• Manage the sites in which you can group your devices by customer, location, department, etc.
• Add (by deploying agents) and manage all your devices, including Windows, Mac and Linux devices, mobile devices and network devices and printers.
• Create and manage components (applications, monitors and scripts) that get deployed to your endpoints.
• Schedule jobs.
