Reco AI Governance and Security vs Zscaler Cloud Access Security Broker (CASB): Side-by-Side Comparison (2026)

Reco AI Governance and Security

Mid-market and enterprise security teams drowning in Shadow AI sprawl need Reco AI Governance and Security because it actually finds and tags AI agents before they leak data, not just after. The platform covers seven NIST CSF 2.0 functions including continuous monitoring and data security, and its integrations with Microsoft 365, Google Workspace, and ChatGPT mean you're catching risk where employees actually work. Skip this if your organization isn't actively using generative AI tools yet; Reco solves a problem that doesn't exist without adoption at scale.

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.
