Sophos UTM requires enhancements in user management, scalability, and interface while improving security features, flexibility, and centralized management.
Untangle NG Firewall needs improved support, a streamlined console, and enhanced features like web filtering, mobile access, and reporting.
You should not look just at a data sheet, but also look at real tests in the field and load tests from companies who are making them.
Founder at a tech services company with 11-50 employees
The API needs better integration to match accounts and objects more effectively.
Senior Network Consultant at Visionet Systems Inc.
Now, these features require separate products like FortiManager, FortiAnalyzer, and a FortiCloud subscription for reporting.
Chief Executive Officer at a tech services company with 1-10 employees
If you want to really implement some rules that are a little bit more difficult, Sophos always recommends getting the dedicated WAF, or web application firewall, but I would prefer to have more features on the web application firewall in the firewall itself because it would make more sense.
System Engineer SDDC / VCF at a tech services company with 51-200 employees
I would prefer to see additional features in the next release of Sophos UTM because cyber crime increases every day, so we also need to improve our game to prevent any chances for intrusion.

In Sophos UTM, we could define IP hosts and use this IP host.
CEO at iSource GmbH
The user interface, training, and general product innovation need improvement.
Service Delivery Manager at CasCom
I haven't dug into the advanced features, but I think some of the advanced capabilities are probably where it lacks a little bit, with the filtering and firewall rules.
Director of Information Technology at a consultancy with 11-50 employees
I would like to improve the ad blocker and SSL Inspector by having more settings in the filters, cookie filters, and pass lists.
Information Technology System Administrator at Ίδρυμα Ευγενίδου / Eugenides Foundation
 

Setup Cost

Fortinet FortiGate-VM offers competitive pricing with flexible licensing, appealing to medium-large enterprises but challenging for smaller firms.

I don't have this experience with Fortinet FortiGate-VM because my colleagues in Germany are reaching better prices than me.

Associate Director - Management Support Services at CIHP
The value between what I receive and what I pay is the best in the industry.

The pricing would be more economical if sold directly to the user compared to going through a partner, as they need to take their percentage.

It's less expensive, especially because it has a lot of the pieces integrated into the firewall, so you get savings on that front.
Director of Information Technology at a consultancy with 11-50 employees
It is not very expensive, so it is affordable for my budget.

Unified security fabric has simplified multi-country deployments and strengthened threat response
FortiGate VM delivers exceptional performance and security with no degradation of service or protection (same features as the HW option). As part of the Fortinet Security Fabric, it extends across clouds and distributed locations, mitigating blind spots in virtual infrastructures. FortiGate VM can be rapidly deployed, managed through a centralized platform, and offers a range of purchasing options to suit every need. Also, FortiGate VM offers versatile deployment options across both public and private clouds, supporting all major public clouds including AWS, Azure, and Google as well as most hypervisors such as VMware, Hyper-V, and KVM. These deployments enable organizations to create scalable, high-performance firewalls that can be tailored to different virtualized environments and hyper-scale public cloud infrastructures. FortiGate VM integrates seamlessly with various infrastructure as code (IaC) tools such as Jenkins and GitLab, supporting security as code practices.

Integrated security tools have supported critical infrastructure and improved network performance
Regarding Secureworks Taegis VDR Vulnerability Management, I do not have all these shortcuts in my head. Perhaps I have to ask my technicians, but we are in full stress because we have to change this entire firewall equipment, also the entire access points, because of the end of life. We also have the full product in for XDR and extensions. We are also part of the webinars from Sophos. It would be better if there were also some important webinars in German. Everything needs improvement, because also the wireless, also RED box and so on. The handling was much easier on the old equipment than on the new XGS. I think there should also be a little more automatic for SD-WAN routing and so on. Because we have to learn some things from the basic completely new because it is different than Sophos UTM, the XGS. The features that could be improved about Sophos UTM include the new features we have in XGS with a simpler interface. For example, in Sophos UTM, we could define IP hosts and use this IP host. We did not have to insert on every, for example, for wide area networks, we had to put the IP addresses from the other side by hand. In Sophos UTM, we could define it under definitions and then use this IP host where we needed it. In the new XGS, if there is a change in the IP address, we have to do it on all, for example, site-to-site VPN tunnels and so on. We have much more work and it is not so easy because we have to check all the definitions. It is also, for example, some of the male technicians like me, we have a biology handicap. For example, male technicians in Europe also have a red-green problem. So we use these light colors on the interface. In some cases, it is not easy to see the, for example, letters or numbers because of the contrast.

Firewall and VPN have strengthened security and now provide reliable bandwidth control
The impact of high-performance packet inspection on network performance metrics is very good. My network has good performance with very low CPU and memory usage. Real-time alerts from Untangle NG Firewall are important for me because every alert I have is sent to my email. The impact of these real-time alerts on my productivity is significant, as I may not be present, but I receive notifications about any problems in my WANs or network and sent to my emails, or something the firewall blocks. I would rate Untangle NG Firewall as an eight overall, considering all the features and capabilities.

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
