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…

"FortiGate is on the cheaper end, and it offers good value."

More Fortinet FortiGate pros

"In terms of administration, it's perfect."

"The most valuable features of Fortinet FortiGate are the web filters, as we are using them mostly; our content is condition-based, so we are accessing the websites by using the web filters."

"The ROI is good since I get free support."

"Its performance is adequate. We are quite satisfied with its performance. The fact that it is a complete ecosystem with all kinds of integrations is valuable. It did take us a couple of months to get a grip on the new software, but all in all, it replaced our on-premise and single-point solution environment."

"While the stability maybe isn't quite to the level of Cisco, it is a very cost-effective solution. It's cheap compared to Cisco."

"The product can scale."

"The ease of deployment and management is commendable."

"The stability of the solution is good. We haven't faced any issues at all while using the product."

More Fortinet FortiGate-VM pros

"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."

"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."

Cons

"The interface and product support could use improvement."

"With FortiGate, the main complaint that I have heard is about the technical support."

"The license renewal process, annual renewal price, and the web application firewall features should be improved."

"We would like to see better pricing."

"The pricing of the solution should be more affordable"

"Though the tool's GUI is user-friendly, it can be considered as an area with certain shortcomings where improvements are required."

"We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable."

"Fortinet needs more memory to save the log files. We need it to save the logs on the hardware and not in the cloud. I know this feature is available in FortiCloud, but if we need this log locally, it is not available."

More Fortinet FortiGate cons

"In the next release, I would like to see integration capability with SIEM tools, such as QRadar, and LogRhythm."

"Integrating multi-factor authentication with FortiGate-VM can be challenging. While multi-factor authentication is important, not all customers have it enabled. Integration with third-party solutions like ManageEngine or Duo can be complex and sometimes problematic during testing."

"The tech support calls were not the best and could be improved. There have been times when we felt as if we knew more about the device than the support person on the phone."

"The product does not have a good graphical interface."

"There should be a bit more automation."

"Now they do have the ability to pop up a command line, which is nice, however, the fact that you can't do everything within the GUI is probably a problem."

"We encountered scalability issues in IPSec Module. The tunnels freeze sometimes."

"Interoperability could be improved. The API needs better integration to match accounts and objects more effectively."

More Fortinet FortiGate-VM cons

"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."

"Although manageable, the user interface is a little bit slow and could be improved."

Pricing and Cost Advice

"It is not expensive as compared to Cisco."

"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 think price-wise, the solution is totally reasonable since it has many products to serve, starting from small homes to massive scale sites."

"Other firewalls are more expensive than Fortinet FortiGate, such as the Azure firewall."

"It has a competitive price."

"It's very affordable."

"I give the pricing a nine out of ten."

"If the customer is looking for SD-WAN, it comes free with FortiGate."

More Fortinet FortiGate pricing and cost advice

"The basic pricing in Austria is OK, but asking for special offers, e.g., NPOs, NGOs, trade up, and/or trade in, is always useful."

"I would rate the product's pricing as four out of five."

"It's not a cheap solution but it comes with its benefits."

"The best part of Fortinet is the license is bundled together, so it is easy to use and apply."

"The tool is neither expensive nor cheap, so it is okay."

"We pay for a yearly license."

"It is an expensive solution if you are migrating from an open source solution."

"This solution is very expensive."
