Within the Zscaler Client Connector administration portal, an App Profile defines how the client behaves for a set of users or devices. A key element of any App Profile is the associated Forwarding Profile. The Forwarding Profile tells the Zscaler Client Connector how to handle traffic in different network conditions: for example, whether to send traffic through Z-Tunnel 2.0 to ZIA and/or ZPA, rely on a PAC file, or bypass Zscaler when on trusted networks.

When you create or edit an App Profile, selecting a Forwarding Profile is mandatory because it determines how user traffic will actually reach the Zscaler cloud. Without a Forwarding Profile, the App Profile would not know which forwarding mode to use, and the client would have no consistent instructions on when and how to tunnel or bypass traffic. In practice, customers often define multiple Forwarding Profiles (for example, “ZIA-only,” “ZPA-only,” or “ZIA and ZPA”) and then bind them to different App Profiles for different user groups or device types.

“Bypass,” “authentication,” or “exception” profiles are not separate required profile objects in the ZCC policy model. Any bypass or exception behavior is defined inside the forwarding and app profile logic, not as standalone mandatory profiles. Therefore, a Forwarding Profile is the one element that every ZCC App Profile must include.
