Unable to create a Dashboard view in CloudSOC that contains DLP policy name and statistics.
This feature is not supported by CloudSOC.
CloudSOC is cloud-based and it does not communicate with an on-prem DLP Enforce. Enforce would be the best way to obtain these reports.
Risk Analytics is a new feature introduced in Cloudsoc on 3.167, it provides many ways to analyze the data, and run summary reports. It supports the use of DLP Policy Names, either as a filter or as a dimensional variable (raw or column).
