Digital Guardian
- +Tracks data lineage at the endpoint, so it can follow a file through copies and renames
- +Available as on-premises, hosted or managed service
- +Particularly strong for intellectual property protection rather than only regulated data
- −Agent footprint and tuning effort are heavier than most alternatives here
- −Pricing sits at the enterprise end, and the managed option adds materially to it
Best for Manufacturers and research organisations protecting intellectual property
Watch out Pilot the agent on real workloads before rollout — performance is the usual complaint
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
