Cost considerations
Zscaler CASB relies on vendor quotes, so organizations cannot view price lists or tiers in advance. User reviews frequently label the product as expensive versus peers and point out that extra licences are needed for items like NSS or advanced DLP. Those add-on fees and per-user charges make total cost harder to predict as usage grows

Functionality
Zscaler CASB monitors SaaS and major IaaS clouds like AWS and Azure, enforces granular policies, and triggers real-time alerts with automated fixes. Unified dashboards reveal who is using which apps and how sensitive data moves, giving teams clear visibility across environments. Limited native protection for niche PaaS services keeps overall functionality a notch below platforms offering full multi-cloud breadth.

Compatibility
Zscaler CASB links natively to AWS, Azure and Google Cloud through API connections, so teams gain visibility with limited setup. The same controls cover on-prem and cloud resources, supporting hybrid and multi-cloud use. APIs are available for custom extensions, but deeper SDK toolkits found in a few competitors are absent.

User experience
Reviews state Zscaler CASB offers a clean dashboard and smooth end-user access, but administrators face a steep learning curve and awkward navigation. Users report that policy configuration and finding specific settings take extra effort, showing the interface is usable yet not truly intuitive. Documentation exists, yet frequent reliance on support points to a middling overall experience compared with other cloud security products

Customer support
Zscaler publishes clear guides and offers multiple support tiers, but standard coverage is 8×5 and 24/7 help requires an upgraded plan. User reviews point to slow or inconsistent response times and limited issue insight from the support team, indicating performance below top-tier expectations. These factors place Zscaler CASB customer support at a solid but unexceptional level compared with other cloud security products.
