic loop: it doesn't just surface a list of potential issues, it attempts exploitation and logs what worked. For small security teams and solo founders doing pre-launch security checks, this compresses days of pentesting work into a single automated run. The open-source Lite tier is the real news here — genuine autonomous exploitation capability, freely available.

“I've been paying $400/month for a pentesting retainer for pre-launch checks. Shannon Lite ran against my staging environment and surfaced an actual SQLi vulnerability in 20 minutes that my last manual audit missed. The AGPL license means I can self-host it in my CI pipeline without worrying about data leaving my network.”
“Autonomous exploitation tools have serious dual-use liability. The AGPL license doesn't prevent anyone from running Shannon against systems they don't own — and AI-generated PoC exploits at this speed are a real threat multiplier for less-sophisticated attackers. I'd want to see proper authorization checks and rate limiting baked into the Lite tier before recommending this broadly.”
“Security tooling is going through the same shift coding did with Copilot — autonomous agents are going to make pentesting accessible to every small team that currently can't afford it. Shannon is an early version of what eventually becomes a background daemon watching your entire attack surface 24/7.”
“Less relevant to my workflow directly, but I've started including 'ran Shannon against my portfolio site' in client pitches as a trust signal. The fact that indie creators can now point a professional-grade security tool at their own work without a $5K budget is a shift worth noting.”
