Model XGS 3100

Option 3-Year Xstream Protection

  • Enterprise-grade firewall throughput up to 47 Gbps for high-speed network protection
  • TLS 1.3 inspection at 2.47 Gbps secures encrypted traffic visibility
  • Dual-processor architecture with Xstream Flow Processor offloads trusted traffic for performance
  • 1U short-depth rackmount with 8 copper and 4 fiber ports fits dense deployments
  • Includes 3-year Xstream Protection subscription for zero-day threat defence

Product Identity

The Sophos XGS 3100 is a 1U rackmount network security appliance designed for mid-sized and distributed organizations. It combines a dual-processor architecture with an AMD x86 CPU and a Marvell NPU to deliver high-throughput firewall and inspection capabilities. The unit ships with a three-year Xstream Protection subscription and includes a rackmount kit.

Fit and Limits

This appliance suits teams that need integrated SD-WAN orchestration, TLS 1.3 inspection, and zero-day threat protection in a single chassis. Buyers who require built-in RAID storage redundancy, internal expansion cards, or wireless connectivity should look at other form factors because this model offers none of those features.

Deciding Specification

The appliance provides eight Gigabit copper ports, two SFP Gigabit fiber ports, and two SFP+ 10 Gigabit fiber ports for flexible WAN and LAN connectivity. All network interfaces are fixed on the base unit, so the port count and speed mix is the single specification that determines whether this model matches the deployment topology.

Highlights

  • Enterprise-grade firewall throughput up to 47 Gbps for high-speed network protection
  • TLS 1.3 inspection at 2.47 Gbps secures encrypted traffic visibility
  • Dual-processor architecture with Xstream Flow Processor offloads trusted traffic for performance
  • 1U short-depth rackmount with 8 copper and 4 fiber ports fits dense deployments
  • Includes 3-year Xstream Protection subscription for zero-day threat defence

Questions about this item

Should I choose the 12 GB DDR4 system memory or the 4 GB DDR4 NPU memory for my workload?

The 12 GB DDR4 at 2666 MHz serves the main AMD x86 CPU for general firewall tasks, while the separate 4 GB DDR4 is dedicated to the Marvell NPU for flow processing; both are fixed and not user-selectable.

What does the 2.47 Gbps TLS inspection figure mean when the appliance is handling live encrypted traffic?

It represents the maximum sustained throughput for decrypting, inspecting, and re-encrypting TLS 1.3 sessions under test conditions; real-world throughput will be lower depending on cipher mix, session size, and concurrent connection count.

How do the 10GBase-X SFP+ ports and 10/100/1000Base-T copper ports cap throughput in practice?

The two SFP+ ports each support up to 10 Gbps fiber links, while the eight RJ-45 copper ports auto-negotiate at 10, 100, or 1000 Mbps; aggregate throughput is limited by the 47 Gbps firewall rating and 10.5 Gbps IPS rating.
