Issue/Introduction

Common issues with Symantec CloudSOC integrated with Symantec Web Security Service (WSS).

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: The WSS 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.
