Based 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.
Security and compliance teams managing Outlook environments need accidental send prevention that actually works, and SendGuard for Outlook delivers it through pre-send recipient confirmation and reply-all blocking rather than post-incident recovery. The tool logs compliance events for GDPR, HIPAA, GLBA, CCPA, and PIPEDA, covering the regulatory posture most mid-market and enterprise organizations require. Skip this if you need DLP that catches policy violations before send; SendGuard focuses on human error and user awareness (NIST PR.AT) rather than content inspection, so buyers looking for data classification and sensitive data detection should evaluate purpose-built DLP solutions first.
