Zscaler’s Device Posture framework in Client Connector supports a broad set of posture checks on both Windows and macOS, such as Certificate Trust, Client Certificate, Firewall status, Full Disk Encryption, Domain Joined, and multiple EDR detections. These are listed in Zscaler technical training material as common capabilities for “Windows und macOS.”
However, Zscaler’s advanced integration with CrowdStrike introduces additional posture signals based on Zero Trust Assessment (ZTA). In the same material, CrowdStrike ZTA Score is explicitly annotated with a Windows-specific minimum version (“CrowdStrike ZTA Score (Win v.3.4.0+)”), highlighting that this ZTA-based posture is implemented for Windows only in the current releases, while the shared list for macOS does not include its own ZTA-specific version.
The newer ZTE/EDU-202 engineer materials build on this by describing separate ZTA Device OS and Sensor scores, and the exam maps this Windows-only ZTA enforcement to the CrowdStrike ZTA Sensor Setting Score option. In contrast, Client Certificate, Full Disk Encryption, and Domain Joined are documented as cross-platform posture types, not restricted to Windows.
