StratoKey Cloud Access Security Broker (CASB)
Mid-market and enterprise teams protecting regulated data in SaaS applications should consider StratoKey Cloud Access Security Broker for its gateway-based encryption that tokenizes data before it reaches Salesforce, ServiceNow, and similar platforms, preventing exposure at the application layer itself. The tool holds FIPS 140-3 validated libraries and enforces group policy-based decryption control, which directly addresses PR.AA and PR.DS under NIST CSF 2.0. Skip this if you need visibility into threats after compromise or incident response automation; StratoKey prioritizes prevention and access control, not detection or recovery workflows.
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.
