It’s hard to believe we’ve never reviewed a Sophos UTM (SG series) firewall. So let’s fix that, because what an important family of firewalls they are. We’ll start with the Sophos SG105 desktop firewall.

The SG105 is the entry-level appliance in the SG series, and it is hugely popular. It starts at around $400, and is available with 1-year, 3-year, and 5-year TotalProtect bundles at Corporate Armor. The SG series is Sophos’ range of easy-to-deploy, easy-to-manage appliances that can fit just about any network size – from home office to small business to enterprise.

The SG105 is well-known for superior visibility into risky activity, as well as the ability to stop both known and unknown threats quickly and effectively. When it comes to malware, the SG105 can see it, stop it, and secure it.

The SG family

The SG is a mature and extremely dependable platform. In a way similar to Meraki, they take a great deal of pride in how easy these appliances are to set up and manage. And no, “mature” isn’t a euphemism. There’s a reason the SG series are still going strong. The hardware is identical to the newer XG series. CPU, RAM, memory, ports, all the same. And, the XG is Sophos’ undeniable wave of the future. But an SG can easily be upgraded with XG (SFOS) firmware, and viola! You have an XG firewall. Read more about that here.

Why would I choose an SG over the newer XG models?

Maybe you would, maybe you wouldn’t. Remember, the differences are pretty small. But there is a modest savings between comparable models. In addition, the GUI can be a little slower in SFOS. Plus, notifications run more smoothly in UTM. This is likely a function of SG’s maturity compared to XG. As was stated earlier, XG is the future, and its SFOS firmware will be an overall improvement. Then again, it’s no problem to load that firmware on an SG firewall. And Sophos’ primary energies are in developing SFOS, not UTM so much.
