What is the Sophos XGS Firewall 3100?
The Sophos XGS firewall 3100 is a next-gen firewall at its core, supporting advanced security functions like streaming DPI, TLS 1.3 inspection, AI-driven threat analysis, and more. It’s primarily designed for mid-sized enterprises that need some flexibility, as the Sophos firewall is able to support anywhere from 500 to 750 users.
Here’s a quick glance at what else you can expect from this next-gen firewall:
- Leverages Xstream architecture to balance traffic acceleration and deep inspection
- Delivers up to 38 Gbps firewall throughput
- Uses traffic offloading to maintain performance during intensive inspection workloads
- Optimized for hybrid and distributed networks that require consistent visibility and control
The list gets a lot longer from there. However, it’s important to dive into the performance architecture before you break down technical specifications. This is what helps to paint the full picture outside of specs alone.
Sophos XGS Firewalls Performance Architecture
With the benefit of Sophos Xstream protection, the 3100 is able to optimize how traffic is processed as well as prioritized. Moreover, it will offload aspects like trusted traffic, VPN flows, and cryptographic tasks to preserve inspection resources.
On the other hand, Xsteam protection works to allocate more processing power to high-risk and unknown traffic that requires deep packet inspection (DPI). Aside from the standalone benefits of XGS performance architecture, each next-gen layer complements the firewall as a whole.
Xstream Architecture and Traffic Offloading
Through the Xstream architecture, traffic is classified on angles like trust level, risk, and processing demands. This is all done before inspections begins.
In the full scope of Xstream, you get the assurance of consistent performance on top of reduced latency. This is also guaranteed even under a heavy network load. It’s just another component that highlights why this firewall device is built for the needs of growing enterprises.
Streaming DPI Engine
The XGS 3100 makes use of a Streaming DPI engine, which is crucial for real-time traffic inspection. It performs DPI as traffic flows, and this is done without waiting for full session reconstruction.
In addition to that, the firewall eliminates proxy-based inspection bottlenecks that are commonly found in traditional firewall architectures. The 3100 is able to maintain performance while running advanced security features, and scales efficiently at the same time. Overall, your network gets consistent throughput and user experience, even under heavy inspection.
High-Speed TLS 1.3 Inspection
Aside from secure, encrypted traffic, TLS 1.3 helps with decrypting encrypted sessions in real time for deep traffic analysis. Even more so, it works to detect threats that may be hidden inside encrypted application traffic.
It also helps to understand that TLS 1.3 inspection minimizes performance impact through the processes of optimized processing and hardware acceleration. In short, it’s a big part of ensuring you get full visibility without having to make any sacrifices in performance.
Key Specifications of the XGS 3100 Sophos Firewall
While 28 Gbps of firewall throughput is pretty impressive on its own, this is just the start of what the XGS 3100 is capable of. The premise of this firewall isn’t to just maintain performance but optimize for consistent security enforcement without the worry of network bottlenecks. The table below offers some direct insight into the key specifications of this firewall.

If it isn’t already clear, the XGS 3100 handles modern workloads from cloud apps, hybrid networks, and remote users without any issue. It can easily serve as a standalone core security control point for mid-sized organizations. Especially those needing a combination of scalable and resilient network protection.
Feature Highlights of the XGS 3100
Sophos Xstream protection and the specifications mentioned above aren’t all the XGS 3100 has to offer. Beyond perimeter defense, the firewall actively participates in threat containment, as well as remediation.
Here are several feature highlights you should know about:
- Automatically isolates infected devices to limit the spread of threats
- Blocks lateral movement across the internal network to contain breaches
- Prevents outbound communication used for data exfiltration or command-and-control traffic
- Easily integrates with Sophos Central MDR and XDR services for 24/7 monitoring and centralized incident response
- Shares telemetry between endpoints and the firewall for unified visibility and enforcement
Here’s the thing, maximizing the value of Sophos XGS firewalls comes down to proper deployment, setup, and ongoing management. Advanced firewall capabilities are great, but they require continuous optimization to stay aligned with shifting network demands. That’s why many businesses opt for managed services, as it takes all of the stress and guesswork out of the equation.
When to Consider Managed Services for Your Sophos XGS Firewall
This may not be the case for all businesses, but many lack the ability to handle 24/7 monitoring and response internally. In reality, any modern security environment requires constant oversight that goes beyond standard business hours.
With the likes of managed firewall services, you can entirely outsource firewall operations and maintenance. This includes a range of support from continuous monitoring, expert management, policy tuning, hardware updates, and overall ongoing support.
You might think this is a small business solution, but it’s viable for businesses of any size looking to prioritize their time and money. Managing network security can take quite a bit of time and manpower, and managed services help to alleviate a lot of the challenges in this arena. That means you can operate day-to-day knowing your XGS 3100 is in good hands, continues to scale with you, and your business network can adapt when it needs to.
Let’s Wrap Up
The Sophos XGS firewall 3100 is the perfect solution for mid-sized and growing organizations. With the combination of high-throughput processing, Xstream architecture, feature-rich functionality, and impressive specs, it’s a reliable choice to say the least.
Not only does it deliver strong real-world performance, but it’s suitable for hybrid environments, as well as cloud spaces, remote users, and handling encrypted traffic.
