A cleansed site with fail and warnings...

See: https://asafaweb.com/Scan?Url=truparportal.azurewebsites.net
Custom errors are easy to enable, just configure the web.config to ensure the mode is either "On" or "RemoteOnly" and ensure there is a valid "defaultRedirect" defined for a custom error page as follows:

<customErrors mode="RemoteOnly" defaultRedirect="~/Error" />

It looks like a cookie is being set without the "HttpOnly" flag being set (name : value):

Unless the cookie legitimately needs to be read by JavaScript on the client, the "HttpOnly" flag should always be set to ensure it cannot be read by the client and used in an XSS attack. -> http://www.domxssscanner.com/scan?url=http%3A%2F%2Ftruparportal.azurewebsites.net ->
