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 protecting sensitive data in Microsoft 365 should choose Egress Protect for its post-send message control, which lets you revoke access and restrict forwarding even after recipients open encrypted email. The tool covers three NIST CSF 2.0 functions (PR.DS, PR.AA, DE.CM), with particular strength in access enforcement through granular controls and continuous audit trails that satisfy compliance auditors. Skip this if you need unified DLP across cloud storage, web, and endpoints; Egress Protect is email-centric and won't replace a platform-wide data loss prevention strategy.
Mid-market and enterprise security teams drowning in email DLP tuning will see immediate value in Zivver Secure Email Gateway because it detects sensitive data without requiring users to classify it, reducing the false-positive fatigue that kills adoption. The tool handles GDPR, HIPAA, and DORA compliance out of the box while integrating directly into Microsoft 365 and Gmail without ripping out existing infrastructure. Skip this if your organization needs advanced threat detection on inbound mail or is heavily invested in on-premises Exchange; Zivver's strength is automated outbound protection, not inbound scanning.
