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.

Makes defining policies simpler but lacks performance and modern features

WatchGuard Firebox is only deployed in one location within my customer's organization, and at the other locations, we are using Meraki and FortiGate. We plan to replace WatchGuard Firebox soon. My impression of the spam blocking capabilities of WatchGuard is not very favorable, as I don't think it is very capable. I haven't noticed effective web ratings or IPS signatures, which may be due to managing an older OS; I'm not certain about the performance of the newer versions. I am not aware of whether the transition to faster ports on WatchGuard Firebox supports maintaining productivity levels during peak usage times. Based on my experience, I would rate WatchGuard Firebox as five out of ten overall.

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 most important feature, normally for small business customers, is link load balancing."

"The SD-WAN is the most valuable feature."

"The most valuable features of Fortinet FortiGate are its SD-WAN capabilities, such as dynamic routing, and other features, including security options such as antivirus, IPS, and IDS—all integrated into one device."

"FortiGate firewalls are easy to manage through a user-friendly web interface. They also have advanced features like DDoS and DLP. However, I wouldn't recommend enabling all of these features on one device because it can cause performance issues."

"The feature I like most is the SD-WAN. It allows you to manage more than one ISP at the same time. And there is a high-availability mode, so if one of your ISPs is down, you still have a backup."

"The solution is stable."

"It's very easy to set up, it's very easy to make policies and, for an organization, that means you don't need IT expert in firewalls. You just need to have somebody who knows a little bit of IT, and that's it. With other products, you need someone with a "Masters" degree in firewalls."

"The strengths of Fortinet FortiGate include network security, VPN, site-to-site tunnels, client VPN solutions, two-factor authentication for VPN clients, and SD-WAN for branch level. We have implemented these solutions for various customers."

More Fortinet FortiGate pros

"All of the features have been valuable. There's nothing on my M270 that I'm not using. If you have remote access, you can see how many users are coming from the outside world to be connected to the systems, through the virus systems that we have behind the firewall, in order to gain access to their files and do their work. We can also see how long they stay online and whether these connections are closed forcefully or for any other reasons, such as a glitch or some kind of misbehavior, to see if internet traffic is optimized and if that particular traffic is under company policies, concerning which websites were visited."

"WatchGuard Firebox is the most powerful firewall for Wi-Fi security."

"Management and visibility are the most valuable features."

"What I found most valuable in WatchGuard Firebox is that it's a functional platform that works, and each of its features works well. The solution also has good reporting and dashboard capabilities. I also find the overall performance of WatchGuard Firebox great."

"I find that their tech support is excellent. And as a reseller, my relationship with my point of contact is also strong. WatchGuard does a good job of maintaining that."

"The most valuable feature is the correlation of logs from different devices."

"The GUI is easy and intuitive."

"The most valuable feature of this solution is traffic management."

More WatchGuard Firebox pros

"The solution can scale well."

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

"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."

Cons

"There are some tiny bugs that sometimes affect the operations. In the past revision of it, there was a bug. Because of the bug, we had to downgrade the version. It happened only with the last revision."

"To the best of my knowledge, Fortinet does not have a CASB solution and Fortinet does not have a Zero trust solution."

"One area for improvement is the performance on the bandwidth demands for smaller devices, as well as better web filtering."

"I would like to see improvements in the support from Fortinet. Here in the Philippines, whenever we have problems with a Fortinet product, we mostly ask for support from distributors and resellers and not directly from Fortinet."

"The integration with third-party tools may be something that they should work on."

"This product needs to have an analysis feature, rather than having the analysis done through the integration of a different product."

"Fortinet technical support is lacking, as OEM support is slightly better."

"The AI with Fortinet FortiGate is not very well integrated on their devices, and their cloud infrastructure is not as good as Cisco's."

More Fortinet FortiGate cons

"The solution is a bit confusing and there are unusual complications with setup."

"Websense is an application that monitors and filters internet traffic. Websense was derived from WatchGuard. But when you go to WatchGuard to actually implement that particular feature, you have to use some type of additional feature and you have to pay for it, unfortunately. I think it should be free or free in the WatchGuard box itself, as an option. It would be nice if they didn't charge us for that."

"There is a slight learning curve."

"Last year, I had an issue with one of the Fireboxes going down. It was overheated, because my server room became overheated and this fried it."

"The solution is lacking a professional website, they should be updated more often."

"One area for improvement is the limitation in the product portfolio compared to competitors like Fortinet, which offers a broader portfolio including Authentication, VPNs, FortiMail, Sandbox, and Email Security."

"This solution needs the option to add an external hard drive."

"Once you start getting into proxy actions and setting up: "Okay, cool. Once this rule gets triggered, what actions have to happen?" I do know a few people who use WatchGuard and they still have to get assistance when they look at that. So I would file that as a con for WatchGuard. Proxy actions can be a little bit complicated."

More WatchGuard Firebox cons

"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

"I give the pricing of the solution a six out of ten."

"The solution is offered as an annual license."

"FortiGate Next Generation Firewall is an expensive solution with a yearly subscription."

"It is around $50,000 per month."

"Before choosing a piece of equipment you have to take into account the cost-benefit offered by each one. Sometimes it is not worth paying a very cheap price to have a minimum level of security."

"Fortinet Secure SD-WAN delivered the lowest total cost of ownership (TCO) per Mbps among all other vendors."

"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."

"The tool's pricing is neither cheap nor expensive. Overall, I find it to be competitive in the market."

More Fortinet FortiGate pricing and cost advice

"The cheapest configuration, for maybe five people, is approximately $500."

"We paid $4000 in AUD for WatchGuard Firebox per year. There were no additional costs."

"The licensing can be a one-time purchase unless you need the extra services for example twenty-four seven support."

"They license it. When we buy it, we buy it with a three-year license. That's the most cost-effective way to do it. So, if you're going to buy it, then buy it with the three-year licensing."

"I buy a three-year renewal on the main device, which is usually around $3,000 to $4,000. They usually upgrade the device when I do it. You get a big discount when you do three years."

"We had a trade-in offer at the end of our first three-year term. As a result, we pretty much got a free device by buying the three-year subscription. It was around $3,000 for the three-years."

"They have an annual subscription license. Initially, we had opted for three years. After that, we went for another three years, and after that, we have been doing it yearly. They also have a license for five years."

"Cheap."
