Microsoft Purview DLP Limitations and How to Close Them
Security teams that roll out Microsoft Purview DLP inside their Microsoft ecosystem often assume coverage extends further than it does. Policies apply cleanly to Word, Excel, and Outlook. Then a sensitive.dwg is inspected only by extension because Purview doesn't scan CAD content, a developer on a Linux workstation falls outside endpoint coverage entirely, or raw source code moves to a USB drive without matching the source-code classifier, which runs on the endpoint only for Office and PDF files.
