What is the difference between an SG and XG firewall?
When you buy a Sophos Firewall, sooner or later you will wonder what the difference is between an SG and an XG firewall.
With the SG or XG firewall, the difference lies solely in the pre-installed operating system. While the SG comes with the UTM operating system, the XG firewall is equipped with the new Sophos Firewall OS (SFOS).
Performance and design
Visually, the differences between the two hardware variants are moderate. Only the small desktop series, with the XG 86/106/115/125/135 models, have a more rounded design. The SG series in this segment comes in the usual square format. However, in both series the same technical components were used.
Note: If you are looking for a new firewall, we would strongly advise you to have an XG firewall. The future of Sophos clearly lies in the Sophos Firewall OS and Synchronized Security.
