🔒HTTP Security Headers & HSTS Generator Documentation & Guide
Web & Developer
Generate enterprise-grade HTTP security headers for Nginx, Apache, Cloudflare Pages, and Caddy. Maximize your security audit score with pre-configured Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy.
📋How to Generate Security Headers
- Select Preset or Customize: Start with our A+ Security Rating preset or customize individual security parameters.
- Choose Target Server Syntax: Select between Nginx, Apache (.htaccess), Cloudflare Pages (_headers), or Caddyfile syntax.
- Configure HSTS & Headers: Tune max-age, includeSubDomains, preload eligibility, and hardware Permissions-Policy.
- Deploy Server Block: Click 🔒 Generate Security Headers to copy ready-to-paste production directives.
⚙️Technical & Header Specifications
Defense-in-depth security headers protect visitors against man-in-the-middle, sniffing, and embedding exploits:
• HSTS Preload Eligibility: Requires a minimum max-age of 31536000 seconds (1 year), includeSubDomains, and the preload flag, qualifying your domain for browser hardcoding.
• X-Content-Type-Options (nosniff): Enforces strict MIME-type matching, preventing browsers from executing disguised image or text uploads as JavaScript.
• Permissions-Policy: Granularly disables access to sensitive browser hardware APIs (camera, microphone, geolocation, payment) across embedded frames.
💡Practical Use Cases & Best Practices
- Achieving A+ Security Ratings: Pass external compliance scans (SecurityHeaders.com, Qualys SSL Labs) with zero missing header warnings.
- Clickjacking Prevention: Enforce X-Frame-Options: DENY or SAMEORIGIN to prevent malicious websites from transparently overlaying your UI.
- Privacy Leak Prevention: Configure Referrer-Policy: strict-origin-when-cross-origin to strip sensitive URL query parameters when linking to external domains.
100% Client-Side Privacy Guarantee:All security header configurations are generated entirely client-side. Zero server environments or domain details are ever transmitted across networks.
