Secure HTTP Headers Generator

Server Security

Generate security HTTP headers like CSP, HSTS, and X-Frame-Options. Improve your website security configuration.

Enforce HTTPS connections.

Prevent clickjacking attacks (DENY/SAMEORIGIN).

Prevent MIME type sniffing (nosniff).

Control how much referrer info is sent.

Disable camera, mic, geolocation.

Configuration
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;
add_header X-Frame-Options "SAMEORIGIN" always;
add_header X-Content-Type-Options "nosniff" always;
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
add_header Permissions-Policy "camera=(), microphone=(), geolocation=()" always;

What is This Tool?

A secure HTTP headers generator creates security-focused HTTP response headers for web applications. Configure Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and other security headers that protect against XSS, clickjacking, and other web attacks.

Security headers are a critical defense layer: CSP prevents XSS by controlling allowed script sources, HSTS forces HTTPS, X-Frame-Options prevents clickjacking, and X-Content-Type-Options stops MIME sniffing. Major security scanners (Mozilla Observatory, SecurityHeaders.com) check for these headers.

Common Use Cases

Security Hardening

Generate a complete set of security headers to achieve A+ ratings on Mozilla Observatory and SecurityHeaders.com.

CSP Development

Build Content-Security-Policy headers incrementally, adding sources as needed while maintaining strong security defaults.

Compliance

Meet PCI-DSS, OWASP, and SOC 2 requirements for HTTP security headers in web applications.

Server Configuration

Generate header configurations for Nginx, Apache, Express.js, and CDN providers.

Frequently Asked Questions

Which headers are essential?

Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Permissions-Policy.

Will security headers break my site?

CSP can break functionality if too restrictive. Start with report-only mode (Content-Security-Policy-Report-Only) to identify issues before enforcing.

Where do I add these headers?

Server config (Nginx/Apache), application middleware (Express/Django), CDN settings (Cloudflare/AWS), or meta tags (limited subset).
