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 drowning in misdirected email incidents will see immediate value in Egress Prevent's relationship mapping engine, which flags messages sent to wrong recipients before they land in inboxes. The tool's real-time point-of-send detection and Bayesian inference for continuous risk assessment directly address PR.DS (data security) and DE.CM (continuous monitoring) under NIST CSF 2.0, meaning you're stopping exfiltration at the moment of highest visibility. Skip this if your organization needs broader insider threat capabilities beyond email; Egress Prevent owns the send-time problem but doesn't replace behavioral analytics for lateral movement or cloud data access abuse.
Mid-market and enterprise teams managing sensitive email attachments in Exchange environments will get real value from AttachView's permission granularity; you can restrict open, save, copy, and print at the user, group, IP, and device level without forcing users into a separate portal. The on-premises CAS installation handles over 400 file formats without requiring local applications, reducing both support burden and data exfiltration surface. Skip this if you need cloud-first deployment or DLP that covers email body content and metadata alongside attachments; AttachView is purely attachment-focused.
