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 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.
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.
