What the comparison says

Both platforms are SaaS only, so deployment model is not what separates them here. Microsoft Purview DLP is described as medium to reach value, against medium for Zscaler DLP.

Microsoft Purview DLP licenses on M365 E5 Compliance tier, Zscaler DLP on per user, per tier. Neither bills on data volume, so the comparison is about what each licence includes rather than how much you send it.

Microsoft Purview DLP leads on pricing value, and Zscaler DLP does not lead by a clear margin anywhere in this set.

Microsoft Purview DLP

  • +Effectively included for organisations already licensed for M365 E5 Compliance.
  • +Native coverage of Exchange, SharePoint, OneDrive and Teams with no connectors to build.
  • +Policies follow the label, so classification and protection stay attached to the file.
  • −Coverage outside the Microsoft estate is thin. Third-party SaaS and non-Windows endpoints lag.
  • −No on-premises option; inspection happens in Microsoft's cloud.

Best for Microsoft-centric organisations whose sensitive data lives in M365.

Watch out If material data sits outside Microsoft, this leaves real gaps.

Zscaler DLP

  • +Inline enforcement at internet scale with minimal latency impact.
  • +Natural fit where Zscaler already handles web and private access.
  • +Exact data match and indexed document matching are available at higher tiers.
  • −SaaS only, with inspection performed in Zscaler's cloud.
  • −Value depends heavily on already routing traffic through the Zscaler platform.

Best for Enterprises already standardised on Zscaler for secure access.

Watch out Standalone value is limited. This is a platform module rather than a product.
