What the comparison says

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

Proofpoint DLP licenses on per user, 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.

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

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.
