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
