Additional Information
ServerThis Server header seems to advertise the software being run on the server but you can remove or change this value.
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.
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.
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".
X-XSS-ProtectionX-XSS-Protection sets the configuration for the cross-site scripting filters built into most browsers. The best configuration is "X-XSS-Protection: 1; mode=block".
Access-Control-Allow-OriginThis is a very lax CORS policy. Such a policy should only be used on a public CDN.
Content-Security-PolicyContent Security Policy is an effective measure to protect your site from XSS attacks. By whitelisting sources of approved content, you can prevent the browser from loading malicious assets. Analyse this policy in more detail.
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.
Expect-CTExpect-CT allows a site to determine if they are ready for the upcoming Chrome requirements and/or enforce their CT policy.
