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
ServerThis Server header seems to advertise the software being run on the server but you can remove or change this value.
X-Powered-ByX-Powered-By can usually be seen with values like "PHP/5.5.9-1ubuntu4.5" or "ASP.NET". Trying to minimise the amount of information you give out about your server is a good idea. This header seems to have been altered to remove such information, but could still be removed.
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-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".
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".
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.
Content-Security-Policy-Report-OnlyContent Security Policy Report Only is used to test a Content Security Policy before making it live. The browser will report on actions that would have been taken based on the policy. Analyse this policy in more detail.
Access-Control-Allow-OriginThis is a very lax CORS policy. Such a policy should only be used on a public CDN.
