Has provided built-in VPN tools and reporting features that streamline remote access and monitoring tasks
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 solution's most valuable feature is the content filtering."
"Untangle NG Firewall is something that I recommend, although we have only tried the software version."
"The flexibility to grow, the user-friendliness of the interface, and the common center facility are the advantages of Untangle NG Firewall."
"The all-in-one gateway security functions and the ability to install it on generic equipment stand out."
"The threat prevention features of Untangle NG Firewall have helped my network security management, and I find them very good."
"The reason we chose this solution is because of their support, which is hands down the best support that I have had with a firewall."
"The product is easy to implement."
"Web filtering is very reliable."
"The solution can scale well."
"The cost is very low."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"Whenever there are a large number of endpoint VPN clients, connectivity becomes slow."
"The product needs to improve its mobile application."
"For the web filter, I think they can do better especially on the free model."
"The common center facility that Untangle provides should be available on-premises. There are great corporations here in Mexico that like the Untangle solution, but they don't like the fact that the monitoring and access to the appliance are in the cloud. They request for the common center facility to be available and installed on-premises."
"The web content filtering needs improvement."
"The product must improve its reporting features."
"The hardware can be improved."
"We have a minor issue when assigning IP addresses in the ARP tables. You should be able to go into the ARP tables, look at the IP address and say, "Nope, they need to be on this side on this IP address." The ability to set a DHP reservation from the ARP tables would be great. It's no big deal, but it would be nice to have."
"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 integration capability is quite challenging. The system is very complicated, and many features are hidden."
"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."
 

Pricing and Cost Advice

"For the home use, it's cheap."
"The tool's pricing is moderate, and licensing costs are yearly."
"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."
"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 setup cost is about $2000 to $3000 per year."
"The solution is fairly priced."
"Untangle is open-source software. So, you can get it for free. That has been a benefit, especially for the residential users because it is free. The license costs start at $25 a month for some additional features, including higher tiers of security intrusion prevention. The free version comes with intrusion detection, and then the license version has intrusion prevention. It also has some additional things for active directory connectors, etc. It starts at $25 a month to cover 12 devices. Then it goes up from $25 to $50 a month for 12 to 25 devices. That's where it really doesn't scale out per site. If you have a site that has more than 50 devices on it, then Untangle quickly becomes cost prohibitive in comparison to several other competitors."
"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."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
