Sophos XDR: How to query check all Windows workstations and servers need to reboot

Overview

Sophos Extended Detection and Response (XDR) lets you investigate detected threats (“threat cases”) and search for new threats or security weaknesses. It also lets you monitor devices and fix issues remotely. Sophos XDR gives you access to both data stored in the cloud and directly on the device. Which means you always have the most up-to-date data possible.

The article guides us to use the Live Discover tool of Sophos CIXA with EDR to be able to query all Windows workstations and servers need to reboot. That helps to reduce the time for administrators having to go down to each machine to check
