Your site could be at risk, let’s perform a deeper security analysis of your site and APIs:
Missing Headers
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. Recommended value "Strict-Transport-Security: max-age=31536000; includeSubDomains".
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
serverThis Server header seems to advertise the software being run on the server but you can remove or change this value.
set-cookieThere is no Cookie Prefix on this cookie.
x-aspnetmvc-versionX-AspNetMvc-Version details further information about your ASP.NET MVC version and should be removed.
x-aspnet-versionX-AspNet-Version details specific information about your ASP.NET version and should be removed.
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. You can sign up for a free account on Report URI to collect reports about problems on your site.
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-OptionsThe XFO header was not sent but frame-ancestors in Content Security Policy was used instead.
