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 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.
Mid-market and enterprise teams with Microsoft 365 or Google Workspace will get the most from INKY Outbound Mail Protection because it actually catches insider data exfiltration before it leaves the network, not after breach forensics. The tool maps directly to NIST PR.DS Data Security controls with real-time sensitive data detection on outgoing email, and integrates natively with your existing cloud email stack without added infrastructure. Skip this if your primary concern is inbound phishing or if you need DLP that covers file shares and endpoints; INKY is deliberately email-egress focused.
