ℹ️ About HTTP Security Headers

Strict-Transport-Security (HSTS) forces browsers to use HTTPS. Content-Security-Policy (CSP) prevents XSS attacks by controlling which resources can load. X-Content-Type-Options stops MIME-type sniffing. X-Frame-Options blocks clickjacking by preventing iframe embedding.

mercari.com's security score of 60/100 reflects how many of these protective headers are configured. Higher scores indicate better defense against common web attacks.
