Proofpoint DLP
- +Strongest email channel coverage in this table, which is where most leaks actually occur
- +Insider threat management correlates user behaviour with data movement
- +Good balance of detection quality and operational simplicity
- −Primarily cloud-delivered — on-premises options are limited
- −Coverage of data at rest in on-premises storage is thinner than the incumbents
Best for Organisations whose primary data loss channel is email and user behaviour
Watch out If you need endpoint and storage DLP as well, this is only part of the picture
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
