Office 365 Data Loss Prevention

Microsoft Purview Data Loss Prevention (DLP) helps organizations identify, monitor, and protect sensitive information across Microsoft 365 cloud services. DLP uses built-in sensitive information types and policies to detect data such as financial, personal, or health records in locations including Exchange Online, SharePoint, OneDrive for Business, and Microsoft Teams. Administrators can configure policy tips, user notifications, and automatic protective actions—like blocking sharing or restricting access—to reduce accidental data leaks while maintaining productivity. Centralized policy management, detailed activity reports, and incident alerts support compliance with standards and regulations. Integrate with Microsoft Purview compliance portal for unified governance and extend protections to endpoints and on-premises repositories via supported connectors.
