Why Peak
The model is the easy part.
Anyone can point an AI model at a product. We built what it takes to break in and prove it.
9.0/10CVSS 4.0, or it isn't critical
Agents derive a CVSS 4.0 vector from the proven behavior. A separate calculator scores it. Below 9.0, they keep hunting.
Logsbehind every finding
Every finding traces to the raw request and response, and each run is archived before its machine shuts down. We prove a break with one protected record, then stop.
80tools per run
Each run gets its own isolated machine, with everything from sqlmap to Frida and Ghidra installed.
New surfaceafter every proof
Agents can't re-prove a bug or farm variants of it. Once a surface is proven they leave it and attack a different part of your architecture.
0scanner output in your report
A person reproduces each issue. CORS notes, version banners and public metadata get thrown out before they reach you.
28,155pentests and counting
Read what the teams we reported to said about them further down.
How it works
Every finding is reproduced by hand.
Scope, test accounts and a stop contact are agreed before anything runs.
Step 1 / Hunt
AI hunts for real routes.
Agents work through the agreed parts of your product for hours, each run on its own isolated machine.
Step 2 / Prove
A person proves it.
Each claim traces to raw evidence. What doesn't hold is corrected, downgraded or dropped.
Step 3 / Retest
Then we try again.
Your team makes the change. We retest each finding and its direct bypasses, then record the result. We never touch your code.
