The Sophos XGS 138 Security Firewall Appliance is a powerful, second-generation desktop solution designed for SMB and branch-office environments. Featuring a dual-processor architecture with a dedicated Xstream Flow processor, it provides hardware acceleration for superior network performance. With an impressive firewall throughput of up to 19.1 Gbps, IPS throughput of 5.85 Gbps, and IPsec VPN throughput of 6.6 Gbps, this appliance handles heavy security loads efficiently.

Connectivity is a standout feature: it includes 4x1 GbE copper ports, 2x2.5 GbE ports with PoE support (802.3at, 30W max per port) for high-speed wired connections, and 2x10 Gb SFP+ fiber ports for ultra-fast fiber network integration. The XGS 138 supports modular expansion with a dedicated slot for optional modules like a 5G failover, plus optional redundant power supply for enhanced reliability.

The device incorporates USB 2.0 (front) and USB 3.0 (rear) ports and multiple management interfaces, including COM RJ45 and Micro-USB. Energy efficiency improvements reduce power consumption by up to 50% compared to the first-generation models, while integrated storage (64GB SSD reported) helps with local logs and quarantine.

Running on Sophos Firewall OS (SFOS) version 21 or later, this appliance benefits from advanced threat protection, accelerated VPN performance, and comprehensive security features, making it a robust solution to safeguard distributed branch networks.
