Release notes:

What’s New in XG Firewall v17.5

Here’s a quick overview of the key new features in v17.5. For a more detailed description please refer to Sophos-XG-firewall-v17.5-whats-new.pdf

Lateral Movement Protection

extends our Security Heartbeat automated threat isolation to prevent any threat from moving laterally or spreading across the network, even on the same subnet. The firewall instructs all healthy endpoints to completely isolate any unhealthy endpoints.

Synchronized User ID

utilizes Security Heartbeat™ to greatly streamline authentication for user-based policy enforcement and reporting in any Active Domain network by eliminating the need for any kind of server or client agent.

Education Features

such as per-user policy-based control over SafeSearch and YouTube restrictions, teacher enabled block-page overrides, and Chromebook authentication support

Email Features

adds Sender Policy Framework (SPF) anti-spoofing protection and a new MTA based on Exim which closes a couple of top requested feature differences with SG Firewall.

IPS Protection

is enhanced with greatly expanded categories enabling you to better optimize your performance and protection.

Management Enhancements

including enhanced firewall rule grouping with automatic group assignment, a custom column selection for the log viewer; And revamped online help with learning content approach

VPN and SD-WAN Failover and Failback

including new IPSec failover and failback controls and SD-WAN link failback options.

Client Authentication

gets a major update with a variety of new enhancements such as per-machine deployment, a logout option, support for wake from sleep, and MAC address sharing.

Sophos Connect

is our new IPSec VPN Client that’s free for all XG Firewall customers that makes remote VPN easy for users and supports Synchronized Security.


In addition, coming in a following Maintenance Release we have:

Wireless APX Access Point Support

provides support for the new Wave 2 access points providing faster connectivity and added scalability.

Airgap Support

for deployments where XG Firewall can’t get updates automatically via an internet connection (due to an “airgap” or physical isolation) – XG Firewall can now be updated via USB.

Sophos Central Management of XG Firewall

With v17.5, XG Firewall is also joining Sophos Central.  The Early Access Program for Sophos Central Management of XG Firewall is expected to start soon.

You will be able to manage XG Firewall from within Sophos Central along with all your other Sophos Central products.  And there’s a few great new features coming along with Sophos Central Management of XG Firewall:

  • Secure access and management with single-sign-on through Sophos Central from anywhere
  • Backup management and storage for your regularly scheduled firewall backups
  • Firmware update management to make multiple firewall updates easy
  • Light-touch deployment to enable easy remote setup of a new Firewall

A feature is not working as expected? You have found a bug?

Please post it in this forum with a detailed description and – if possible – with some details how our team can reproduce the behaviour. To increase readability we would like to ask you to use one post per issue.

Our engineering teams check the forum on a regular base.
