Sophos Redundant Power Supply (for XGS 4500 only) – XS4ETCHPS

Powerful Protection & Performance

Sophos Firewall and the XGS Series appliances with dedicated Xstream Flow Processors enable the ultimate in application acceleration, high-performance TLS inspection, and powerful threat protection. The Sophos Firewall Xstream architecture is engineered to deliver extreme levels of visibility, protection, and performance to help address some of the greatest challenges facing network administrators today.

TLS 1.3 Inspection

According to the latest statistics, approximately 90% of web traffic is encrypted, making it invisible to most firewalls. An increasing amount of malware and potentially unwanted apps exploit the fact that organizations are simply not using SSL inspection. Network administrators’ main fears are that SSL inspection will have a performance impact or cause something to break, impacting the user experience.

Sophos Firewall removes the blind spots caused by encrypted traffic by allowing you to use SSL inspection while maintaining performance efficiency.

Application Acceleration

A significant portion of your network traffic is important business application traffic destined for branch offices, remote users, or cloud application servers. This trusted traffic, which needs no additional security scanning for threats or malware, can be intelligently directed to the FastPath, reducing latency, and optimizing overall performance. This provides added capacity and headroom for traffic that does need deep packet inspection.

Sophos Firewall accelerates your SaaS, SD-WAN, and cloud traffic such as VoIP, video, and other trusted applications automatically or via your own policies – putting them on the FastPath through the new Xstream Flow Processors.

Deep Packet Inspection

We believe you should never have to decide between security and performance. Sophos Firewall includes a highspeed deep packet inspection (DPI) engine to scan your traffic for threats without a proxy slowing down the process.

The firewall stack can completely offload the processing to the DPI engine, significantly reducing latency and so improving overall efficiency. Sophos Firewall blocks the latest ransomware and breaches with high-performance streaming DPI including next-gen IPS, web protection, and app control, as well as deep learning and sandboxing powered by SophosLabs Intelix.
