When must I use the Endpoint Policy ManagerCloud Client installer versus the on-prem Endpoint Policy Manager CSE?
The Netwrix Endpoint Policy Manager (formerly PolicyPak) Cloud Client is the software you download to enable a machine to join your instance of Endpoint Policy Manager Cloud, claim a license, and download policies.
The Endpoint Policy Manager Cloud Client will also download the Endpoint Policy Manager Client Side Extension to process of the policies.
When you install the Endpoint Policy Manager cloud client, the CSE is downloaded from the cloud service automatically at the same time.
To keep the Endpoint Policy Manager Cloud Client up to date, as well as the Endpoint Policy Manager Client Side Extension, you need to be proactive.
