CASB - Cloud Access Security Broker vs Cloud Monitor (for Microsoft 365): 2026 Comparison

CASB - Cloud Access Security Broker

Mid-market and enterprise teams struggling with shadow IT and SaaS sprawl will get the most from Olfeo's CASB, which pairs real-time application discovery with behavioral anomaly detection to catch unauthorized access patterns that static policy alone misses. The platform covers six NIST CSF 2.0 functions across monitoring and access control, with particular strength in DE.CM continuous monitoring and DE.AE incident characterization. Skip this if you need deep integration with on-premises identity systems or legacy application controls; Olfeo is built for cloud-first environments where your data is already scattered across multiple SaaS platforms.

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.
