The Sophos UTM is a UTM and Sophos XG is the NGFW. First, you must know about the difference between a UTM and NGFW. They can not be compared with each other because the price, license, firewall throughput, and TLS Inspection are completely different.

You can see the Sophos UTM brochure in this link:https://sophosfirewall.ir/wp-c...

The biggest difference between Sophos SG and Sophos XG is performance. 

Now, there's even a newer Hardware Platform (same OS as Sophos XG, which is called SFOS) - the Sophos XGS which has different chipset architecture, to attend each security module, with its newest feature called XStream Technology. 

Besides that, the GUI is very different. Nevertheless, it's worth trying the Sophos XG or XGS, since its GUI is getting overhauled for better performance and easier management, by each new release.

Sophos UTM is no longer being developed, according to our reseller. All the development effort is going into XG. So XG will be the only Sophos firewall going forward, UTM will eventually be end of life.

The new appliances XGS have a dedicated streaming CPU (Xstream), in addition to the main CPU.

I have personally tested the differences between the XG and XGS similar appliances. The result is spectacular. 30% more perf minimum:


The UTM-9 is soon end-life. Sophos security staff is now focused on SFOS 18, XG, XGS.

To respond to the question "the biggest difference", I think is the "Synchronized Security":


The firewall is one of the full security solutions centralized in Sophos Central:


At most of our customers, we implement a Sophos Endpoint locally on servers and workstations and firewall XGS. The synchronized security interact between firewall and endpoints. This can resolve the problem with the "lateral movement" of an infected computer. It can isolate a computer from the network when detected as infected:


It can be extended to secure cloud systems with Sophos ClouOptix:


Tested with VM in AWS and Azure, work 5*!

Another big difference is the Webserver Application Firewall. All my customers with an internal webserver to be published in the net are protected with this "reverse proxy" (WAF). It really does the job of protecting IIS, Apache, etc. from externals attacks.

Another trick is the SSL VPN sites to sites. When a branch office is implemented with a front ISP router, sometimes the NAT traversal is not possible, for IPSEC VPN connections (UDP 500). With this SSL VPN,  Simple NAT works and gives an SSL 128-bit AES encryption.

Finally, I have a lot of experience in implementing UTM and, now, XG(S). No way, the log is a big difference, easier to use as in Fortigates! It is similar to CheckPoint firewalls.

For my experience, no way: -> Sophos XG(S)

My understanding is that UTM is the software; SG is the hardware. You can buy Sophos UTM running on SG hardware and then later upgrade to the XG running on the same hardware.

I've been told by our Sophos reseller that Sophos are pushing the XG as next generation firewall, and developing it to at least as good as UTM. So XG will be the firewall of choice moving forward. UTM will not be developed further, according to him.

To my understanding, UTM and XG are from different legacy companies that
are now owned my Sophos. During my time researching anti-virus, UTM makes
more sense for our needs seeing as XG is primarily a firewall. From the
information I was able to find during the time of research, it seemed most
of the community felt XG had feature gaps from UTM.

UTM specifically SG series is a very mature and stable platform. It lacks some of the new features of XG; however has a very strong feature set. If you are looking for stability, ease of use and something well documented and understood than I suggest going this way. If however you are looking for a strong level of integration and have a greater than 3 year horizon then I suggest XG.

Wifi integration for example works better on the new platform.

There are several differences since there are 2 versions, 

XG firewall has integrations with other products like intercept X and admin from Sophos central. 

SG UTM has less integration since it's a separate product. It was formerly Astaro firewall, but the most advanced features have been only set to the XG. 

There are appliance and software versions of both products. Depending on your need you might choose one or another. But basically, look at them as 2 different firewalls.

In my company, we use UTM Sophos and I am satisfied with it, but I didn’t use Sophos XG series (but as I heard it is great too).

Sophos UTM is the universal threat manager, XG is just the hardware firewall. In other words, UTM is the full package: A/V, application control, security heartbeat, IDS/IPS, etc. It's been a couple years since I've seriously used them, but I liked them at the time and I'm sure it's only gotten better since then.

What is the biggest difference between Sophos UTM and Sophos XG? UTM will die and XG will live.

Which of these two solutions would you recommend to a colleague evaluating firewalls and why? XG. SG is obsolete solution. No more development as it is on XG.

If you don't need waf and email protection .. XG/SFOS is the best, but if you need email protection and WAF... SG/UTM 9 is the best.
