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 security teams managing acceptable use policy enforcement will get the most from MailGuard ImageGuard because it catches illicit imagery in email before it hits archives or creates liability exposure. The tool scans all image files in real time across on-premises mail servers and logs sender/receiver metadata for compliance audits, directly supporting policy enforcement workflows that most DLP vendors treat as an afterthought. Skip this if you need cloud-native SaaS deployment or detection capabilities that extend beyond image classification; ImageGuard is purpose-built for organizations with on-premises infrastructure and a specific mandate around visual content governance.
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.
