Why Security Headers Matter
Prevent XSS Attacks
Content-Security-Policy helps prevent cross-site scripting by controlling which resources can be loaded.
Stop Clickjacking
X-Frame-Options prevents your site from being embedded in iframes, protecting users from clickjacking attacks.
Enforce HTTPS
HSTS ensures browsers always connect over HTTPS, preventing man-in-the-middle attacks and protocol downgrades.
