We’ve created a comprehensive library of “How To” videos, including a series of Getting Started and Networking videos, to help you get the most out of your XG Firewall.

Sophos XG Firewall takes an innovative approach across all areas of network security. From the way firewalls are managed, to the way they report information and how they work with other security systems around them, giving you an unprecedented level of simplicity, insight, and advanced threat protection. In this video we cover how to setup a new XG Firewall out of the box.There are five key sections to this video:1. Creating a Sophos ID (0:30)2.

Today, I’d like to share a short Getting Started video that walks you through how to keep your XG Firewall firmware up to date, as well as how to roll back to a previous firmware version if necessary.

In this video, we’ll show you how to:

  • Find out when a new firmware update is available
  • Navigate to the firmware update screen
  • Download and install the firmware update
  • Verify the new firmware is applied after reboot
  • Download and install the firmware update manually from MySophos
  • Restore a previous firmware version

You can watch the entire Getting Started video series on the Sophos Products YouTube channel. And you can check out all the posts in this XG Firewall “How To” series on the Sophos Blog.

With the launch of XG Firewall v18 growing ever nearer, many of your customers will be planning for their software upgrade ahead of time, or maybe even considering a migration to XG from another firewall platform.

We will detail here which hardware models can upgrade to XG v18 and where a hardware refresh would be necessary to support an upgrade.

The good news is that all current and previous XG and SG Series hardware models with at least 4 GB of RAM can upgrade – a valid license is also necessary, of course. The XG 86 and 106 models were previously introduced specifically to address this requirement.

Restrictions for Previous Revisions

Any model with less than 4 GB cannot upgrade to v18.

XG v18 and Beyond Hardware Support Policy

This graphic provides an overview of the planned support policy.

  • Any model which is not supported in v18 will continue to be supported on v17.5
  • Any model which is only supported up to v18, e.g. older XG/SG revisions, can remain on v18 and will continue to receive support in line with our overall support policy

A complete overview of all models can be found at the bottom of this post.

Note: *Models with less than 4 GB are not supported in v18.

Determining the Revision Number of an Appliance

Customers may not know which revision they’re currently on.

  • The revision number appears on the silver label which can usually be found on the underside of the appliance (near the manufacture date) but that may not be accessible if the hardware is mounted in a rack.
  • You can also determine the revision number from the serial number. This is explained in this Knowledge Base article:
