How Security Headers Work
Strict-Transport-Security (HSTS)
Forces browsers to use HTTPS connections, preventing man-in-the-middle attacks.
Content-Security-Policy (CSP)
Prevents XSS attacks by controlling which resources can be loaded and executed.
X-Frame-Options
Prevents clickjacking attacks by controlling if your site can be embedded in frames.
X-Content-Type-Options
Prevents browsers from MIME-sniffing files, reducing security risks.
Referrer-Policy
Controls how much referrer information is sent with requests.
Permissions-Policy
Controls which browser features and APIs can be used on your site.
