Next-generation firewall delivering 47,000 Mbps firewall throughput and 2470 Mbps of Xstream TLS inspection. Built for a large site or campus.

What are the Sophos XGS 3100 specifications?+

The XGS 3100 delivers 47,000 Mbps firewall throughput, 10,500 Mbps IPS, 7400 Mbps threat protection and 2470 Mbps of Xstream TLS inspection, supporting 12,260,000 concurrent connections.

How many users does the XGS 3100 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Sophos does not publish user counts per model, so we do not quote them.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 2470 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?+

Rackmount XGS models have one Flexi Port bay that takes an expansion module, including 10 Gigabit fibre, PoE and high-density copper.
