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

"The product is very stable, easy to troubleshoot, and configure, so it has reduced the time it takes for support."
"There are lots of features and most of them are deployed for internet security. Users are protected if they accidentally go to some malicious sites."
"The user interface (UI) is very, very good."
"The most valuable feature is the ease of configuration."
"Fortinet FortiGate brings numerous benefits to my company."
"This solution made it very easy to manage our bandwidth."
"The best feature of Fortinet FortiGate is SD-WAN; it ensures continuous connectivity by taking over during link failures, preventing any downtime for the company."
"The email protection and VPN features are the most valuable."
"This solution is user-friendly."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The DNS-level filtering is impressive for thwarting time scanners."
"The most valuable features of OPNsense are the GUI and frequent updates."
"The solution is good for a basic firewall for a small business or for home use."
"The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used."
"It's more secure and more reliable."
"OPNsense is highly stable."
"The system in general is quite flexible."
 

Cons

"Not all features are available in the web UI. Features such as enabling multiple MPLS circuits can only be accomplished through the command line, so these need to be made available in the web UI."
"The support is the main thing that needs to be improved."
"Currently, FortiGate is providing SSL VPN. But they're missing some features that are available in Palo Alto's SSL VPN."
"FortiGate can improve its token system, as it requires a purchase before use."
"To the best of my knowledge, Fortinet does not have a CASB solution and Fortinet does not have a Zero trust solution."
"The documentation available for Fortinet FortiGate should be improved"
"At the moment, if you don't integrate any third-party solution with a simple Fortinet FortiGate box, the box would not function as expected for superb protection."
"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."
"I haven't seen any feature that will allow me direct authentication for a VPN solution."
"The interface needs to be simplified. It is not user-friendly."
"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."
"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"There are issues with stability and reliability."
"The reporting part could be better."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"When using the solution at the beginning was difficult. There was a steep learning curve."
 

Pricing and Cost Advice

"Some of our customers are using Sophos and SonicWall due to price concerns, as they can't manage the pricing of Fortinet FortiGate."
"My experience with the pricing, setup cost, and licensing for Fortinet FortiGate is quite good. I don't have a public site, such as in Azure, where I can see the pricing. I always have to go through the distributor, and that could take some time to get the real price for each appliance."
"The price range is quite acceptable and normal."
"The license is yearly. We pay for the top end. It's called 360."
"Fortinet is the least expensive solution."
"I would rate the pricing a five out of ten"
"The price is really low. It's cheap in comparison to the cost of Cisco or CheckPoint, for example."
"The price of Fortinet FortiGate is the lowest in the market."
Information not available
"It is open source and free."
"I would rate the pricing three out of ten."
"It costs about $1000."
"There are no licensing costs for OPNsence."
"OPNsense is open source software so at this time it is free for us to use."
"It's not expensive."
"It is a free solution, and when you compare it to alternatives like FortiGate, which is quite powerful but also costly, the value becomes evident."
"The solution is not expensive."
