All XGS Series firewall appliances are based on a dual-processor architecture that combines a high-performance multi-core CPU with a dedicated Xstream flow processor for targeted hardware-level acceleration. This gives you the flexibility and adaptability of an x86-based firewall, as well as a significant performance boost over legacy firewall designs. The desktop appliances are the ideal choice for customers looking for an all-in-one network security solution with seamless connectivity. With the modularity that small businesses, retail and branch offices need to grow and adapt to change, our desktop appliances offer the perfect price/performance ratio. All desktop models are optionally available with integrated WLAN. All models are equipped with a high-speed CPU and dedicated Xstream Flow processor for powerful hardware acceleration. Sophos Firewall's Xstream architecture is designed to provide extremely high levels of visibility, protection and performance, enabling administrators to easily meet the toughest challenges of today's networks. An expansion slot on all XGS-116/126/136 models improves compatibility for 3G/4G when used with an optional module.
