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.

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.
