Unified Alert Grouping combines Content-Based Alert Grouping and Intelligent Alert Grouping with a flexible time window for increased precision and correlation control. Unified Alert Grouping will group alerts when alert content matches and Intelligent Alert Grouping determines alerts are similar. Alerts will group only when both conditions are satisfied.
