Microsoft Purview Data Loss Prevention (DLP) is designed to “detect and protect sensitive items” across Microsoft 365 locations, endpoints, and cloud apps. Microsoft explains that Purview DLP policies use sensitive information types, exact data match (EDM), and machine learning–based trainable classifiers to identify content, and then automatically apply protective actions such as blocking or restricting sharing, notifying users with policy tips, auditing, or auto- quarantining/justifying activities. This fulfills the description “use machine learning algorithms to detect and automatically protect sensitive items.” While eDiscovery focuses on legal hold and content discovery, and Communication compliance monitors communications for policy violations (ethics/regulatory scenarios), they are not positioned to broadly and automatically protect sensitive data across services. “Information risks” is not a distinct Purview solution category. Therefore, the Purview capability that leverages machine learning classifiers and automatically enforces protections on sensitive data is Data loss prevention (DLP).
