How does Vercel security compare to Netlify security?

Both Vercel and Netlify provide automatic HTTPS, DDoS protection, and CDN-level security as part of their hosting infrastructure. Neither platform adds comprehensive security headers by default, requiring developers to configure them manually. Vercel offers Deployment Protection and Vercel Firewall on Pro plans, while Netlify provides password protection and role-based access control. Both platforms run serverless functions on AWS Lambda with similar isolation guarantees. The primary security differences come from developer configuration rather than platform infrastructure. UNPWNED scans applications hosted on both platforms and reports platform-specific security recommendations.
