The Google Security Operations (SecOps) SOAR platform provides a native feature to enforce data collection at the end of an incident's lifecycle. The most effective and standard method to ensure analysts "must be categorized" is to customize the Close Case dialog.

This built-in feature allows an administrator to modify the pop-up window that appears when an analyst clicks the "Close Case" button in the UI. For this use case, the administrator would add a new custom field, such as a dropdown list titled "DLP Root Cause." This field would then be populated with the "five DLP event types" as the selectable options.

Crucially, this new field can be marked as mandatory. This configuration forces the analyst to select one of the five predefined root causes before the case can be successfully closed. This method ensures 100% compliance with the requirement, captures structured data for later reporting and metrics, and is the standard, low-maintenance solution. Using tags (Option B) is not mandatory and is prone to human error. Customizing the case name (Option A) is not a structured data field and is not enforceable.
