Missing Headers
Permissions-PolicyPermissions Policy is a new header that allows a site to control which features and APIs can be used in the browser.
Additional Information
ServerThis Server header seems to advertise the software being run on the server but you can remove or change this value.
Expect-CTExpect-CT allows a site to determine if they are ready for the upcoming Chrome requirements and/or enforce their CT policy.
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-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".
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. You can sign up for a free account on Report URI to collect reports about problems on your site.
Access-Control-Allow-OriginThe Access-Control-Allow-Origin header is used to configure CORS.
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.
Feature-PolicyFeature Policy has been renamed to Permissions Policy, see the details here.
X-Frame-OptionsThe XFO header was not sent but frame-ancestors in Content Security Policy was used instead.
