Enable SSL interception for https://portal.threatpulse.com in order to show the proper status and additional details.
To validate if the site is being intercepted or not, check the padlock on the URL and look at the certificate. If the certificate isn't the Cloud Root CA, but the egress IP addresses match the IP addresses found in article 167174, then you are protected but just not doing SSL interception on that site.
