Teams that want an automated pentest on every release instead of booking consultants.

Why it deserves attention

Shannon combines static analysis of your source with an agent that runs real exploits against the deployed app, so findings arrive with a reproduction instead of a pattern-match alert. It maps work to OWASP categories, runs locally from the command line with Docker, and is AGPL-3.0 with about 51,000 GitHub stars and a public benchmark against commercial tools. It needs a reachable test environment plus model API keys, and the free open-source build is whitebox-only, so plan the run and the blast radius carefully.
