ArgosX vs VibeArmor
Both scan the app you deployed, no source code needed. The difference is proof. VibeArmor gives you an AI grade. ArgosX authenticates a second distinct account, proves cross-user data access with the exact request and response, and can escalate to a human expert before you ship.
GET /api/account- Account A
GET /api/account200 · returns A's own record - Account B · different login
GET /api/account200 · returns A's record (email, API token) - Anonymous
GET /api/account401 · denied
The endpoint has a login, it just doesn't check whose data it returns. An AI-only scanner sees a 200 and moves on. ArgosX authenticated a second account and proved the read.

Proof beats a grade
A letter grade tells you something might be wrong. A two-actor replay shows account B reading account A's record. One is a warning, the other is evidence you can act on.
A human, without the pentest price
Our hand-verified tier is $249, where a traditional human pentest runs into the thousands. No gimmicks: a clean result from an independent checker is the value, so we do not promise refunds for finding nothing.
The independent second opinion
As the builder platforms ship their own scanners, the real question becomes who checks that the fix actually holds. That is the job ArgosX is built for.
