What are Netlify security best practices?

Short Answer

Key Netlify security practices: enable database security, use environment variables for secrets, add security headers, and scan before launch.

Detailed Answer

Follow these Netlify security best practices:

**1. Database Security** Enable and configure Row Level Security (Supabase) or Security Rules (Firebase). Test by querying as an unauthenticated user.

**2. Secret Management** Never hardcode API keys. Use environment variables and keep secrets server-side only.

**3. Authentication Hardening** - Require email verification - Set minimum password requirements - Implement rate limiting

**4. Security Headers** Configure CSP, HSTS, X-Frame-Options, and other headers in your hosting platform.

**5. Regular Scanning** Use VAS to scan your app before launch and after major changes.

Expert Perspectives

Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.

The problem with AI-generated code isn't that it doesn't work - it's that it works just well enough to ship, but contains subtle security flaws that are hard to spot.
