LOCAL · READ-ONLY · NOTHING LEAVES YOUR MACHINE

Find the hole before the hackers do.

You shipped your app in a weekend with AI. SENTINEL scans your code, live sites and databases for exposed secrets, open databases and known vulnerabilities, before someone else finds them first.

The problem
You shipped fast.
Bots scan public code every minute.
One live key can drain your account before you refresh.

AI tools like Lovable, Cursor and v0 are built for speed, not for catching the API key you pasted into a file, the Supabase table left open to the world, or the npm package shipping a known CVE. Attackers automate the search. You need to find it first.

One command

Watch it work.

Point SENTINEL at a project, a URL or a database. It runs every check in order, read-only, and hands back exactly what is exposed and how to fix it.

What it finds

Four ways your app leaks, covered.

🔑

Exposed secrets

Twelve signatures for Stripe, AWS, OpenAI, Google, Slack, SendGrid, Twilio, JWTs and more, plus a generic high-entropy detector. It even reads your git history for keys you already deleted.

🗄️

Open databases

Live, read-only checks on Supabase and Firebase for data anyone can read without signing in. MySQL, SQL Server and MongoDB are reviewed from the connection string alone, never connected to.

📦

Vulnerable dependencies

Your packages cross-checked against the live OSV.dev vulnerability feed, with the exact version that fixes each one. No more shipping a library with a known hole.

🔒

Private by design

Every check is read-only. No SQL injection, no blind writes, no port scanning. Your code and secrets never leave the machine. Only package names are sent to OSV to check for vulnerabilities.

The promise

Read-only. Local.
Nothing leaves your machine.

A security tool that uploads your code is just another place to get breached. SENTINEL runs entirely on your computer, so the thing that finds your secrets never becomes the thing that holds them.
