Replace VDI with Zero Trust Browser: Even Thick-Client Apps Can Now Be Streamed
Zscaler, Wednesday, November 4th, 2026
Zscaler Zero Trust Browser adds Application Isolation to stream thick-client apps like SAP GUI and IDEs as a VDI alternative.
Zscaler announced that its Zero Trust Browser now supports thick-client application delivery through a capability called Application Isolation.
Applications such as SAP GUI, financial modeling tools, developer IDEs and database utilities run in isolated, ephemeral cloud environments managed by Zscaler and are rendered in the browser.
Zscaler positions it as an alternative to VDI, which it says costs up to $1,800 per user annually and exposes networks to lateral movement, especially for BYOD users and contractors who cannot install an endpoint agent.
Administrators assign applications through access policies and apply the same browser-native DLP used for web sessions.
