Analysis Chains

The Analysis Chains tab displays the Root Cause Analysis and also highlights additional information which might be beneficial to the investigation.

Threat Investigations can correlate information from Endpoint Sensor, Cloud App Security, and Active Directory to display attack information about an endpoint, user account, and possible email attack vectors throughout your network.


You must properly configure Cloud App Security and Apex Central before being able to correlate email message information.

For more information, see Configuring Cloud Service Settings.



Target Endpoint

Displays details about the endpoint that was investigated

Click the endpoint name and user name to view details.

Click Isolate Endpoint to disconnect the endpoint from the network. During isolation, the agent can only communicate with the server.


After resolving the security threats on an isolated endpoint, the following locations on the Directories > Users/Endpoints screen provides options to restore the network connection of an isolated endpoint:

  • Endpoints > All: Click the name of an endpoint in the table, and click Task > Restore on the screen that appears.

  • Endpoints > Filters > Network Connection > Isolated: Select the endpoint row in the table, and click Task > Restore Network Connection.
