Missing Headers
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.
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.
Permissions-PolicyPermissions 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-PolicyCross-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-PolicyCross-Origin Opener Policy allows a site to opt-in to Cross-Origin Isolation in the browser.
Cross-Origin-Resource-PolicyCross-Origin Resource Policy allows a resource owner to specify who can load the resource.
Additional Information
set-cookieThere is no Cookie Prefix on this cookie. This is not a SameSite Cookie.
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-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.
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.
