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

"It is a good source for firewall protection."

"FortiGate is very simple to manage and easy to use."

"The GUI is very simple, and what is very good is that every product, regardless of size, has the same interface."

"I appreciate the ease of use, ease of setup, and the different abilities it has; I have been very pleased with it over SonicWall, the interface of Fortinet FortiGate is a lot easier to use and more robust, plus their VPN option is much better."

"The most valuable feature is the deep inspection for traffic, which is capable of identifying zero-day attacks."

"Provides good VPN capabilities."

"The combined license for the network, the next-generation firewall, and the integration with SD-WAN for all branches are what I consider to be the best features. It's effective for multi-branch customers."

"The solution can scale."

More Fortinet FortiGate pros

"The most valuable feature is geofencing, where we can block all access from all non-domestic locations."

"The solution offers good documentation."

"High network throughput while providing leading edge network security technology for a competitive price."

"It gives all the features of a full-fledged firewall with great performance."

"It is very versatile."

"The tool's most valuable feature is its ability to deploy it on live physical hardware. Specifically, when providing firewall services for clients, we can leverage such hardware appliances to support multiple customers on the same hardware."

"It provides an ease of management and configuration as well."

"The policies are very valuable. They allow me to secure and manage future traffic effectively."

More Fortinet FortiGate-VM pros

"The solution can scale well."

"The Zyxel Unified Security Gateway solution is stable and does its job effectively."

"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

"Some of the features in the graphical user interface do not work, which requires that we used the command-line-interface."

"It should provide better visibility over the network and more information in the form of reports for the end users. Its installation should also be easier."

"Fortinet technical support is lacking, as OEM support is slightly better. Improvement in their technical support could include response time as well as having more technically sound people in tech support."

"The visibility of the network can be better. The GUI can be improved for better visibility of the network flow. Other solutions have better GUI in terms of network visibility."

"Maybe they could make some features more accessible, such as a way to translate directions between two networks that share the same subnets."

"Price, of course, can always be more competitive or better."

"There are SD-WAN network monitoring, SD-WAN features, Industrial Databases, Internet of Things, Detection, etc., however, we do have not licenses for those features. We thought that if you bought a product, you should have all of the features it offers. Why should you need to make so many extra purchases to enable features? They should have one price for the entire offering."

"Fortinet FortiGate SWG's costs need improvement."

More Fortinet FortiGate cons

"The users must buy FortiSIEM to get advanced analytics."

"We are experiencing a failed login issue. There should also be improvements in functionalities we store to enhance our services."

"The product is satisfactory. I haven't identified any features to improve, and based on the number of deployments I've handled with FortiGate-VM, there haven't been any complaints from the customer's side."

"Integration could be better. Whatever devices I'm using with FortiGate are all compatible. The access points and switches are also FortiGate, so I can easily integrate them. But it would be better if we could embed other devices as well. There are compatibility issues with other brands, and we need that. We can only integrate universal brands with FortiGate. The initial setup could also be easier."

"There is always room for improvement in any solutions, including Fortinet's FortiGate-VM. Although the solution claims to have a superior throughput compared to other OEMs, upon closer examination and comparison, there is potential for significant improvement in this area. In today's rapidly evolving technology world, it is important to continuously strive for enhancement and development, and I believe Fortinet can make significant strides in this direction for the FortiGate-VM."

"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 stability could be improved. I find Cisco to be more stable than Fortigate, which is I major differentiator between the two."

"Licensing could be easier to understand."

More Fortinet FortiGate-VM cons

"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

"It is not the cheapest one, but its price is very competitive."

"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."

"It's an expensive solution."

"The licensing costs are very low."

"The price is okay."

"There is a subscription-based model to use Fortinet FortiGate. We pay annually for the solution along with the support. If you want to have all the updates, and security patches you will need to renew your support."

"It's an expensive solution"

"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."

More Fortinet FortiGate pricing and cost advice

"I rate the product price a seven on a scale of one to ten, where one is a low price, and ten is a high price."

"I rate Fortinet FortiGate-VM's pricing a six out of ten."

"The price: It is a bit higher than the other competitors. This is why I started to look at other brands."

"There is an annual license required to use the solution."

"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."

"The license can be purchased at intervals of one, three, and five years."

"At present, the SD-WAN licenses are on an annual basis."

"For large enterprises, price is not a problem because they need that solution. However, in the Philippine market, many of our clients are still small to medium businesses, so the price can be challenging. The license for Fortinet FortiGate-VM costs 100K to 150K Philippine pesos per year for VM1 or VM2."

More Fortinet FortiGate-VM pricing and cost advice

"This gateway is pretty cheap."

"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
