Microsoft Purview DLP

Microsoft Purview DLP is the obvious choice for Microsoft 365 enterprises. Zero additional licensing cost for E3 and E5 customers, a single policy engine covering Teams, SharePoint, OneDrive, Exchange, and Windows endpoints, and the broadest compliance certification set in the DLP category make it the lowest-friction entry point into enterprise DLP available.

The limitation is equally obvious. Microsoft Purview DLP protects Microsoft data flows. Non-Microsoft channels including Slack, Google Workspace, non-Windows endpoints, and custom applications require third-party connectors that are less capable than native coverage. False positive rates without significant tuning are also consistently flagged by reviewers.

The verdict: Microsoft Purview DLP is right for Microsoft 365 enterprises wanting DLP bundled into existing licensing without deploying a separate vendor. Organisations with significant non-Microsoft data flows should evaluate Forcepoint or Netskope.
