Sophos XGS 108

Description

Sophos XGS 108

The Sophos XGS 108 is a 2nd-generation desktop firewall appliance designed for organizations that need strong network security without moving to a larger rackmount firewall platform. It combines a compact, fanless form factor with high-speed 2.5GbE connectivity and advanced security processing.

With up to 12.5 Gbps firewall throughput, 8.1 Gbps firewall IMIX performance, 2.5 Gbps IPS throughput, and 8.25 Gbps IPsec VPN throughput, the XGS 108 is positioned for demanding SMB and branch-office security deployments.

Connectivity Category

The appliance includes six 2.5GbE copper interfaces and one SFP fiber interface. This combination allows organizations to connect modern multi-gigabit LAN infrastructure while retaining the option of fiber-based connectivity.

The XGS 108 also includes one RJ45 COM interface, one Micro-USB COM interface, one front USB 2.0 port, and one rear USB 3.0 port for management and peripheral connectivity.

Security Performance

Sophos rates the XGS 108 at up to 2.5 Gbps for IPS and threat protection, 2.6 Gbps for NGFW, and 800 Mbps for Xstream SSL/TLS inspection. These capabilities allow the appliance to inspect and protect traffic while supporting encrypted connections and advanced firewall services.

Why Choose the Sophos XGS 108?

The XGS 108 combines high-speed multi-gigabit interfaces, strong security throughput, silent fanless operation, optional power redundancy, and rackmount flexibility in a compact platform. It is particularly suited to organizations upgrading from Gigabit-only firewall infrastructure to a modern 2.5GbE network.

Selection Guide

For SMB or Branch Networks

Choose the XGS 108 when you need a compact next-generation firewall with multiple 2.5GbE ports and advanced security processing.

For Multi-Gigabit Networks

The six 2.5GbE copper interfaces make the XGS 108 suitable for networks built around 2.5GbE switches, access points, servers, and other high-speed devices.

For Fiber Connectivity

Use the integrated SFP interface with a compatible Sophos-supported transceiver when a fiber uplink is required.

For Rack Installation

Select the optional rackmount solution when the XGS 108 needs to be installed in a standard network rack. The supplied Sophos accessory reference identifies the RM-SR-T15 Series for XGS 108 rack installation.

For Power Redundancy

Consider the optional second power supply for installations where continued operation during a single power-supply failure is important.

Always Verify

Confirm the exact XGS 108 generation, required transceiver, rackmount kit, and power accessory against current Sophos compatibility documentation before purchasing.

Installation Notes

The Sophos XGS 108 can be installed as a desktop appliance or mounted using an appropriate rackmount solution. Its dimensions are approximately 260 × 180 × 44 mm, with an unpacked weight of approximately 1.8 kg. The appliance supports wall, rack, and DIN-rail mounting options according to Sophos operating instructions.

For network installation, connect the 2.5GbE copper interfaces to compatible network equipment and install the appropriate SFP transceiver when using the fiber interface. Transceivers are sold separately.

The XGS 108 uses an external auto-ranging AC-DC power supply rated at 100–240 VAC and 60 W output. If an optional second power supply is used, follow Sophos installation guidance for the supported configuration.

Best Practices

Use appropriate 2.5GbE cabling and compatible network equipment for multi-gigabit connections. Prefer Sophos-supported transceivers for the SFP interface. Provide adequate airflow around the appliance even though the XGS 108 is fanless. For rack deployments, use the model-specific rackmount solution rather than a generic shelf.

For critical deployments, consider the optional second power supply. Label network interfaces and document the firewall’s connections to simplify maintenance and troubleshooting.

Benefits for IT Teams

High-speed 2.5GbE connectivity simplifies deployment in modern networks. Fanless operation reduces noise in office environments. The integrated SFP interface provides fiber connectivity without requiring an external media converter. Optional power redundancy supports higher-availability deployments.

The compact form factor also gives IT teams flexibility to deploy the same firewall platform in desktop, branch-office, wall-mounted, DIN-rail, or rack-mounted environments.
