FAQ

Questions, answered

No. Mitsumono is a post-production scanner — paste your live URL and the crew works from the deployed site, the client bundle, and your backend's public API. Nothing to install, no GitHub OAuth.

Backend fingerprinting (Supabase/Firebase/custom), Row Level Security and anonymous read access, exposed API keys and secrets in the client bundle, missing auth checks and rate limits, and CORS/security headers.

Most tools just list what's broken. Mitsumono's Fixer turns every finding into a ready-to-paste AI prompt — with an explanation — so you can hand it straight to Cursor, Claude, or Copilot and ship the fix.

Yes. Every check is read-only and non-destructive — we test with anonymous requests the same way a real attacker would, but we never write, modify, or delete your data.

Yes — ask follow-up questions about any finding, request a re-scan after you ship a fix, or have the Fixer walk you through a prompt in plain language.

Scout still fingerprints your backend and runs the checks that apply — auth, rate limits, headers, and CORS work regardless of what's powering your app.

Stop shipping vulnerabilities. Start shipping safe.

Your app is already live and already exposed. The difference is whether you find out from us, or from an attacker.
