We read your code the way an attacker reads it, then we try the door. You get the exploits we could actually reproduce — with the fix — and nothing else.
We attack your code the way a real intruder would and show you only what we could actually break into — with the fix. Not a flag, a reproduced exploit.
247 maybe-problems → 1 confirmed hole
A scanner that flags hundreds of unproven "maybes" is a scanner your team has already muted — and the real one slips through with the noise. A hundred eyes that can't tell you which thing to fear are the reason you stopped looking. ArgusRed reports only what it could exploit.
"this might be vulnerable" → "here is the request and the response"
A scanner answers maybe. A real pen test answers yes — and here is exactly how. That difference is the entire product. Every finding ArgusRed shows you was reproduced against a sandbox mirroring your stack — and everything it couldn't prove, it throws away before it reaches you.
We don't surface a finding with a confidence score. We stand up an isolated sandbox with your dependencies, send the request a real attacker would, and show you the response your code gave back.
Each confirmed hole arrives with a pull request that patches it and passes your tests. Review it, merge it, and we re-attack to confirm it's actually closed.
Built on a model Cosine post-trained, not an off-the-shelf API behind a prompt. Your source and the sandbox stay in the EU. In a "is this a wrapper?" market, the lab is the proof.
One click with GitHub. Scoped access to the single repo you choose. No setup, no config, no procurement.
The agent hunts for a way in, then reproduces each candidate in a sandbox that mirrors your stack — keeping only what it could actually exploit.
A pen-test-grade report: the exploit, the request, the response — and a pull request that closes it and passes your tests.
Connect a repo and we attack it. If we can't reproduce a single real exploit, you pay nothing. When we can, you get the proof and the fix — and the report you can hand to a customer, an investor, or an auditor.
Scan my repo →ArgusRed runs on a security-tuned model Cosine post-trained — built to think like an adversary, not an off-the-shelf API behind a prompt.
Your source and the sandbox that probes it run on UK and EU servers. A plain-language data-handling answer ships with every report.
From the team behind the Cosine coding agent — the engine thousands of developers already trust to read, write, and fix real code.
