Sophos XGS4300 Firewall

Description

Sophos XGS4300 Firewall — Next-Generation Firewall

The Sophos XGS 4300 is a 1U next-generation firewall built for organizations that require high-performance network security with flexible interface expansion. It combines fixed 1GbE, 2.5GbE, and 10GbE interfaces with two Flexi Port slots.

The appliance delivers up to 75 Gbps firewall throughput, 29.5 Gbps IPS throughput, 25.2 Gbps threat protection throughput, and 23 Gbps NGFW throughput according to Sophos’ current published specifications.

Connectivity

The fixed interface configuration includes four Gigabit Ethernet copper ports, four 2.5GbE copper ports, and four 10GbE SFP+ fiber ports. Two of the Gigabit Ethernet pairs support bypass functionality.

This combination allows the XGS 4300 to connect to different network segments, uplinks, servers, switches, and other infrastructure without relying on a single interface speed.

Flexi Port Expansion

Two Flexi Port slots provide additional connectivity options. Sophos lists modules covering 8-port Gigabit copper, 8-port Gigabit SFP fiber, 4-port 10GbE SFP+ fiber, Gigabit copper bypass, PoE, 10GbE NBASE-T with 10GbE SFP+, and other configurations.

For the XGS 4300 and XGS 4500, Sophos also documents a Flexi Port module combining two 10GbE NBASE-T RJ45 ports with two 10GbE SFP+ ports. The ports can operate independently on these models, allowing different supported speeds to be configured across the four ports.

Security and Performance

The XGS 4300 provides high-capacity firewall processing alongside security inspection capabilities. Its published specifications include 16.6 million concurrent connections, 368,000 new connections per second, 62.5 Gbps IPsec VPN throughput, and 8 Gbps Xstream SSL/TLS inspection throughput.

Sophos XGS appliances use the Xstream architecture to offload qualifying processing workloads to dedicated hardware. Sophos documentation identifies the XGS 4300 as supporting acceleration for qualifying firewall, IPsec, and PKI workloads.

Rackmount Design

The XGS 4300 is designed for 1U rack installation. Its chassis measures 438 × 44 × 510 mm and weighs 8.7 kg unpacked. The appliance uses an internal auto-ranging AC-DC power supply and supports an external redundant PSU option.

Selection Guide

For High-Speed Firewall Deployment

Consider the XGS 4300 when the network requires high firewall throughput together with multiple 10GbE and multi-gigabit interfaces.

For 10GbE Connectivity

Use the four integrated SFP+ ports for compatible 10GbE fiber connections. Select the appropriate SFP/SFP+ transceiver based on the required fiber type, distance, and network equipment.

For Additional Ports

Use the two Flexi Port slots when additional interfaces or different media types are required.

For Multi-Gigabit Copper

Consider a compatible Flexi Port configuration when the deployment requires higher-speed copper connections. Sophos documents a 10GbE NBASE-T and SFP+ module for supported XGS models, including the XGS 4300.

For PoE Requirements

Compatible Flexi Port modules can provide PoE connectivity. Sophos lists support for up to four PoE ports at a maximum of 60 W each when using two compatible modules.

Always Verify

Confirm the exact hardware revision, supported Flexi Port module, transceiver compatibility, licensing requirements, and deployment requirements before purchasing.

Installation Notes

The Sophos XGS 4300 is designed for rackmount deployment. The supplied installation documentation identifies rackmount brackets and rails among the contents of the XGS 4300/4500 package.

Before installation, ensure that the rack provides sufficient depth and ventilation. Sophos specifies a minimum rack depth of 603 mm and a maximum rack depth of 930 mm for the XGS 4300/4500.

Connect the required network interfaces according to the planned topology. When using SFP/SFP+ modules, select compatible transceivers and patch cables that match the required media and distance.

Flexi Port modules should be installed according to Sophos hardware documentation. Verify the supported module and hardware revision before installation.

Best Practices

• Confirm the exact XGS 4300 hardware revision before purchasing expansion modules.
• Use compatible Sophos-listed SFP/SFP+ transceivers.
• Plan 10GbE uplinks according to distance and fiber type.
• Document the role of each physical interface.
• Label cables and interfaces for easier troubleshooting.
• Maintain adequate airflow around the 1U appliance.
• Verify Flexi Port compatibility before installation.
• Use redundant power options where the deployment requires additional power resilience.
• Keep firmware and security subscriptions current according to the organization’s Sophos deployment policy.
• Maintain configuration backups as part of the firewall administration process.

Benefits for IT Teams

The Sophos XGS 4300 provides a combination of fixed high-speed interfaces and modular expansion that can simplify network design for organizations with demanding connectivity requirements.

Its 1U form factor supports rack-based deployments, while the 10GbE SFP+ interfaces provide high-speed uplink options. The two Flexi Port slots allow IT teams to adapt interface density and media types to specific deployment requirements.

The platform also provides high published firewall, IPS, VPN, and SSL/TLS inspection performance, giving network teams a single security appliance for a broad range of enterprise edge and distributed network scenarios.
