Cloud-to-On-Premise Evidence Synchronization

 icons.png Watch an interactive demo about Synchronize Evidence from Cloud to On-Premise 

When a DLP Policy is triggered, a copy of the item that caused the trigger can be saved as evidence and synchronized to Trellix ePO. To manage the amount of evidence data synchronized, you can use the "Save Evidence" response in DLP Policy. Using this option enables you to select which policies synchronize evidence and can help reduce the amount of unwanted data saved to ePO.

Before You Begin

To synchronize evidence files to Trellix ePO, make sure to follow the below steps in order:

  1. On the Policy > Policy Settings > Enterprise DLP > Security Service Edge DLP tab, enable Send evidence files to Trellix ePO toggle button. To configure these options on the Enterprise DLP page, see Configure Enterprise DLP.

NOTE: If the Send evidence files to Trellix ePO toggle button is disabled, the Save Evidence response action will not be visible on the DLP Policies page.

A new DLP Policy has been created and saved on the DLP Policies page. When the DLP Policy is evaluated and its rules are matched, policy incidents are triggered and evidence files from Skyhigh CASB will be saved and made available for synchronization to Trellix ePO. Evidence will be copied when the ePO server incident and evidence tasks are run.
