You can customize the messages for Zscaler Client Connector-based notifications that are displayed for end users when a Cloud App Control policy configured in Internet & SaaS is triggered by the end user's activity. For example, you can block your organization users from interacting with and uploading files to AI and ML applications such as ChatGPT and Google Gemini and display a notification informing the user regarding the policy violation.

Client Connector-based notification for end users is supported only for Block rules under specific conditions when the application access is allowed but specific interactions with the application are blocked (e.g., viewing a social networking site is allowed but posting content is blocked).

These end user notifications (EUNs) are triggered by Internet & SaaS based on your policy configuration and are issued by the Client Connector service that is installed on the users' endpoints. You can customize various elements of the notification, including the notification message for different policy actions, company name, logo, information displayed on the notification, duration of the notification, and more. You can modify the default notification message that is preconfigured in the Admin Portal and additionally create custom messages to allow the selection of different notification messages for individual Cloud App Control rules. This allows you to display customized notification messages for different types of audiences (e.g., partners and organization employees). To learn more, see About Zscaler Client Connector-Based End User Notifications.

To display the EUN for a specific Cloud App Control rule, you need to enable the EUN within the rule configuration page and select the notification message that must be used for that particular rule. To learn about Cloud App Control policy configuration, see Adding Rules to the Cloud App Control Policy.

In addition to the notification message, ensure that the notification customizations shared by all Client Connector-based EUNs are configured as needed. These customizations are available under the Settings option on the Client Connector EUN page.

You can edit both default and custom notification messages to customize them based on your requirements subject to the following conditions:

• The Channel field is non-editable in both default and custom messages
• The Name field is non-editable in default messages

The default notification additionally provides a Reset All option that allows you to restore the default message. This option appears only when you modify the default message.
