Update SFOS firmware on Sophos Firewall

In this tutorial we will show you how to update the firmware of your XG Firewall to the latest version.

Info: In this guide, we assume that you are using a Sophos firewall with the SFOS and that it is associated with a valid Sophos ID. Before you follow this guide and install an update to your firewall, be sure to create a backup beforehand. You should never assume that everything will always work properly after an update.

Download SFOS firmware manually

Before you can install the new firmware on the firewall, you must first download it from the Sophos Licensing Portal.

Note: If you have Sophos Premium Support (included with every bundle), you can also download the latest firmware automatically from the GUI of your Sophos Firewall. To do this, jump to the following section: Install SFOS firmware automatically.

  1. Contact us at https://id.sophos.com with your Sophos ID an.
  2. Select under the menu item My applications in the list the item MySophos off.
  3. Click Network Protection.
  4. Click Show devices.
  5. Choose your device from the list, which you want to update to the latest version and then click on Download.
  6. The latest firmware versions are displayed in a pop-up window. Select the one that suits you best and click on Download.
  7. Finally, accept the EULA (End User License Agreement) and the file will be downloaded.

The above steps are explained here again step by step with screenshots:

Install SFOS firmware manually

The downloaded firmware can now be installed on the Sophos Firewall.

  1. Log in to your XG Firewall.
  2. Click in the navigation on Backup & Firmware.
  3. Under the heading Firmware you will find a list of available versions. Click on the upload icon.
  4. The "Firmware Upgrade/Downgrade" pop-up window will appear. Select the firmware from your computer and click Upload firmware or Upload & Boot.

The above steps are explained here again step by step with screenshots:

Note: Think carefully about which option you choose. At Upload firmware only transfers the file from your computer to the firewall, while with Upload & Boot the firewall is also started with the latest firmware afterwards.

Info: If you have set up an HA cluster, we always recommend the variant Upload & Boot to select. This will update the two firewalls one after the other and there will be no interruption in the network.

Should you choose Upload firmware you can choose the time of the update yourself. Click under the heading Firmware on the icon with the two arrows as soon as the time is right for the installation.

If you have a valid Sophos Enhanced Support license, you can save yourself all the effort of the above steps. Enhanced Support provides you with one-click automatic updates directly in the GUI of your firewall.

Note: If you can't wait for a new firmware version to be automatically displayed on your firewall, you can always update manually.

  1. Log in to your XG Firewall.
  2. Click in the navigation on Backup & Firmware.
  3. Click under the heading Latest Available Firmware with the listed update to Download.
  4. Once the download is complete, you can start the installation by clicking on Install launch.
