New Sophos Central Enhancements

  • New Partner Dashboard enabling Sophos partners to do group policy management across their customer base – make a change once and have it automatically replicate across multiple firewalls
  • New Group Policy Import enables one firewall to define the group policy during group setup making it easy to migrate from legacy CFM or SFM platforms
  • Scheduled Firmware Updates enables MR4 to be the first firmware you schedule using this new option
  • Full HA Support enabling easier management and improved fail-over support


New Group Policy Import makes switching to Sophos Central from CFM or SFM quick and easy.

With legacy SFM and CFM platforms coming to end of life soon, Sophos Central provides the ultimate platform for managing all your firewalls moving forward.  If you haven’t already, now is the time to switch.

Upgrade as soon as possible

While we always encourage you to keep your firewalls up to date with the latest firmware, over the next few months we are recommending you rapidly apply maintenance releases to ensure you have all the important security, performance, and feature enhancements applied as soon as possible.

Also ensure you have automatic pattern updates enabled so that you can be assured you have the latest protection updates.

XG Firewall v18 MR4 is an easy and fully supported upgrade from XG Firewall v17.5 MR6+ (including the latest v17.5 MR15 release). Please refer to the upgrade matrix for more details.

How to get it

As usual, this firmware update is no charge for all licensed XG Firewall customers. The firmware will be rolled out automatically to all systems over the coming weeks, but you can access the firmware anytime to do a manual update through the Licensing Portal.  Please refer to the documentation for more information on how to apply firmware updates.
