If a TLS root certificate has not been installed and a user visits an HTTPS-enabled website that is blocked by a policy, their browser will return a certificate error page instead of a WebTitan block page. This can be confusing for the user. To avoid this, download and import the WebTitan TLS root certificate.
Follow these steps to download and import a .pem WebTitan TLS root certificate to Google Workspace.
Replace my.webtitancloud.com with your WebTitan Cloud URL in the following URL: http://my.webtitancloud.com:8080/ssl/ca.pem
Navigate to the updated URL and a certificate file, ca.pem, automatically downloads. Take note of the location of this file on your computer.
Log into your Google Workspace account.
From the main menu go to Devices > Network > Certificates.
Select the OU you want this certificate to be available to. A child OU inherits settings from its parent OU, so in the example below if a certificate is added to OTG-DocsTest-Chromebook it will be inherited by OTG-Students and OTG-Teachers.
Click ADD CERTIFICATE.
Click Upload and select the certificate downloaded in Step 2 above. Click Open.
