summary for non-techies**
Microsoft Purview's new User-Based Alert Aggregation feature for Data Loss Prevention allows security teams to group multiple alerts by user within a set time window, simplifying the process of identifying patterns and potential insider threats by focusing on overall user behavior rather than individual alerts.
Direct effects for Operations**
Increased Alert Volume
The aggregation of alerts may lead to an increase in the total number of alerts generated, complicating the monitoring process for security teams.
