Frequently Asked Questions

Which security headers are most critical to implement?

The most critical headers are Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), and X-Frame-Options. These prevent major attack vectors like man-in-the-middle attacks, XSS, and clickjacking.

How do I implement these headers in my web server?

Headers can be set at multiple levels: web server (nginx, Apache), application framework (Express.js, Django), or CDN/proxy (CloudFlare, AWS). The tool provides specific examples for each header.

What is a good security score to aim for?

Aim for a score of 85+ (Grade A-) for production applications. Critical applications should target 90+ (Grade A+). The score considers both header presence and proper configuration.

How often should I review security headers?

Review security headers quarterly or after major application changes. Subscribe to security bulletins for new header recommendations and browser updates that might affect your configuration.

Can security headers break my application?

Yes, particularly CSP and frame-related headers. Always test in a development environment first. Start with CSP in report-only mode to identify issues before enforcing.
