What it is

Shannon reads a web application's source code to spot likely attack paths, then drives a browser and shell tools to launch real exploits against the live app and its APIs, reporting only the vulnerabilities it managed to confirm. Security teams and developers run it from the command line or in CI/CD to test staging environments and releases between formal pentests. Results can be exported as SARIF, and it works with hosted or local models via your own keys.
