Cloud Monitor (for Microsoft 365)
K-12 IT teams protecting student data in Microsoft 365 environments should choose Cloud Monitor because it combines continuous M365 activity monitoring with automated detection of risky SaaS permissions, closing the gap between what happens inside Exchange and OneDrive and what happens when staff accidentally grant third-party apps access to student records. The platform covers DE.CM and DE.AE functions across login anomalies, file sharing patterns, and download behavior with 24/7 oversight, which matters when you're liable for FERPA compliance. Skip this if your district runs a hybrid environment heavy on Google Workspace or needs deep endpoint detection; Cloud Monitor is M365-specific by design.
Zscaler Cloud Access Security Broker (CASB)
Mid-market and enterprise security teams drowning in SaaS sprawl need Zscaler Cloud Access Security Broker for its inline proxy architecture that catches threats in motion without forcing users through a VPN bottleneck. The platform covers both real-time API inspection and data at rest scanning across Microsoft 365, Salesforce, and AWS, hitting NIST PR.DS and DE.CM functions hard. Skip this if your organization runs primarily on-premises applications or lacks the cloud adoption density to justify a dedicated CASB; you'll overpay for capabilities you don't need.
