Warnings
Referrer-PolicyThe "origin-when-cross-origin" value is not recommended.
X-Frame-OptionsThere was a duplicate X-Frame-Options header.
X-XSS-ProtectionThere was a duplicate X-XSS-Protection header.
X-Content-Type-OptionsThere was a duplicate X-Content-Type-Options header.
Content-Security-PolicyThis policy contains 'unsafe-inline' which is dangerous in the default-src directive. This policy contains 'unsafe-eval' which is dangerous in the default-src directive. The CSP directive default-src contains default-src as a source expression. Should this be "default-src ...; default-src ..." instead?
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 should be removed or the value changed.
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".
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.
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 is a new header that allows a site to control which features and APIs can be used in the browser.

X-WebKit-CSPX-Webkit-CSP is required for CSP support in older Chrome, Safari and other Webkit based browsers. For other modern browsers the Content-Security-Policy header should be used.
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.

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.
