Missing Headers
| Content-Security-Policy | Content 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. |
|---|---|
| X-Frame-Options | X-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. Recommended value "X-Frame-Options: SAMEORIGIN". |
| Permissions-Policy | Permissions Policy is a new header that allows a site to control which features and APIs can be used in the browser. |

Upcoming Headers
| Cross-Origin-Embedder-Policy | Cross-Origin Embedder Policy allows a site to prevent assets being loaded that do not grant permission to load them via CORS or CORP. |
|---|---|
| Cross-Origin-Opener-Policy | Cross-Origin Opener Policy allows a site to opt-in to Cross-Origin Isolation in the browser. |
| Cross-Origin-Resource-Policy | Cross-Origin Resource Policy allows a resource owner to specify who can load the resource. |
Additional Information
| server | Server value has been changed. Typically you will see values like "Microsoft-IIS/8.0" or "nginx 1.7.2". |
|---|---|
| strict-transport-security | HTTP 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. |
| referrer-policy | Referrer 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-content-type-options | X-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-by | X-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. |
