Why HTTP Security Headers Matter More Than Most People Realize

Security headers are the cheapest, fastest, highest-ROI security improvement most websites can make. They're free, they take 5 minutes to deploy, and they block entire classes of attacks — clickjacking, MIME-sniffing, mixed content, downgrade attacks, and most cross-site scripting (XSS) damage.

The catch: there are now 7+ headers that matter, each with its own syntax, each with its own quirks. Content-Security-Policy alone has 25+ directives. Get one wrong and you either break the site or leave a hole. HSTS without preload won't protect first-time visitors. X-Frame-Options is now considered legacy in favor of frame-ancestors in CSP.

Most sites we scan are missing 4 or more critical headers. The scan tells you exactly which ones — with the exact header values to copy into your Cloudflare, Vercel, Nginx, IIS, or Apache config.

FAQ

Common questions from Omaha business owners

If you only set one, set HSTS (Strict-Transport-Security) — it forces all future connections to use HTTPS and prevents downgrade attacks. After that: Content-Security-Policy to block XSS damage, X-Content-Type-Options: nosniff to stop MIME-sniffing, and Referrer-Policy: strict-origin-when-cross-origin for privacy. The scan flags all of these.
