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.

User-Friendly, improves security, and gives me more control over my VoIP
We purchased the solution and we are partners. I haven't had a chance to go through all of the features and what this solution offers, but I think that it has an integrated VPN. I am looking forward to using another VPN. I am anxious to see it, as we are going to set that up for one of the clients. At this time, I am not able to add any comments on how this solution can be improved, because this solution does what it is asked to do. I would rate this solution an eight out of ten.

Robust network security and management offering a user-friendly interface, open-source flexibility, and cost-effectiveness, with challenges regarding initial setup and the absence of official support
The interface is user-friendly, but there's room for improvement in terms of intuitiveness. The bundle management aspect requires additional attention to make it more intuitive, especially for inspecting high-level traffic. This is crucial, especially for larger companies where the existing features might not be the most optimal choice, given limitations like printer constraints. For high availability, it's crucial to have a method in place where a designated component oversees the entire process. Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine. It would be beneficial if OPNsense supported additional virtualization platforms like Hyper-V from Microsoft and VMware, similar to how Kaspersky has integrated them.

Quotes from Members

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

Pros

"Its user interface is good, and it is always working fine."
"The solution is scalable."
"The features I find most useful in Fortinet FortiGate are its simplicity of utilization, which is very important, and its provision of interfaces to see the alerts and other things."
"It has improved our security capabilities."
"It is easy to manage, and it doesn't need much knowledge from the team. It is a stable device, and there are many features that are included out of the box."
"The payment function for applications is good."
"The reliability of Fortinet FortiGate is through the roof, we're experiencing 99.999% availability consistently."
"The most valuable feature is the ease of use."
"This solution is user-friendly."
"The feature I find most valuable, is that the program helped me to realize all the requested functionality that was needed."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"OPNsense is very stable, easy to upgrade, and maintain."
"The initial setup is easy. It only takes 15-30 minutes to deploy."
"OPNsense is highly stable."
"I find the solution to be user-friendly. It has a lot of reports and easy settings."
"It's open source."
"I feel that its valuable features are that it is simple and free."
 

Cons

"Reporting is limited to providing an external appliance for improving the reporting capabilities of the FortiAnalyzer. It does not offer a central management and is also sold separably as an appliance."
"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."
"Its pricing can be better."
"There is room for improvement related to the logging and reporting aspect."
"Fortinet FortiGate is a stable solution. However, my issue is the performance only. When I use all the profiles, this affects the performance. From the beginning, I should have had a better sizing of the box."
"Improvement is needed in the Web Filter quotas to restrict users with allocated quotas."
"There are a lot of bugs I have found in the solution and it is difficult to upgrade. These areas need improvement."
"Fortinet FortiGate could improve by having more storage in the hardware for log data."
"I haven't seen any feature that will allow me direct authentication for a VPN solution."
"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server."
"The ability to set the VPN IP address would be a welcome addition."
"We did not like the fact that you have to configure everything with the graphic user interface. We have used other firewalls, such as FortiGate, that you can configure via code. OPNsense is not easy to integrate. When you are deploying via GitHub or another source repository, this is not possible. That's one thing we didn't like much."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"There should be more technical documentation."
"The user interface could be improved, and the DNS section should be more intuitive."
"There is room for improvement in SSL inspection."
"The interface of the solution is an area with shortcomings."
 

Pricing and Cost Advice

"The cost is too high... They have to focus on more features with less cost for the customer. If you see the market, where it's going, there are a lot of players offering more features for less cost."
"It is affordable. Palo Alto is much more expensive than Fortinet."
"It's a very full-featured and it's priced well solution."
"There is a license to use Fortinet FortiGate."
"I think that the pricing is fair."
"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."
"The price depends on the size of the company. From the beginning, you just want to know the internet bandwidths, speed, and the number of users to be able to offer the right product and model. They have a lot of products in FortiGate according to the size of the company, like 200D and 300D."
"The license is yearly. We pay for the top end. It's called 360."

"It is open source and free."
"It costs about $1000."
"I've used the free version. My computer with two network cards at home allows me to try as many different software options as I want. I did pay for the license, but it was for the Zenarmor license, which is the packet inspection tool. They use AI for packet inspection, which integrates with OPNsense and pfSense."
"There are no licensing costs for OPNsence."
"The price of OPNsense is good."
"OPNsense is open source software so at this time it is free for us to use."
"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
