Efficient, user-friendly, and affordable
In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

Good interface and firewall capabilities and overall easy to use
The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.

Serves as the main firewall for customers' premises and data centers
The initial setup is straightforward. You can deploy it on-premises or using the cloud. If you configure the device to connect to the cloud, you can deploy the Firebox based on templates. You can add a template for a specific client and deploy it for a particular use case. For example, if you're setting it up for a restaurant or a cafe, you can have templates tailored for those businesses. This significantly reduces deployment time, especially if you have several customers of the same type of business. One person is enough for the solution's deployment, but it will run in less than an hour. A network security engineer meets with clients to gather configuration requirements. He prepares a configuration template before the implementation. When he arrives at the site, he turns on the device, applies the template, tests everything, and then migrates the settings from the existing router or firewall to the Firebox.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"From the firewall perspective, the rules and policies are very sufficient and easy to use."
"In terms of security, we have not experienced any security flaws or loopholes, and it has proven to be quite stable."
"The performance is good."
"The most valuable feature of Fortinet FortiGate is security. They are known for efficiency and are on the top of Gartner Quadrant reviews. Fortinet FortiGate has an easy-to-use platform with a good graphical interface. The configuration is simple and the solution provides an overall good layer of security."
"The most valuable features are SD-WAN, application control, IPS control, and FortiSandbox."
"The stability and scalability of this solution are satisfactory. Its SD-WAN, VPN, and URL filtering features are very useful."
"Whenever we raise a complaint with FortiGate, their response and resolution times are minimal."
"FortiGate's ability to perform as expected and fulfil our needs has been the most compelling feature for network security."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"It's more secure and more reliable."
"The most valuable features of OPNsense are the GUI and frequent updates."
"The solution is user-friendly and easy to configure."
"What I like best about OPNsense is that, as a firewall, it's pretty good. I'm quite impressed with it. I had an excellent experience with OPNsense, which helped me achieve the targets I wanted."
"OPNsense is easy to scale when running on the hardware."
"I find the solution to be user-friendly. It has a lot of reports and easy settings."
"The features that I have found most valuable are the FireWall features. The management side of WatchGuard is quite easy because it supports two ways to manage it - by the web and the other one they call WatchGuard systems manager. I used to be familiar with WSM only, but they improved their GUI in the web browser and now it is much easier to do it within the web browser."
"The Dimension control, the one-spot reporting and control, has been nice. It's been easy to go in and make sure people are doing what they're supposed to be doing and that only the right stuff is getting in."
"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."
"The most valuable feature is the GUI, especially the real-time bandwidth usage report. Also, its integration with WiFi access points is nice."
"The product's usability is good. It is straightforward and simple. One of the benefits is that it is easy to navigate and intuitive."
"We experienced that WatchGuard is easy to setup regarding VPN compared to other firewalls of other brands."
"Firebox operates effectively in the background, blocking potential threats without a need for constant monitoring."
"The throughput is great. It's perfect. We have no issues whatsoever. The management features are very powerful..."
 

Cons

"The customization could be improved. Cisco, for example, is much better at this. They need to work to be at least as good as they are."
"At this moment, we believe that Fortinet FortiGate should be improved by injecting more AI because the kind of threats we are seeing are more ransomware threats. Fortinet FortiGate is able to ensure these threats do not enter, but we would prefer to see more proactive alerting mechanisms come out."
"It would be ideal if they had some sort of GUI interface for troubleshooting and diagnostics."
"One area for improvement is the performance on bandwidth demands for smaller devices, as well as better web filtering."
"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."
"Though the tool's GUI is user-friendly, it can be considered as an area with certain shortcomings where improvements are required."
"The firmware needs improvement because there are bugs when a new release comes through. Sometimes, the configuration changes, and it's a bit harder to see where the fail is. The first time that you have the firmware, it tends to have some issues, and it's better to wait a bit to update the equipment."
"In terms of what could be improved, the SD-WAN is quite difficult, because if you install the new box, 15 is okay, but if you change from an old configuration, if there is already configuration and a policy when you change to SD-WAN, you must change the whole policy that you see in the interface."
"The IPS solution could be more reliable."
"I would like to see better SD-WAN performance."
"You will need additional training before you can actually start to use it."
"The logging could improve in OPNsense."
"The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs."
"They should improve IPEs for security in the future."
"There are issues with stability and reliability."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The documentation for the System Manager/Dimension configuration, could be a little bit clearer... The use case where you have multiple sites with multiple firewalls, and one site that has the System Manager server and the Dimension server, wasn't really well defined. It took me a little bit of digging to get that to actually work."
"There is room for improvement in the threat protection, data packet inspection, and performance of the solution. Generally, it's just a lower-end product. It does the job but doesn't do it very well."
"The scalability of the solution needs improvement."
"One other shortcoming is that there is no backup for it. We really haven't figured out how we might solve that problem. We may want to put a duplicate in... With WatchGuard, we just have the one box. If that were to fail, we'd probably be really hurting."
"I believe there is a need for additional measures to connect mobile devices securely to the Firebox router."
"One area for improvement could be making the interface even more user-friendly."
"It would be wonderful if the WatchGuard team develops nice products for threat intelligence."
"The solution needs to improve its accessibility."
 

Pricing and Cost Advice

"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."
"For the price, I'd rate it a ten because it's very cost-effective."
"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."
"Here in Brazil, we're going through difficult economic times and the tax on the dollar is high. All the solutions from minor competitors are growing in the market. The prices have come more competitive."
"Fortinet FortiGate is expensive."
"The pricing for this solution is good."
"The price of Fortinet FortiGate is reasonable for an SME."
"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."
"It costs about $1000."
"It's not expensive."
"OPNsense is open source software so at this time it is free for us to use."
"I would rate the pricing three out of ten."
"We are not paying any licensing fees. OPNsense is completely free for us."
"The solution is not expensive."
"There are no licensing costs for OPNsence."
"It is free."
"The cheapest configuration, for maybe five people, is approximately $500."
"Their price point worked, which is the reason why we stayed with WatchGuard."
"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."
"Despite the fact that there is always room for improvement, the current pricing of the solution is still lower compared to its competitors."
"It costs me about $800 a year."
"It is an entry-level product, so the price is cheap."
"The cost three years ago was about $800."
"Very competitive pricing regarding throughput compared to other alternatives."
