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.

Faced hardware limitations and setup challenges but have improved network protection over time
I spent much time finding exact firmware on Aruba which was working with these guns, but it is not optimal because it is not the latest version, so there could be potential security problems. We decided to replace those access points with another one. I personally have trouble because I don't know the exact life cycle of Fortinet FortiGate-VM boxes. I don't know if the life of boxes is five years or something else; we moved from our previous company, which sold us to other companies. Before 10 years, we had a special department that took care of core networks, including firewalls. After that, this responsibility fell to me and my colleague. It is not easy to set up these Fortinet FortiGate-VM boxes properly because we didn't have previous experience with this kind of solution. At first, we set up only a few rules that were not secure enough, and over a couple of years, we improved the settings and security of these Fortinet FortiGate-VM boxes. Currently, I have one Fortinet FortiGate-VM that needs to be replaced next year, and this box is not so powerful, so I need to redirect some traffic to another Fortinet FortiGate-VM. It is stable, but because the CPU processor of this box is not powerful, I need to redirect some traffic to another box. In the future, I need to choose a higher-level box to prevent potential troubles with the power of this box.

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

"The main reason why I purchased the particular unit was that it had good reviews and what other people were saying as far as its completeness and its leading capabilities in terms of endpoint security was very good."
"We can detect any attack of viruses or malware at the first point of contact."
"Regionally, we are well covered. Technical support is good in this area."
"I have found the IPS, antivirus, and the feature that allows you to have a firewall in the same appliance most valuable."
"We like signature-based anomaly detection and zero-day protection features."
"FortiGate is a rapidly growing vendor with a wide range of ready-to-use products. Their delivery time is remarkably quick, usually between two to four weeks."
"FortiGate NGF is simple compared to other firewalls. It is easy to use and you don't need any training. Any person with basic firewall knowledge can use it."
"The most valuable features of Fortinet FortiGate SWG are IPS and scanning."
"The features and capabilities of Fortinet FortiGate-VM that I have found most valuable are not only specific to Fortinet FortiGate-VM, but generally for most sites: a valuable web filter and DNS filter work together."
"The EPM bundle is a good feature."
"The solution is very easy to set up. It doesn't take a lot of time and offers a quick deployment, so you can start using it almost right away."
"The user interface is the most valuable aspect of the solution."
"We switched to FortiGate because it's straightforward and easy to manage and also has co-costing for customers."
"Fortinet FortiGate has positively impacted our organization by allowing us to scale fast."
"The most valuable FortiGate-VM features are the ease of use and setup."
"Fortinet is competitively priced, it's cheaper than Palo Alto and Check Point."
"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."
"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 cost is very low."
 

Cons

"The product does need better support in the cloud environment. It's not exactly cloud-native right now."
"Another issue is how deduplication services don't work reliably after enabling deduplication on Fortinet."
"FortiWAN was supposed to help in doing intersite linking, but we've realized that most of the ISPs use BGP."
"Support could be improved."
"The things we require are already sorted out, so there isn't any scope for improvement as far as our requirements go. However, its price can be better."
"Fortinet FortiGate firewall is good, but other products like the switching part and all that fabric, in handling very audio-video traffic, sometimes it struggles on the switching part, but on the routing part, it is fine."
"Their software support needs improvement. I would prefer to have better support for bug fixes. Sometimes, we open a ticket, and it is very difficult to get a solution. Specifically, we are not at all happy with their support for load balancing."
"The ease of use could be improved."
"Web filtering is a feature that needs some improvement. There should be some additional features to allow active users to change their own passwords."
"Pricing is complex."
"FortiGate's application load balancing has to be improved. They need to improve a lot on the load balancing and RAF side. They are far behind Citrix in that regard."
"The block, the clarity, the quarantine command, is not very user-friendly. You would have to do everything through the command line and I would have preferred if it wasn't a CLI."
"The price and licensing of the solution can be better."
"In terms of room for improvement, logging could be improved."
"FortiGate is a nice and very good product but the implementation and post-implementation of the product are cumbersome."
"To improve FortiGate-VM, Fortinet needs to harden it more."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"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 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."
"Sometimes it reboots when you least expect it, and that's the main issue."
 

Pricing and Cost Advice

"The price is relatively expensive compared to other solutions which are providing similar features."
"They are more expensive than others."
"If the price of the license in Fortinet FortiGate was less expensive it would be better."
"It has a competitive price."
"Its pricing is competitive with other solutions."
"The licensing costs are very competitive."
"The price of Fortinet FortiGate when compared to other solutions is high. However, my knowledge of the price is from third parties and I am not sure how accurate it is. I typically work in the technical area of my organization."
"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."
"The price of the solution is competitive. Fortinet FortiGate-VM had a lot of advantages when it came to pricing. However, the competition has also geared up to a larger extent and it has become comparable now to the other solutions."
"​It is on par with what you receive. It can be expensive upfront."
"I would rate the product's pricing as four out of five."
"It's a mid-ranged product."
"The price is fair for what we get with FortiGate."
"There is a support fee that can be bought on a yearly or two-yearly basis. I don't think they do five years. The best benefit is that the same pricing is guaranteed for that duration. If you can afford it, I would recommend using the longest possible time span."
"There is a need to make payments towards the licensing costs attached to the solution."
"The price of this product is great compared to others."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
