Start Security ScanFrequently Asked Questions
Which platform is more secure by default?
Both have strong defaults: automatic HTTPS, DDoS protection, and isolated environments. Neither includes security headers by default - you must configure CSP, HSTS, etc. manually. The security level depends more on your configuration than the platform choice.
How do I add security headers on each platform?
Vercel: use next.config.js headers() function or vercel.json. Netlify: create a _headers file in your publish directory. Both support the same headers, just different configuration syntax.
Are preview deployments secure?
Preview deployments can expose unreleased features. Vercel offers password protection for preview URLs. Netlify has deploy previews with branch controls. Consider protecting preview deploys if they contain sensitive features or connect to production databases.
