A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

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.

User has benefited from stable performance and effective completion of security tasks
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

"Application control and the web filter are the best features of Fortinet FortiGate."
"The usage in general is pretty good."
"It's a good product that significantly enhances security and protects organizational data."
"The benefits Fortinet FortiGate provides include easy connectivity, user-friendliness, scalability, and easy configuration management."
"The most valuable feature of Fortinet FortiGate is the simple configuration."
"The pricing is excellent. It's much less expensive than Cisco."
"It's a user-friendly firewall. Most of the tasks are very simple. It's simple to configure and troubleshoot this firewall."
"It's very easy to set up, it's very easy to make policies and, for an organization, that means you don't need IT expert in firewalls. You just need to have somebody who knows a little bit of IT, and that's it. With other products, you need someone with a "Masters" degree in firewalls."
"The Untangle firewall is a software firewall, so it runs on generic hardware. We found that was probably the best feature, and it's why we chose it when we started using it three years ago."
"​It is very easy to deploy and monitor. ​"
"Easy to set up and easy to integrate."
"The all-in-one gateway security functions and the ability to install it on generic equipment stand out."
"The solution's most valuable feature is the content filtering."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
"The ease of use and the built-in and integrated features, including the apps that include OpenVPN, IPsec, and WireGuard VPN, are all built straight into Untangle NG Firewall."
"They have a command center that makes it easy to log into and see all of your appliances nationwide."
"This is a capable appliance and the standard features work well for us."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The solution can scale well."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
 

Cons

"Compared to some other products, the DLP is not at par for the moment."
"There could be more modifications."
"Application management can be improved."
"Their technical support could be improved a little bit in terms of responsiveness."
"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."
"I would like to see improvements in the IPS/IDS feature to enhance protection against attacks from attackers, including ransomware protection."
"Improvements for Fortinet FortiGate could be made by making it easier to implement on networks and simpler to add users and accounts that utilize this solution. That's basically the only challenge that I see."
"The AI part needs improvement to enhance its functionality."
"Whenever there are a large number of endpoint VPN clients, connectivity becomes slow."
"The product must improve its reporting features."
"The storage is minimal, so we have to set the system to delete data after seven days."
"The pricing should be reduced because it is expensive."
"They don't have any feature that allows you to drop the session."
"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."
"The management console for partners is a bit tricky (buggy)."
"The solution's licensing count could be improved."
"Although manageable, the user interface is a little bit slow and could be improved."
"The product has some scalability and data management issues where improvements are required."
"Sometimes it reboots when you least expect it, and that's the main issue."
 

Pricing and Cost Advice

"The product is expensive. I rate its pricing a six out of ten."
"Fortigate's pricing is competitive."
"The pricing for the product is alright."
"I rate the pricing an eight and a half on a scale of one to ten, where one is low, and ten is high."
"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."
"Fortinet FortiGate as a less expensive solution than Palo Alto."
"I rate the product's pricing a seven out of ten. The additional cost depends on the extra feature requirements."
"The solution is offered as an annual license."
"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 setup cost is about $2000 to $3000 per year."
"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."
"The tool's pricing is moderate, and licensing costs are yearly."
"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."
"It is not expensive. It is cheaper than Fortinet."
"For the home use, it's cheap."
"It is the most cost-effective to use."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."
