A brand-new range of hardware appliances delivering powerful protection and performance for Sophos Firewall

Today we’re announcing a brand-new range of hardware appliances for Sophos Firewall OS, the XGS Series. This is not just a technology refresh; our firewall appliances have been completely reengineered and now come with a dual processor architecture to deliver a significant performance increase over previous models.

The new XGS Series appliances release with Sophos Firewall OS v18.5, have a new simplified licensing scheme, and as if that wasn’t enough, we’re also changing the overall product name from Sophos XG Firewall to Sophos Firewall.


Dual Processor Architecture

Every XGS Series appliance combines a multi-core x86 CPU with a dedicated Xstream Flow Processor for application acceleration. Xstream Flow Processors are Network Processing Units (NPUs) which now add a hardware layer FastPath to extend the Xstream architecture that we introduced in SFOS version 18.

Flexible to the core

One benefit of the hardware platform that we’ve chosen, is that our Xstream Flow Processors are programmable. This allows us to extend the offload capabilities in future software releases, providing additional performance improvements, even for things like crypto processes. This, combined with the ability to modify and extend connectivity on every appliance, delivers a truly future-proof solution which can adapt as the network, workforce and security infrastructure evolves.

Protection and Performance

The increase in performance varies by model and test but you’re likely to see at least a 2X performance increase over v18 running on XG Series hardware and numbers to meet or beat our key competitors on the all-important Price per Protected Mbps. The additional performance headroom allows customers to turn on essential protection, such as TLS Inspection, with the confidence that they’re removing a huge blind spot in their network visibility – which hackers are increasingly exploiting – whilst maintaining their network performance.

Sophos Firewall OS v18.5

The new appliances come with the latest v18.5 software release which not only provides support for the new hardware, but also includes all the 18.x maintenance releases since the v18 release with extensive security hardening features, VPN and SD-WAN enhancements, Central Management and Reporting capabilities, and many more improvements.

Note: 18.5 for all non-XGS Series customers is currently expected to be available in the June/July timeframe.

Product naming and availability

The XGS Series model line-up is similar to what we offer with the XG Series:

  • Desktop model numbers have been increased by ‘1’
  • 1U and 2U rackmount model numbers have an added ‘0’

We’re launching all models over a period of about four to six weeks. All XGS Desktop and 1U 2xxx and 3xxx models are available from today, April 21st and the XGS 1U 4xxx and 2U models will be available from late May.

As actual availability can vary by model and region, please reach out to your local Sophos or distribution team for further details.

The XG Series models remain available for purchase.
