Frequently Asked Questions

Why do I need security headers?
Modern browsers respect security headers to defend against XSS, clickjacking, MIME-sniffing, mixed content, and more. Properly configured: A+ on securityheaders.com (Scott Helme). Bad config: A or worse, exploitable. Site running without security headers in 2026 is asking for trouble.
CSP — too strict or too loose?
"unsafe-inline" + "unsafe-eval" defeat XSS protection. Strict CSP requires nonce or hash for inline scripts — work, but right move. Most starter CSPs are too loose (defeat purpose). Modern frameworks (Astro, Next.js) emit nonces; use them.
HSTS preload — should I?
HSTS = Strict-Transport-Security. Preload list = browsers force HTTPS even on first visit. ONLY add to preload list when 100% sure all subdomains support HTTPS. Removal from preload list takes weeks. Start: max-age=31536000 (1 year), no preload. Add preload after 1 month verified.
