Organizations have sensitive information under their control such as financial data, proprietary data, credit card numbers, health records, or social security numbers. To help protect this sensitive data and reduce risk, they need a way to prevent their users from inappropriately sharing it with people who shouldn’t have it. This practice is called data loss prevention (DLP).
In Microsoft 365, you implement data loss prevention by defining and applying DLP policies. With a DLP policy, you can identify, monitor, and automatically protect sensitive items across:
- Microsoft 365 services such as Teams, Exchange, SharePoint, and OneDrive
- Office applications such as Word, Excel, and PowerPoint
- Windows 10, Windows 11 and macOS (Catalina 10.15 and higher) endpoints
- non-Microsoft cloud apps
- on-premises file shares and on-premises SharePoint.
