Sophos XGS 128 and 128w firewall

Next-generation firewall delivering 19,100 Mbps firewall throughput and 1,450 Mbps of Xstream TLS inspection. Built for a busy small office. The w models add a built-in Wi-Fi radio.

In plain terms: Size on the TLS inspection figure, not firewall throughput. Almost all web traffic is encrypted, so 1,450 Mbps is what actually limits inspection on this model.

What are the Sophos XGS 128 specifications?+

The XGS 128 delivers 19,100 Mbps firewall throughput, 4,650 Mbps IPS, 4,000 Mbps threat protection and 1,450 Mbps of Xstream TLS inspection, supporting 6,000,000 concurrent connections.

How many users does the XGS 128 support?+

Sophos does not publish user counts per model, so we do not quote them. Sizing depends on your internet speed, how many services you enable and how much traffic you inspect. Send us those three and we will size it against the Sophos sizing tool.

Should I size on firewall throughput or TLS inspection?+

Size on TLS inspection. Almost all web traffic is encrypted, so the 1,450 Mbps TLS figure is what limits real-world inspection. The firewall throughput figure assumes unencrypted traffic you will rarely see.

Standard or Xstream Protection?+

Xstream adds TLS 1.3 inspection, cloud sandboxing and the advanced IPS. For any site whose users browse the web, Xstream is the bundle that inspects encrypted traffic. Standard covers the base firewall plus SD-WAN and ZTNA.

Can this model be expanded later?+

Desktop XGS models cannot be expanded. If you expect to need more ports or 10 Gigabit uplinks, size up now rather than later.
