Adaptive Delivery

Ivanti Secure Access Client (both Windows/macOS desktop clients, Host Checker, and Windows Terminal Services) feature “Adaptive Delivery”, which is a mechanism for installing and launching Ivanti Secure Access Client from a web browser. The exact mechanism used for Adaptive Delivery depends on many factors, including:

1.The Ivanti Secure Access Client launched/installed

2.The client operating system type and version

3.The web browser type and version

4.The security settings of the client operating system and browser

To leverage Adaptive Delivery for a client/OS/browser combination, you may need to enable the appropriate technology on the endpoint device.

PSAL leverages “URL handler” functionality by invoking a custom URL in a manner that instructs the web browser to execute a program that launches/installs the appropriate Ivanti Secure Access Client. PSAL was created to address both the restrictions placed on Java on macOS and the depreciation of Java (and ActiveX) plug-ins in Google Chrome and the Microsoft Edge browser. You can read more about the PSAL in article KB40102.

The following table shows the Adaptive Delivery mechanism for client/OS/browser combinations.

Operating System	Ivanti Secure Access Client	Web Browser	Adaptive Delivery Mechanism
Windows	All	Firefox Google Chrome Edge Browser	Pulse Secure Application Launcher
macOS	Ivanti Secure Access Client Host Checker (HC)	Safari	Pulse Secure Application Launcher
macOS	JSAM	Safari	Pulse Secure Application Launcher

•Chrome is compatible rather than fully qualified on Windows.

•Chrome and Firefox on macOS are not supported (only Safari is supported on macOS), but PSAL will be invoked if an attempt is made to use either Chrome or Firefox on macOS for the Ivanti Secure Access Client or Host Checker
