Set max-age to at least 31536000 (1 year). - **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'. - **[PASS]** X-Frame-Options is properly configured - **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests. Set to 'strict-origin-when-cross-origin' or stricter. - **[WARNING]** Permissions-Policy header is missing — Controls which browser features (camera, microphone, geolocation) are allowed. Set it to restrict unused features. - **[CRITICAL]** Content-Security-Policy header is missing — CSP is the most important header for preventing XSS attacks.
