CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams managing data across cloud apps, email, and endpoints will get the most from Zscaler Unified DLP because it actually inspects encrypted traffic at scale without crushing performance, something most DLP vendors stumble on. The lightweight agent plus TLS/SSL inspection handles the messy reality of modern work: SaaS sprawl, remote endpoints, and encrypted channels that traditional DLP can't see into. Skip this if your organization runs mostly on-premises applications or lacks the budget for cloud-native architecture; Zscaler assumes you've already committed to moving inspection off the perimeter.
Mid-market and enterprise security teams with mature email and cloud environments should prioritize Proofpoint Enterprise DLP for its behavioral AI that catches insider threats during exfiltration, not just at the gateway. The integration of insider threat management and continuous monitoring across email, cloud, and endpoints addresses both accidental leaks and malicious data movement, covering NIST DE.CM and PR.DS effectively. Skip this if your organization relies heavily on unmanaged SaaS apps outside Microsoft 365 or needs deep DSPM capabilities; Proofpoint's strength is enforcement, not discovery of shadow data.
