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
The visual differences between the two hardware variants are limited. Only since revision 3 of the 105/115/125/135 series the small desktop series comes with a completely different design for the first time. In terms of hardware, however, the same components were used in both models.
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.
