Standards-mapped validation
From a live app to shareable proof.
StackAttest maps evidence from your live app, source, dependencies, and runtime to OWASP ASVS 5, NIST SSDF, CWE, OWASP API Security Top 10, WSTG, SLSA. The result is a Passport that shows what was checked, how strongly it was proven, and what to do next.
Connect your product
Point us at a live production URL, or connect a repository with a read-only app. We never write to your code during validation, and nothing about your product becomes public until you decide it should.
We gather graded evidence
Deterministic checks inspect your live surface, source, dependency graph, and isolated runtime against controls mapped to OWASP ASVS 5, NIST SSDF, CWE, OWASP API Security Top 10, WSTG, SLSA. Every control records how it was proven, from inference through runtime verification.
A 6-model council challenges it
The intended lineup spans OpenAI, Anthropic, Google, xAI, DeepSeek, Mistral. Each run reports which configured reviewers answered, their agreements and objections, and any minority opinions. Consensus never changes the deterministic score.
You get four honest signals
Instead of one number that hides the details, you get the Score, Evidence Coverage, Validation Confidence, and AI Consensus. Together they tell you not just the result, but how much to trust it.
Follow a founder action plan
Your findings become a ranked weekly action plan. For supported fixes, StackAttest can open a reviewable pull request. Nothing merges without your approval, and a new validation updates your Passport.
Share the right proof
Publish a Passport with verified capabilities, events, and embeddable badges, or grant selected due-diligence sections to an investor with access you can expire or revoke. The questionnaire assistant can draft answers from verified evidence.
Climb from L0 to L5
The verification ladder records progress from registration through external, code, runtime, production, and continuous validation. Each rung requires stronger evidence than the one before it.
