Missing Headers
Feature-PolicyFeature Policy is a new header that allows a site to control which features and APIs can be used in the browser.
Warnings
Content-Security-PolicyThis policy contains 'unsafe-inline' which is dangerous in the style-src directive.
Upcoming Headers
Expect-CTExpect-CT allows a site to determine if they are ready for the upcoming Chrome requirements and/or enforce their CT policy.
Additional Information
ServerServer value has been changed. Typically you will see values like "Microsoft-IIS/8.0" or "nginx 1.7.2".
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.
Access-Control-Allow-OriginThe Access-Control-Allow-Origin header is used to configure CORS.
X-Xss-ProtectionX-XSS-Protection sets the configuration for the XSS Auditor built into older browser. The recommended value was "X-XSS-Protection: 1; mode=block" but you should now look at Content Security Policy instead.
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.

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.
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.
