Announcing the Illumio Endpoint for macOS!

Illumio Core Cloud customers can now install the VEN for the Illumio Endpoint on the latest versions of macOS; specifically, macOS versions 10.15 (Catalina), 10.16 (Big Sur), and 12.x (Monterey).

About a third of all endpoint platforms within an enterprise are running macOS. Not protecting this platform leaves organizations vulnerable to ransomware and malware. To prevent breaches and lateral movement in your organization, install the Illumio Endpoint on macOS and create full enforcement policies for your Mac endpoints.

For the steps to install the Illumio Endpoint on macOS, see Endpoint on macOS. For information about creating full enforcement policies, see Ruleset and Labeling Guidelines for Endpoints.
