Sophos XDR: Instructions for query to check opened network ports on workstations and servers

Overview

Sophos Extended Detection and Response (XDR) allows you to investigate detected threats (“threat cases”) and search for new threats or security vulnerabilities. It also enables remote monitoring and troubleshooting of devices. With Sophos XDR, you can access both cloud-stored data and data directly on devices, ensuring you always have the most up-to-date information.

This article provides a guide on how to use the Live Discover tool of Sophos CIXA with EDR to query the entire workstation and server system to obtain information about which machines have been installed with Sophos certificates. This helps reduce the time for administrators to manually check each machine for verification.
