Missing Headers
Strict-Transport-SecurityHTTP Strict Transport Security is an excellent feature to support on your site and strengthens your implementation of TLS by getting the User Agent to enforce the use of HTTPS. Recommended value "Strict-Transport-Security: max-age=31536000; includeSubDomains".Note that CSP frame-ancestors is used but the value is considered too lax to substitue for XFO.
X-Frame-OptionsX-Frame-Options tells the browser whether you want to allow your site to be framed or not. By preventing a browser from framing your site you can defend against attacks like clickjacking. Recommended value "X-Frame-Options: SAMEORIGIN". Note that CSP frame-ancestors is used but the value is considered too lax to substitue for XFO.
X-Content-Type-OptionsX-Content-Type-Options stops a browser from trying to MIME-sniff the content type and forces it to stick with the declared content-type. The only valid value for this header is "X-Content-Type-Options: nosniff".Note that CSP frame-ancestors is used but the value is considered too lax to substitue for XFO.
Referrer-PolicyReferrer Policy is a new header that allows a site to control how much information the browser includes with navigations away from a document and should be set by all sites.Note that CSP frame-ancestors is used but the value is considered too lax to substitue for XFO.
Permissions-PolicyPermissions Policy is a new header that allows a site to control which features and APIs can be used in the browser.Note that CSP frame-ancestors is used but the value is considered too lax to substitue for XFO.
