Vasu Gala - PeerSpot reviewer
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

"It is very flexible to use."
"The most valuable feature is the SSL VPN, as it allows us to connect and it separates this product from other firewalls."
"Good anti-malware and web filtering features."
"Whenever we raise a complaint with FortiGate, their response and resolution times are minimal."
"Fortinet FortiGate is a very light product. It's easy to understand."
"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 solution can scale well."
"It's easy to manage. The GUI is very simple, and what is very good is that every product, regardless of size, has the same interface."
"This solution is user-friendly."
"It has firewall and VPN capabilities, which are very valuable features."
"The graphic user interface is very good and it is user-friendly which makes the product easy-to-use."
"The solution is good for a basic firewall for a small business or for home use."
"OPNsense is highly stable."
"Overall, I would rate OPNsense as nine out of ten."
"It has an open license. It works very well, and there is an update every month."
"The initial implementation process is simple."
"We have been operating here in our lab for several months, and everything appears to be extremely stable."
 

Cons

"The cloud features and integration could be improved."
"Maybe they could make some features more accessible, such as a way to translate directions between two networks that share the same subnets."
"Fortinet FortiGate could improve by having more storage in the hardware for log data."
"In the next release, I would like to see the interface simplified to be more user-friendly."
"The command line is complicated, and the interface could be better."
"Fortinet FortiGate can improve by integrating the web application firewall and the DDoS protection part of the solution. Having a WAF feature, web application firewall, and proxy together would be a good benefit."
"I would like some automated custom reporting."
"We would like to see a better training platform implemented."
"I haven't seen any feature that will allow me direct authentication for a VPN solution."
"OPNsense struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."
"There are issues with stability and reliability."
"The ability to set the VPN IP address would be a welcome addition."
"The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform."
"The IPS solution could be more reliable."
"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."
 

Pricing and Cost Advice

"The price of Fortinet FortiGate could improve, it is expensive."
"At the time we bought them, I was satisfied with their pricing; I don't know how the new pricing will be."
"It is not a very costly product if you compare it with other products. The return on investment is also good. If you compare the return of investment and money that you are spending on this product with Palo Alto, Cisco, Check Point, and other solutions, the investment is very less. We are happy with this solution. The optional licenses are there, and you can choose which one you want and which one to avoid."
"Fortinet has more device options that are affordable for small businesses than Palo Alto, and its enterprise-level models are also cheaper. Palo Alto also has a separate license for VPN connections and SD-WAN, but FortiGate offers these features standard."
"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."
"There is no challenge in Fortinet FortiGate pricing."
"Their licensing costs are annual. The UTM feature license along with their support is called FortiCare. We include that as a part of the annual maintenance cost. Palo Alto or Juniper also have an annual subscription charge for UTM. Price, of course, can always be more competitive, but it is not the most expensive product. The price-performance ratio is quite high for FortiGate."
"The price could be lower."
Information not available
"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."
"It's a free solution."
"OPNsense is an open-source solution and it is free to use."
"OPNsense is open source software so at this time it is free for us to use."
"It is free."
"It's not expensive."
"There are no licensing costs for OPNsence."
"It is open source and free."
