Use Case

A security audit that ends with the fixes already applied

Multos reviews your application against OWASP standards, explains every finding in plain language, and generates the fix — not just a report.

One shot, first generation, built in under five minutes. No manual design pass.

What you get in the first generation

  • OWASP Top 10 review of authentication, authorization, and input handling
  • Dependency scan with upgrade paths for vulnerable packages
  • SQL injection, XSS, and CSRF checks across every input boundary
  • Secrets audit: what is exposed, where, and the safe migration path
  • Security headers and CSP configuration generated correctly
  • Rate limiting and abuse controls on authentication and expensive endpoints

Try it with a prompt like this

Audit my Express API for security issues: check authentication and session handling, SQL injection in every query, missing rate limits, exposed secrets in the repo, and generate the fixes with tests proving each one.

Paste this into Multos and you will have a working version in minutes.

Common Questions

Is this a replacement for a professional penetration test?

No — and be suspicious of any tool that claims it is. Multos catches the systematic issues (injection, broken auth, exposed secrets) that automated scanners and manual review both look for, before an engagement makes them expensive.

Does it fix issues or just report them?

It fixes them. Each finding comes with generated code changes and a test that fails before the fix and passes after — so you can verify the fix, not just trust it.

Will hardening break my existing app?

Changes are generated with the same care as features: each fix is scoped, explained, and covered by tests. Breaking changes — like invalidating old sessions — are flagged explicitly before you apply them.

How often should I run it?

After every significant change, and before any launch. Dependency vulnerabilities in particular drift over time — a quarterly pass keeps the known-vulnerability surface near zero.
