Endpoint data loss prevention (endpoint DLP) extends the activity monitoring and protection capabilities of Microsoft Purview data loss prevention (DLP) to sensitive items that are on Windows 10/11 devices. Once devices are onboarded into the Microsoft Purview solutions, the information about what users are doing with sensitive items is made visible in activity explorer and you can enforce protective actions on those items via DLP policies.

Once the Firefox extension is installed on a Windows 10/11 device, organizations can monitor when a user attempts to access or upload a sensitive item to a cloud service using Mozilla Firefox and enforce protective actions via DLP.
