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.
