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.

Thorough with all-in-one security functions and good affordability
The all-in-one gateway security functions and the ability to install it on generic equipment stand out. The centralized management console is great. I can template my installations and configurations. My ability to monetize it as a gateway security appliance to offer enhanced service offerings allows me to increase our price point. I provide it as a managed device to many of our clients. I take on the initial costs and charge them a monthly fee. They have threat detection.
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

"On a scale of one to ten, I rate this solution 10 out of 10."
"It's safe and secures my network and applications in some sites."
"FortiGate's web and URL filtering are unlike any other firewall I've used. The functionality of URL filtering in those solutions is problematic because everything is encrypted, and firewalls can't break that encryption protocol. Fortinet has an SSL proxy, so the encryption is done before the packet ever leaves the FortiGate. The URL filter is definitely one of the most helpful features."
"It is easy to install. There is not much complexity involved."
"The notable features that I have found most valuable are that it includes the antivirus, and also IPS, and even SD-WAN."
"Fortinet FortiGate offers several valuable features, particularly as an interface-based solution. Its design makes it easy to understand both incoming and outgoing network traffic through its interface."
"The enterprise-level support is excellent, and we receive quick assistance from Fortinet FortiGate."
"It offers web filtering capabilities at a more affordable price compared to other solutions like PSMs or NETGEAR."
"The product is easy to implement."
"The initial setup is very easy."
"It is not attached to an appliance, meaning if you get a good PC/server, then you can already run a firewall."
"Web filtering is very reliable."
"Web Filter is effective, Web Cache offers bandwidth savings, and the VPN setup is easy."
"The product’s most valuable features are endpoint protection management, load balancing, and connectivity with Active Directory."
"The features I have found the most useful are the web filter, the captive portal, the SSL inspector, and the ad-blocker. They're awesome."
"The solution's most valuable feature is the content filtering."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
"This is a capable appliance and the standard features work well for us."
 

Cons

"They have not yet extended to the cloud."
"The updates Fortinet provides are sometimes unstable."
"Security level could be increased."
"One area for improvement involves FortiAnalyzer, specifically regarding the SOC part and log interpretation. Sometimes interpretation is very difficult."
"They sometimes hide some features and if you want to enable them, you have to go in the CLI, enable the feature and configure it through the CLI. Customers, typically, like everything to be done by the GUI."
"The pricing could always be better."
"The security of Fortinet FortiGate could improve."
"The graphical user interface of Fortinet's FortiGate product does not function well with text-based interfaces."
"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."
"It would be much easier if there was a mobile app."
"The user interface, training, and general product innovation need improvement. Enhancements could also be made to their reporting and accessibility."
"On their low-end appliance, they could have more memory and the largest storage space. The low-end appliance comes with a too-small hard drive, and it could use a little extra room. It only comes with about 4 gigs or 8 gigs of memory, and the hardware space is only 40 gigs, which is really small."
"The storage is minimal, so we have to set the system to delete data after seven days."
"Web-filtering policies could be improved."
"Whenever there are a large number of endpoint VPN clients, connectivity becomes slow."
"For the web filter, I think they can do better especially on the free model."
"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 product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"The product is expensive compared to one of its competitors."
"The price is okay."
"We pay for the solution annually."
"FortiGate Next Generation Firewall costs our company around $12000 per year."
"I rate the product's pricing a seven out of ten. The additional cost depends on the extra feature requirements."
"It is a good product from a price perspective versus functionality."
"The licensing costs are very low."
"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."
"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."
"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."
"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. It is cheaper than Fortinet."
"For the home use, it's cheap."
"The setup cost is about $2000 to $3000 per year."
"The solution is fairly priced."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
