Get started with the data loss prevention Alerts dashboard
Microsoft Purview Data Loss Prevention (DLP) policies can take protective actions to prevent unintentional sharing of sensitive items. When an action is taken on a sensitive item, you can be notified by configuring alerts for DLP. This article shows you how to define rich alert policies that are linked to your data loss prevention (DLP) policies. You'll see how to use the DLP alert management dashboard in the Microsoft Purview compliance portal to view alerts, events, and associated metadata for DLP policy violations.

DLP alert configuration
To learn how to configure an alert in your DLP policy, see Configure and view alerts for data loss prevention policies.
Your organization's audit log retention policy configuration controls how long an alert remains visible in the console. See, Manage audit log retention policies for more information.
Aggregate event alert configuration
If your organization is licensed for aggregated alert configuration options, then you'll see these options when you create or edit a DLP policy.
This configuration allows you to set up a policy to generate an alert every time an activity matches the policy conditions or when a certain threshold is exceeded, based on the number of activities or based on the volume of exfiltrated data.
Single event alert configuration
If your organization is licensed for single-event alert configuration options, then you'll see these options when you create or edit a DLP policy. Use this option to create an alert that's raised every time a DLP rule match happens.
