What report provides a count of DLP policy matches over time on an item level within Microsoft 365?

The DLP incidents report is specifically designed to provide detailed insights into data loss prevention (DLP) policies by tracking incidents over time at an item level. This report captures matches against the policies established within an organization, offering a comprehensive view of when and where these policies are triggered. It helps administrators to monitor compliance with DLP strategies and understand the frequency of violations, which can inform future policy adjustments.

This report plays a crucial role in helping organizations identify trends in data protection issues, evaluate the effectiveness of existing DLP policies, and assess potential risks associated with data handling practices. By providing item-level details, it allows for deeper analysis and enables organizations to take proactive measures in response to recurring incidents.

In contrast, the other reports listed do not focus on item-level DLP policy matches. The DLP data breach report is primarily concerned with breaches that have occurred, the Microsoft compliance report encompasses a wider scope of compliance metrics and doesn't drill down into the specifics of DLP incidents, while the DLP user accountability report focuses on tracking user interaction with DLP policies rather than providing a count of matches over time.
