These powerful firewall appliances offer 1U performance with a desktop form factor and price. If you have a small business or branch offices to protect and are working on a tight budget, these models are the ideal choice. They are also available with integrated 802.11ac wireless LAN for optimal coverage and connectivity for your mobile workers. Built upon the latest Intel architecture, our software makes optimal use of the multi-core technology to provide excellent throughput for all your key processes.

These models come equipped with 8 GbE copper ports built-in, plus 1 SFP port, e.g. for use with our optional DSL modem or fiber connectivity using an SFP transceiver. An expansion bay provides the option to add additional connectivity such as our 3G/4G module. A 2nd Wi-Fi radio module is also available for the SG 135w. An optional second power supply ensures business continuity for these models. As with all our SG firewalls, up to 10 appliances can be dynamically clustered for greater scalability (must be the same model and revision number for HA).

With bandwidth requirements constantly increasing, network security appliances need to do more than ever before. The Sophos SG Series appliances are built to provide optimal performance, versatility and efficiency to meet all your security needs.

The Sophos SG Series appliances are designed to provide the optimal balance between performance and protection – for diverse IT environments. Whether you need a solution for a small remote office, want to protect your school campus, or are a global organization requiring high-availability and enterprise-grade features, our SG Series appliances are an ideal fit.


Appliances to suit every environment Our broad product line-up makes it easier for you to choose the right appliance. A higher model number indicates higher throughput and an increased number of ports or connectivity options.

And as every software subscription is available on every appliance, you can flexibly size the solution to fit your budget and your individual security needs. Next-generation firewall features or all-in-one security on a single box, it's your choice.


Proven performance on all models Our appliances are built upon the most advanced Intel technology. Optimized use of multi-core processors allows consolidation of your security solutions without a performance trade-off.

With faster than ever firewall, IPS and VPN throughput, our SG Series appliances effortlessly handle multiple tasks simultaneously. Plus, you can easily scale up by dynamically clustering up to 10 units without external load balancers.


Flexible configuration options on many models Configure your hardware to suit your infrastructure, even when that changes. Our optional FleXi Port LAN modules give you the freedom to select the connectivity you need – copper, fiber, 10GbE – you decide.

And because they're fully interchangeable between the mid-range models, if you do choose to upgrade to a larger appliance, you simply swap your old appliance's module to the new one.



Technology built to process data in real-time Your network is constantly changing so your protection needs to be adaptive. All our appliances have integrated high-speed hard drives (in many cases SSDs) for local storage of spam quarantine data and faster access to comprehensive reports and real-time logs.

Accelerated in-memory content scanning in secure proxy mode makes your defenses more effective and efficient.


Engineered for business – today and tomorrow Using the latest Intel technology, our products provide the maximum in flexibility to add to your protection as you need it - without changing or upgrading your hardware. So you benefit from future software and performance enhancements which guarantee the best possible value for your money. Our SG 450 offers unmatched enterprise-grade features for high-availability on a 1U rack-mountable appliance.
