Is your Express app secure?

Built your Express app fast? Ship it without spending another week on security testing. Express is the default Node.js backend for AI-built apps. It's flexible — but generated Express APIs routinely ship without auth middleware, rate limiting, or input validation. Opviva is the agent that checks, proves, and fixes your Express app.

Free · no signup · we never store your source code

  • We prove vulnerabilities by reproducing them — not guesses

Common security gaps in Express apps

Missing auth middleware

Routes ship without authentication or authorization, so anyone with the URL can call privileged endpoints.

No rate limiting

Public endpoints ship without throttling, leaving them open to abuse, brute force, and runaway bills.

Unvalidated input

Handlers trust request data, opening injection, SSRF, and broken-access-control risks.

The agent that checks, proves, and fixes your Express app

  • Tell it your app’s URL — the free scan grades your live app 0–100 in seconds, no code access needed.
  • Connect GitHub and it reasons about your repo for deeper, fix-ready findings.
  • It proves each exploit is real on the Evidence Canvas, then opens the fix as a pull request you approve.
  • Turn on 24/7 monitoring and it keeps watching after launch — re-checks and uptime so new issues get caught and closed.

Express security — ask the agent

Is my Express app secure?

Not by default — generated Express APIs commonly ship without auth middleware, rate limiting, or validation. Paste your app's URL into Opviva for a free grade.

How do I secure my Express API routes?

Opviva proves which routes are reachable without auth and grades your app free, then opens fixes that add the middleware for you to approve.

Can Opviva fix security issues in an Express app?

Yes — the agent opens reviewed pull requests that add auth, rate limiting, and input validation, and you approve each one.

How do I secure my Express app?

Start with a free Opviva scan of your live Express app — it grades you 0–100 and lists exactly what's exposed. Then connect GitHub so Opviva can open reviewed pull requests that move secrets server-side, add access control, and set security headers, and turn on 24/7 monitoring so it keeps watching after launch.

Is it safe to launch a Express app to production?

Not until it's checked. AI-generated apps frequently ship with exposed keys, missing access control, and no security headers. Run Opviva's free scan first (no signup), fix what it finds, and turn on continuous monitoring so new issues are caught automatically.
