The X G S Firewall
This is a dual-processor system that effectively detects and blocks attacks on your network and, in the event of a malware infection, isolates the affected device to prevent an outbreak across the network.
And thanks to the Xstream Flow Processor, which is a high-performance multi-core processor , all this is possible without compromising performance.
Detect. Defend. Protect.
The three pillars of the XGS Firewall that ensure your network stays secure.
Uncover risks
The XGS Firewall helps you identify risks in specific activities, highlight suspicious traffic and analyse complex threats. This gives you a clear view of your network again.
Block threats
This is where first-class protection technologies come into play. Deep Learning, a neural network that continuously evolves, and Intrusion Prevention provide targeted defence against malware and intruders.
Isolate infected systems
If an infection occurs, the firewall responds automatically, isolating the compromised system and protecting the network from further spread.
Exceptional performance with full protection
The X G S - appliances come with the new Sophos Firewall Operating System (SFOS) in version 18.5 and use their dedicated Xstream Flow Processors to accelerate applications, perform TLS inspection at peak performance and deliver powerful threat protection.
The Sophos Firewall's Xstream architecture is designed to provide an incredible level of visibility and protection without having to worry about performance losses. This ensures your network can withstand today's threats with ease.

TLS 1.3 Inspection
We can put those concerns to rest: the Sophos Firewall can inspect encrypted traffic with ease, so users and administrators notice no difference, despite the tremendous increase in security!
Deep Packet Inspection
Sophos Firewall prevents the spread of the latest ransomware and blocks exploits with high-performance streaming DPI, complemented by next-generation Intrusion Prevention, web protection and Application Control , as well as Deep Learning and sandboxing powered by SophosLabs Latrix.
Application acceleration
Accelerate business application traffic to improve your workflow.
Traffic for branch offices, cloud application servers or remote users matters most to your business. And this trusted traffic naturally needs no malware scanning. This data can therefore be intelligently routed through FastPath. This dramatically reduces latency and optimises overall performance, allowing processing power to focus on the threats that matter.
The new Xstream Flow Processors allow traffic such as VoiP, video, SaaS, SD-WAN and other trusted applications to be routed through FastPath automatically or via configurable policies.
