Why security headers matter
Security headers are HTTP response headers that tell browsers how to behave when handling your site's content. Missing headers leave your users vulnerable to clickjacking, XSS attacks, MIME sniffing, and data injection. Most websites are missing at least 3 critical security headers. The fix is usually a few lines of configuration — but you need to know which headers are missing and what values to set for your specific platform. PageGuard checks 10 security headers, scores your security posture, and generates the exact configuration code for your hosting platform.
