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.

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.

The intrusion detection system helps our organization by automatically detecting and responding to potential threats
The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page. The intrusion detection system helps our organization by automatically detecting and responding to potential threats. It operates similarly to Darktrace, which detects and responds automatically based on the security rules you apply. Initially, you configure everything to block, and then you can whitelist specific items as needed.

Quotes from Members

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

Pros

"The price-to-performance ratio for using Fortinet FortiGate is always better compared to any other competitor, so they are rated better than the likes of Check Point or Palo Alto."
"It's user-friendly and easy to operate."
"What's most important is the ease of use."
"It's a good product that significantly enhances security and protects organizational data."
"I like how we can achieve total integration."
"Centralized monitoring, policy management, and virtualized appliances allow us to take control over our public and private infrastructure."
"What I like the most is the configuration and that it's simple, and straightforward to maintain."
"The most valuable feature of Fortinet FortiGate is load balancing. It can provide central management and VPNA. Additionally, it has enhanced our security environment."
"The solution is user-friendly and easy to configure."
"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 has an open license. It works very well, and there is an update every month."
"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."
"We can open a new VPN connection easily. It's much easier than with Fortinet in our experience."
"OPNsense is easy to scale when running on the hardware."
"The solution has high availability."
"It is a very good solution. I like the dashboard. I can see what is going on and manage it as I like it."
"The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page."
"Ease of use is the best feature of the product."
"The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page. The intrusion detection system helps our organization by automatically detecting and responding to potential threats. It operates similarly to Darktrace, which detects and responds automatically based on the security rules you apply. Initially, you configure everything to block, and then you can whitelist specific items as needed."
"It's an easy, straightforward management platform to use."
"The most valuable features are the IPS, the firewall function, and the price."
"This solution is quick and easy to configure."
"Easily manageable in a variety of environments."
"Our organization's main concern is stability, and this is a stable solution."
 

Cons

"They could improve the response time and quality of support."
"I wish that they could integrate zero-trust technology into Fortinet FortiGate. I am not sure whether it has been done already, but if they could implement that, it would help significantly."
"The biggest "gotcha" is that if the client purchases what they call the UTM shared bundle, which has unified threat management on both, it's not as easy to manage if you have more than one firewall."
"Lacks training for new features."
"The central management for the FortiGate Fortinet Firewall needs improvement. They have the manager to do the essential management for both SD-WAN and for the security policy. They should also improve the SD-WAN function."
"From a reporting perspective, there's room for improvement. They're providing FortiAnalyzer through which one can get some enhancements, but the visibility and reporting still need slight improvement."
"The visibility of the network can be better. The GUI can be improved for better visibility of the network flow. Other solutions have better GUI in terms of network visibility."
"I cannot say definitively about the return on investment with Fortinet FortiGate because I have always been in the technical field, but most of our clients are very happy since threats were stopped, generating confidence in the Fortinet brand among our clients."
"There are issues with stability and reliability."
"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."
"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."
"The ability to set the VPN IP address would be a welcome addition."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"They should improve IPEs for security in the future."
"An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"A more user-friendly interface would be helpful."
"The product must improve its pricing."
"Stormshield Network Security is quite expensive."
"Improvement is needed in terms of the technical support of the manufacturer."
"Not all the fields are activated yet and we were informed that it will take at least one month."
"The SD card could be more secure."
"This is not a next-generation firewall."
"The filtering configuration could be better. We have some difficulties with the filtering configuration and the filter extension. It's not that easy. It's not that straightforward. In the next release, I would like to see a reporting system. Stormshield doesn't have any tutorials on how to do the configuration and things like that. They just have documentation on the website. If you want to configure, for example, Cisco or Fortinet, you can find tutorials on YouTube. They show you how to configure the features, and so on. In Stormshield, there is nothing on social media or the internet on how to configure different things. The lack of documentation or the lack of material makes it difficult for others to adopt this solution."
 

Pricing and Cost Advice

"Fortinet FortiGate as a less expensive solution than Palo Alto."
"I find it quite reasonable."
"Fortinet Secure SD-WAN delivered the lowest total cost of ownership (TCO) per Mbps among all other vendors."
"The license for Fortinet FortiGate is affordable in my country."
"I would rate the pricing a five out of ten"
"It is very cost-effective. You get features similar to other firewalls, such as Palo Alto, but at a lower price."
"For our organization, the licensing costs are approximately $7,000 per year."
"​We saved a bundle by not needing all the past appliances from an NGFW.​"
"As an appliance, it's in the medium price range."
"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."
"It is free."
"It is open source and free."
"We are not paying any licensing fees. OPNsense is completely free for us."
"The solution is not expensive."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"OPNsense is open source software so at this time it is free for us to use."
"I think the price is good."
"For mid-sized companies, they sell their appliances for good prices."
"We bought a three-year license, and we renew it whenever it expires. The price could be better. It's always very expensive."
"The pricing could be better."
"The SN200 series costs between $500 USD and $600 USD per year, whereas the SN700 series costs approximately $1,000 annually."
"We chose Stormshield for its price, as the Azure firewall was too expensive."
"The price of this solution and the price of support are ok."
