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
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
