Vercel Deployment Launch Security Checklist

TL;DR

Vercel handles HTTPS and infrastructure security, but you need to configure environment variables correctly, add security headers, review team access, and verify your app's auth works in production. This checklist covers Vercel-specific settings plus deployment verification.

Environment Variables 4

Set all production env varsGo to Project Settings > Environment Variables. Add all required vars.

Use different values for Production/Preview/DevProduction should use real keys. Preview can use test keys.

Verify NEXT_PUBLIC_ prefixesOnly public-safe values should use this prefix

Check sensitive variables aren't loggedReview build logs for accidentally exposed secrets

Security Headers 4

Add security headers in vercel.json or next.config.jsX-Frame-Options, X-Content-Type-Options, Referrer-Policy

Configure Content Security PolicyStart restrictive and loosen as needed for your dependencies

Verify HTTPS redirectVercel handles this, but test that http:// redirects

Check headers with securityheaders.comVerify your headers are configured correctly

Access and Team 3

Review team member accessRemove people who no longer need access

Enable Deployment Protection (if needed)Require authentication to view preview deployments

Review Git integration permissionsCheck what Vercel can access in your repo

Production Verification 3

Test on production URLDon't just test previews. Test the actual production domain.

Verify authentication worksLogin, protected routes, and sessions work correctly

Run automated security scanCatch issues you may have missed

Is Vercel secure for production?

Vercel is highly secure for production deployments with automatic HTTPS, DDoS protection, and secure infrastructure. Your main responsibilities are configuring environment variables correctly, adding security headers, and ensuring your application code is secure.

How do I add security headers on Vercel?

For Next.js, add headers in next.config.js. For other frameworks, use vercel.json. You can configure X-Frame-Options, CSP, and other security headers in either location.
