Room For Improvement

OPNsense users face VPN setup issues, inadequate documentation, performance shortfalls, high pricing, and request better usability and features.
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.
Enhancing its performance for significant amounts of data traffic would make it closer to a perfect solution.
Senior Network Engineer at a comms service provider with 11-50 employees
It would be beneficial if they could create some videos on how to set it up themselves.
Administrator at a retailer with 10,001+ employees
The documentation should be clearer because I faced some difficulties navigating many options.
ISO 27001 Lead Implementer at a consultancy with 11-50 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.
Network and Infrastructure Manager at Sonysugar
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

OPNsense is a cost-effective, open-source solution for enterprises, reducing expenses compared to FortiGate and Palo Alto alternatives.
Sophos UTM provides flexible, cost-effective licensing with some complexity, making it valuable for enterprises despite pricing concerns.
Untangle NG Firewall's modular pricing varies with setup size, offering cost-effective open-source options and flexible enterprise packages.
I consider the pricing of OPNsense to be high when compared with other market products.
Senior Network Engineer at a comms service provider with 11-50 employees
OPNsense is free, the licensing and setup was easy.
Administrator at a retailer with 10,001+ employees
Pricing has become expensive recently due to the dollar hike and naira value changes in Nigeria.
Associate Director - Management Support Services at CIHP
The value between what I receive and what I pay is the best in the industry.
System Administrator at a training & coaching company with 11-50 employees
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.
Network and Infrastructure Manager at Sonysugar
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.
Information Technology System Administrator at Ίδρυμα Ευγενίδου / Eugenides Foundation

IT Manager at a comms service provider with 201-500 employees
Open-source firewall has provided affordable real-time protection and secure remote access
In my opinion, OPNsense could improve by incorporating either an open side of wireless management or a way that you can also manage your interconnected devices. You could easily have SNMP, Simple Network Management Protocol, incorporated in it so that you can easily manage the devices and easily get the information about the devices that you are managing. Additionally, the inclusion of Pi-hole would allow you to create an ad-free network instead of adding it on a separate device. I would prefer that incorporated into OPNsense, or if it is there, I would appreciate guidance on how to use it.

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…
