SentinelOS is a local-first AI security platform that finds, proves, and fixes the vulnerabilities that AI coding tools leave behind — and enforces hard rules that an AI agent cannot override.
Point it at any public GitHub repo. It scans for leaked secrets, unsafe code, risky dependencies, and prompt injection, then does what scanners can't: it spins up a throwaway copy inside a locked Docker sandbox and attacks the running app for real — SQL injection dumps the admin table, prompt injection makes an AI endpoint leak its secret. Every verdict comes from the actual HTTP response, never the model's claim. It then patches the code, rebuilds, and re-attacks to prove the fix holds, and git-blames each bug to the exact commit — flagging the ones written by an AI.
The core design: the LLM only reasons and plans. A deterministic Policy Engine decides what may run, and a Verification Engine decides whether a fix actually worked. When the AI tries to edit a protected file, the rules block it — the guardrail that was missing when an AI agent wiped a company's production database this year.
It runs entirely on your machine; your code never leaves. Live demo:
