An AI pentester for your app.

From GitHub to Pull Request: it tests, proves the flaw, and brings the fix.

Connect GitHub and PreHack tests your app the way an attacker would: it finds the flaw, proves it can really be broken into, and hands you the fix, ready in a Pull Request. All you do is approve.

The most advanced AI for monitoring and fixing vulnerabilities.

Instead of spending hours installing thousands of security skills into your AI, PreHack takes it off your plate, integrated with the AI you already use.

  1. Monitors 24/7.

  2. Runs the scan on its own.

  3. Tests for real.

  4. Fixes only what it proved.

  5. Integrated through MCP.

Watches around the clock

Connected to your GitHub, PreHack follows every push and deploy and notices what changed the moment it changes.

One scan, from push to Pull Request.

app.prehack.ai

The real platform, running. Scan data is illustrative; the flow is the real one: find, prove, open the PR.

Become a Diver.

The ever-evolving PreHack community.

Your code never leaves your control.

No human ever opens your code.

Only PreHack reads the repository, on our infrastructure. No human looks at your code, and you can revoke access whenever you want.

Always one step ahead.

What keeps the tool out front is the community of Divers, who discover new vulnerabilities and bring them into PreHack.

Safety first.

PreHack's AI is never trained on your code. It's only analyzed to find flaws, never turned into training material.

AI ships vulnerabilities faster than you can review them.

This isn't us scaremongering. It's what the people who built these tools, and the ones who cover the fallout, are saying.
