Application Resilience policies for Zscaler Client Connector

Zscaler™ Client Connector (Client Connector), formerly Zscaler App (Z App), enforces security and policy control for millions of devices worldwide.

You can activate an Application Resilience policy to collect information about the functional status of Client Connector installed on your Windows devices and to view the results in reports. You can also configure the policy to attempt to repair or reinstall Client Connector.

Application Resilience policies for Client Connector are supported only on devices running a supported version of the Windows operating system and one of the following versions of Client Connector:

  • 3.x or higher

    NOTE  Significant software changes in higher versions may cause health checks to become invalid.

If you select Report higher versions as Compliant, higher versions report Compliant without running health checks.

In addition to checking the version, the following table describes the health checks performed:
