The setup is straightforward, but the satellite service installation file could be separated from the server one.

* The status overview page provides a state of computers monitored and provides quickly what users need to focus on * The satellite service installed on remote computers is an easy way to add clients, plus it's easy to deploy and to configure * The licence is perpetual and not linked to one computer, so it's possible to remove a licence from one computer and use it on another with no extra cost
