Frequently Asked Questions
What are security headers?
Security headers are HTTP response headers that tell browsers how to handle your content. They protect against attacks like XSS, clickjacking, and MIME confusion.
What is Content Security Policy (CSP)?
CSP is a security header that controls which resources browsers can load. It prevents XSS attacks by blocking unauthorized scripts from executing on your page.
Do I need all security headers?
While not all headers are mandatory, implementing key headers like CSP, HSTS, and X-Frame-Options significantly improves security. We prioritize recommendations by impact.
Will adding security headers break my site?
Some headers like CSP can break functionality if misconfigured. We recommend using report-only mode first and testing thoroughly. Our tool identifies potential issues.
