Pros
"The performance is good.""The features that we have found most valuable are the SSL VPN and the User Portal.""The technical support in our region is excellent.""Whenever we raise a complaint with FortiGate, their response and resolution times are minimal.""It is a safe product.""Valuable features include the Web Application Firewall, and it even has DLP (data leak prevention).""Whenever I need something, Fortinet improves and updates the software for me.""It performs very well."

More Fortinet FortiGate Pros →

"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed.""OPNsense is easy to scale when running on the hardware.""OPNsense is highly stable.""What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted.""The most valuable features of OPNsense are the GUI and frequent updates.""It has firewall and VPN capabilities, which are very valuable features.""OPNsense is easy to use and open source.""It has an open license. It works very well, and there is an update every month."

More OPNsense Pros →

"NG Firewalls allow us to permit or deny applications we don't want to run. We also use content filtering, SSL inspection, and all the other things we run on the firewall to keep our clients protected and ensure they're not going where they shouldn't. It's a great firewall that works as intended.""The web blocking for my clients and the application control are valuable.""The most valuable features are IPS, MAPI, NAT, and VPN.""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 product helps small and medium enterprises secure their networks from intrusions. It also has features like DNS blocking.""It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall.""They have a command center that makes it easy to log into and see all of your appliances nationwide.""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."

Cons
"We were not able to build a full-mesh VPN; however, I am not sure if this was the fault of Fortinet FortiGate.""Fortinet FortiGate can be integrated with different platforms. They have integrations in place, but I can't say they're 100%.""Stability and technical support are the two major issues I have found with Fortinet.""I think they need to improve more in order to be a competitor with the leaders of the field.""Fortinet FortiGate could improve the user interface. There should be more functionality and options through the GUI.""The setup is pretty complex and not easy to implement.""Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem.""FortiLink is the interface on the firewall that allows you to extend switch management across all of your switches in the network. The problem with it is that you can't use multiple interfaces unless you set them up in a lag. Only then you can run them. So, it forces you to use a core type of switch to propagate that management out to the rest of the switches, and then it is running the case at 200. It leaves you with 18 ports on the firewall because it is also a layer-three router that could also be used as a switch, but as soon as you do that, you can't really use them. They could do a little bit more clean up in the way the stacking interface works. Some use cases and the documentation on the FortiLink checking interface are a little outdated. I can find stuff on version 5 or more, but it is hard to find information on some of the newer firmware. The biggest thing I would like to see is some improvement in the switch management feature. I would like to be able to relegate some of the ports, which are on the firewall itself, to act as a switch to take advantage of those ports. Some of these firewalls have clarity ports on them. If I can use those, it would mean that I need to buy two less switches, which saves time. I get why they don't, but I would still like to see it because it would save a little bit of space in the server rack."

More Fortinet FortiGate Cons →

"The user interface could be improved, and the DNS section should be more intuitive.""On the customer-side, because I'm a small business, I need a cheaper or free solution option.""When using the solution at the beginning was difficult. There was a steep learning curve.""OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server.""There are issues with stability and reliability.""The logging could improve in OPNsense.""The support for OPNsense is good because we have documents available on the internet. The support could improve a little.""They should improve IPEs for security in the future."

More OPNsense Cons →

"It would be much easier if there was a mobile app.""The management console for partners is a bit tricky (buggy).""The product must improve its reporting features.""The biggest challenge that we have with this solution is local support. The local support is a problem in our area.""The web content filtering needs improvement.""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 product should improve reporting.""The product needs to have a better support group for its online support, specifically for its help desk."

Pricing and Cost Advice
  • "Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."
  • "These boxes are not that expensive compared to what they can do, their functionality, and the reporting you receive. Fortinet licensing is straightforward and less confusing compared to Cisco."
  • "Go for long term pricing negotiated at the time of purchase."
  • "Work through partners for the best pricing."
  • "The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."
  • "Easy to understand licensing requirements."
  • "​We saved a bundle by not needing all the past appliances from an NGFW.​"
  • "The cost is too high... They have to focus on more features with less cost for the customer. If you see the market, where it's going, there are a lot of players offering more features for less cost."
  • More Fortinet FortiGate Pricing and Cost Advice →

  • "We are not paying any licensing fees. OPNsense is completely free for us."
  • "It costs about $1000."
  • "There are no licensing costs for OPNsence."
  • "OPNsense is open source software so at this time it is free for us to use."
  • "OPNsense is a well known open-source tool."
  • "It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
  • "OPNsense is an open-source solution and it is free to use."
  • "The solution is not expensive."
  • More OPNsense Pricing and Cost Advice →

  • "It is the most cost-effective to use."
  • "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."
  • "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."
  • "It is not expensive. It is cheaper than Fortinet."
  • "The pricing model is better than with SonicWall."
  • "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."
  • "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."
  • "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."

    Reviews from Real Users

    Untangle NG Firewall is a solution that stands out when compared to many of its competitors. Some of its major advantages are that it is easy to use, has good features, including VPN, reporting, alerting, and filtering, and can be installed on existing hardware.

    “It is very easy to use. The user interface is very straightforward. It may not be as fancy as some of the ones I've seen, but it's very straightforward. It's very easy to find what you need, and it's very easy to get things done,” says Josh E., CEO at DragonTech IT Services, Inc.

    Barry A., Owner at ThinkEzIT, says, “It has good VPN features, helpful reporting and alerting, built-in content filtering, and excellent support.”

    PeerSpot user Victor O., Director at Kisii County Government, explains, “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.”
