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.
Symantec DLP
- +Very mature detection across endpoint, network, storage and cloud channels.
- +On-premises deployment with a long track record in finance and government.
- +Extensive prebuilt policy templates for major regulatory frameworks.
- −Broadcom's acquisition changed licensing and support terms significantly for many customers.
- −Interface and workflow feel dated relative to newer entrants.
Best for Enterprises already invested in the Symantec estate.
Watch out Get licensing terms in writing. Post-acquisition renewal pricing has surprised many buyers.
