Missing Headers

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.

Warnings
Content-Security-PolicyThis policy contains 'unsafe-inline' which is dangerous in the script-src directive. This policy contains 'unsafe-eval' which is dangerous in the script-src directive.
Additional Information
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".
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.
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.
public-key-pins-report-onlyHTTP Public Key Pinning Report Only allows a host to test the effects of a HPKP policy before making it live. The browser will report on actions that would have been taken if the policy were live so a host can see what effect it would have. Analyse this policy in more detail.
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".
