We do an outside-sourced threat prevention regarding the Threat Prevention features. I haven't run into areas that could be improved or cons versus pros for Untangle NG Firewall. I haven't done anything too advanced when it comes to the filtering, so I'm not sure what can be improved or added. 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. These areas could be improved to make it a nine out of 10 or a 10 out of 10 for overall rating.

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The Untangle firewall is a software firewall, so it runs on generic hardware, and we found that was probably the best feature, and it's why we chose it when we started using it three years ago."
"Application Control and filtering features are valuable."
"Its detection, antivirus, and filtering features are the most valuable. The facility to connect by using the VPN connection is also a very valuable feature. It is very strong, secure, and reliable. We have implemented the Untangle solution in all hardware. It is also a user-friendly solution. It is easy to learn and easy to configure."
"The threat prevention features of Untangle NG Firewall have helped my network security management, and I find them very good."
"Untangle NG Firewall is something that I recommend, although we have only tried the software version."
"It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall."
"The solution's most valuable feature is the content filtering."
"What I like about this product, which is the reason that we continue to use it, is that you can install the software version on your own hardware. In case there is a problem with the hardware, we can just install the firewall in another machine and restore the configuration."
"This is a capable appliance and the standard features work well for us."
"The solution can scale well."
"The cost is very low."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"They don't have any feature that allows you to drop the session."
"The biggest challenge that we have with this solution is local support. The local support is a problem in our area."
"The product should improve reporting."
"The local technical support does not understand the product very well."
"The product needs to improve its mobile application."
"There is room for improvement in the logs. Like with Cisco, I can do almost everything and know almost anything about what's running. Untangle works very much out of the box. It's very user-friendly, but it's not engineer-friendly. So, it's good for a home user. For something fairly easy, but at the same time, with good technology to have at home, because at home, I'm not a millionaire or anything like that. So it's not like I'm worried to get hacked. I didn't want something like a Cisco firewall; it would be a bit overkill to have at home. So that's why I went for Untangle. But it lacks a few features. It's just a tick-box kind of thing. So they have apps and turn on and off the apps. The VPN's configuration is all very ticked. They have a few custom configurations, but it's not that much."
"I do not know if I have seen any return on investment. It might be a little expensive if I need to make an external firewall or at my sites like DNS and web zones."
"The storage is minimal, so we have to set the system to delete data after seven days."
"Sometimes it reboots when you least expect it, and that's the main issue."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"The product has some scalability and data management issues where improvements are required."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"The integration capability is quite challenging. The system is very complicated, and many features are hidden."
 

Pricing and Cost Advice

"The pricing model is better than with SonicWall."
"We pay $350 USD per year for the solution. There are no additional costs. As long as you're not using a physical appliance, that's all you need."
"Usually, it's about $350 a year for 12 users, and it's about $600 for 50 users. It's very reasonable as compared to the others. One of the reasons is that they're all open-source. You just buy their appliance and put it in until it dies. Because it's run under open platforms, mine seems to always work on older equipment. I've taken old equipment and put a new hard disk in it. I have taken about nine-year-old computers and put their operating system on them, and ran them like a champ. The only thing that changed was the hard drive because I don't trust a hard drive that's more than three to four years old."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."
"The solution is fairly priced."
"It is not expensive. It is cheaper than Fortinet."
"This is not an expensive product. It is affordable and there are different packages available depending on the features that you need, or the sector that you are in."
"It is not expensive. The best part is that it is based on the pay-per-use kind of scenario. An increase or decrease in the number of people doesn't make any difference. We are really happy about using this particular scenario."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
