Frequently Asked Questions

What are security headers?

Security headers are HTTP response headers that instruct browsers on how to behave when handling your site's content. They help prevent security vulnerabilities like XSS, clickjacking, and protocol downgrade attacks.

Why are security headers important?

Security headers provide an additional layer of protection for your website. They help prevent common attacks, protect user data, and improve your site's overall security posture. Modern browsers enforce these headers to keep users safe.

Which security headers should I implement?

Essential security headers include: Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options, X-XSS-Protection, and Referrer-Policy. Each serves a specific security purpose.

How does the security score work?

Our tool analyzes 8+ security headers and assigns points based on their presence and configuration. A score of 90-100 is excellent, 70-89 is good, 50-69 is fair, and below 50 needs improvement.
