Client App Management

Citrix Workspace app 2305 for Mac now offers Client App Management capability that makes the Citrix Workspace app a single client app required on the end point to install and manage agents such as End Point Analysis (EPA) plug-in.

With this capability, administrators can easily deploy and manage required agents from a single management console.

Note:

• This feature is applicable to Workspace (cloud) sessions only.
• Global App Configuration service is a prerequisite for this feature.

Client App Management includes the following steps:

• Administrators must specify the agents required on end users’ devices in the Global App Configuration service. With this technical preview, administrators can specify an Endpoint Analysis (EPA) agent.
• Citrix Workspace app fetches the list of agents from Global App Configuration service.
• Based on the list fetched from Global App Configuration service, Citrix Workspace app downloads the agent packages through the auto-update service. If the agent isn’t previously installed on the end point, Citrix Workspace app triggers the installation of the agent. If the agent is already installed, Citrix Workspace app triggers an update to the agent (if the version of the downloaded agent is higher than the installed version.)

Citrix Workspace app ensures to automatically update the agents whenever an update is available in the future.

The following diagram illustrates the workflow:
