What's New in Zscaler Client Connector

4.5.1

June 1, 2026

* Fixes an issue on iOS 26 where Zscaler Client Connector remained stuck in an authentication loop while authenticating through an SSO extension for several minutes before completing sign-in. * Fixes an issue where devices connected to IPv6-only networks and in tenants without the IPv6 feature enabled for Zscaler Client Connector fell back to Zscaler Tunnel (Z-Tunnel) 1.0, because the QUIC drop policy wasn't applied. * Fixes an issue where after a device reboot on a cellular-only network, traffic intermittently failed to route through the Zscaler Internet Access (ZIA) tunnel. * Fixes an issue where Zscaler Client Connector displayed the message Invalid MDM Config, when Zscaler Digital Experience (ZDX) remained stuck in a connecting state due to an incorrect management device management (MDM) configuration.

Erratic

It need a big update, it can’t drain the battery this fast plus how it fails to connect multiple times, with my 17 pro max is a nightmare, with my 12 pro max works better.

My IPhone started behaving erratically after installing this app. IPhone’s battery is draining very fast and restarting frequently. It needs an update.

How does the app ensure security?

The app creates a lightweight HTTP tunnel that connects your device to Zscaler's cloud security platform. This platform filters web traffic and protects against threats, even from mobile apps, providing consistent security without requiring PAC files or authentication cookies.

Is this app free to use?

The Zscaler Client Connector app itself is free to download. However, it requires an active enterprise subscription to Zscaler's Mobile Security service. You will need to follow instructions from your IT organization to use the app.

What devices is this app compatible with?

This application is designed for iOS devices. It is intended for use with an active enterprise subscription to Zscaler's Mobile Security service, and usage is managed by your organization's IT department.
