Vasu Gala - PeerSpot reviewer
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.
Gary-Downey - PeerSpot reviewer
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.
Alexander Azikov - PeerSpot reviewer
A robust appliance that is reasonably priced and straightforward to set up
Although manageable, the user interface is a little bit slow and could be improved. There are two user interface options available, namely the basic and the advanced. The basic UI is not very good and doesn't have a lot of features, although it is fast. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists. At one of our sites, the CPU utilization was very high, and for no reason. Technical support needs to be more responsive to requests.

Quotes from Members

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

Pros

"FortiGate Next Generation Firewall has a simple configuration."
"The most valuable features of Fortinet FortiGate are remote access, web filtering, and IPS."
"The scalability is easy with switches and access points that are basically plug-and-play for the most part."
"The CLI and GUI do a good job of putting a lot at your fingertips."
"FortiGate is a great solution, although initially, it faced challenges in the Brazilian market due to lower brand recognition than Cisco. However, explaining and demonstrating its product format and offerings has proven easy. The cost-effectiveness and better features of FortiGate have made some clients skeptical. We set up a trial period, and they eventually opted for it. Many clients were convinced it was great after experiencing the solution's capabilities firsthand."
"Easy to use support and licensing portal as well as activation process."
"The ease of setting the solution up is a valuable aspect for us."
"FortiGate Next Generation Firewall has a stateless balance proposition"
"The web blocking for my clients and the application control are valuable."
"It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall."
"Since it can be put on any box, the scalability is fantastic."
"Web filtering is very reliable."
"The solution's most valuable feature is the content filtering."
"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."
"The product is easy to implement."
"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."
"The solution can scale well."
"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

"The solution could be more user friendly."
"I'm not sure if it's something that they already have or are developing something, however, we need some dedicated features for container security."
"From my experience, I see that the datasheets of the Fortinet FortiGate portfolio need to be more accurate because correct sizing is essential. The datasheets should provide clear information when deploying features."
"I think there could be more QoS features"
"It is very expensive, and their support is not very good. I hope that their technical support will be better in the future."
"The solution can have more features in a single box that can be multi-applied to integrate everything."
"A couple of things I've seen that need improvement, especially in terms of a hard coding. The driver-level active moment really is out-of-the-box and we have to have contact the customer support and sometimes it is difficult to resolve."
"There's always something new that can be added or fixed."
"Whenever there are a large number of endpoint VPN clients, connectivity becomes slow."
"Web-filtering policies could be improved."
"For the web filter, I think they can do better especially on the free model."
"The management console for partners is a bit tricky (buggy)."
"The storage is minimal, so we have to set the system to delete data after seven days."
"The pricing is not as good as it was some time ago. They've since skipped offering a lot of individual features."
"We seek the availability of the hardware in our region. The hardware-based firewall from Untangle is currently not available in our region. It should have threat protection on a real-time basis. This feature, available in Check Point and Sandstorm kind of scenario, is currently missing in Untangle NG Firewall."
"The ability to setup a DDNS for each WAN independently would be a very handy feature."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
"Although manageable, the user interface is a little bit slow and could be improved."
 

Pricing and Cost Advice

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."
"I rate the product's pricing a seven out of ten. The additional cost depends on the extra feature requirements."
"The main reason we chose Fortinet FortiGate was that the price was better than the competition."
"It is too expensive for us. My organization is very small, and we have a total of ten users. We have three internal users and seven external users. The FortiGate 100D series is too expensive for renewing the licenses."
"I pay €1,200 per year for the license along with Fortinet's 81E firewall appliance. I would rate this pricing as 3/5 stars, and I believe the price is reasonably similar to its competitors in the market, being somewhere in the middle."
"The Fortinet FortiGate security features cost approximately $1,500 a year. The firewall itself doesn't have a recurring cost. It's the security features on top of that that you pay for."
"While slightly more affordable than competitors, it remains relatively expensive due to its inclusive subscription."
"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."
"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."
"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."
"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."
"For the home use, it's cheap."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
