Common issues with Symantec CloudSOC integrated with Symantec Cloud SWG service.
Environment
CloudSOC.
CASB.
Cloud SWG.
Resolution
Office 365: Some Outlook applications enter an infinite authentication loop accessing Office 365 tenants that use federated authentication. Exchange does not have the “Modern Authentication” feature enabled.
General:
Cloud SWG will intercept SSL for any CloudSOC domain of interest by default, unless an explicit 'do not SSL intercept' rule exists for the CloudSOC domain.
In this later case, the Cloud Proxy will not forward traffic into CloudSOC and policies applying there for the gatelet will not apply.
The Cloud SWG DLP scanning policy may override CASB Gatelet routing.
Dropbox: The Dropbox application fails to connect when the Dropbox Gatelet is enabled.
An incompatibility with the Dropbox application and SSL interception causes the problem.
Web browser access to Dropbox functions properly.
Zoom:
Desktop Application support is limited to allow/deny access (Access Enforcement Policy)
Web browser for Zoom works as expected. However, see article below regarding steps needed to enable Zoom Gatelet.
