Microsoft Purview: Data Loss Prevention - User Based Aggregation of DLP Alerts

🚨 The Signal: Microsoft Purview DLP now aggregates alerts by user, even across multiple rules. This reduces alert fatigue and streamlines investigations by consolidating related incidents into a single, contextual alert.

The Impact

Security teams are affected by reduced alert noise, improving incident response efficiency and reducing the risk of missed critical alerts.

• Security Teams: Reduced alert volume, improving focus on critical incidents.
• DLP Administrators: Streamlined investigation process, saving time and effort.
• Compliance Officers: Better contextual understanding of policy violations, aiding reporting.

The Action

1. Review existing DLP policies to understand how aggregation will affect current alert volumes.
2. Familiarise security operations centre (SOC) staff with the new aggregated alert format in the Microsoft Purview compliance portal.
3. Update incident response playbooks to leverage the enhanced context provided by user-based alert aggregation.
