Featured Reviews

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.
AnvarSadique - PeerSpot reviewer
Easy setup and effective traffic routing enhance security
In terms of improvements, I think the price could be a concern as Azure ( /products/microsoft-azure-reviews ) services are often more expensive compared to other firewalls. However, the functional aspects of Azure Firewall met our needs. While I found the interface not particularly user-friendly, this is a common issue across vendors.
Akram Zaki Hussein - PeerSpot reviewer
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

"What's most important is the ease of use."
"Valuable features include the Web Application Firewall, and it even has DLP (data leak prevention)."
"The user interface (UI) is very, very good."
"Fortinet FortiGate provides superior protection compared to other firewalls, with high processing capabilities."
"Fortinet FortiGate is easy to use. Anyone can easily maintain it."
"Fortinet FortiGate's ease of management is the most valuable feature."
"Its user interface is good, and it is always working fine."
"The most valuable feature is the interface, which is very user friendly. We are utilizing most of the features, like content filtering. The firewall is powerful."
"There is not a single feature or single product that can ensure security."
"I like its order management feature. It doesn't have the kind of threat intelligence that Palo Alto has, but the order management makes it much simpler to know the difference."
"One of the notable advantages of Azure Firewall is its user-friendly interface, which closely resembles or shares similarities with other Azure components."
"The solution can autoscale."
"The Layer four features are okay and meet my business needs."
"The solution is stable."
"It provided ease of maintenance. If a new firewall was needed, we only had to run the pipelines for this. So, the maintenance was very easy."
"I can easily configure it."
"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."
"We have been operating here in our lab for several months, and everything appears to be extremely stable."
"It has firewall and VPN capabilities, which are very valuable features."
"The system in general is quite flexible."
"It has an open license. It works very well, and there is an update every month."
"OPNsense is easy to use and open source."
"Overall, I would rate OPNsense as nine out of ten."
"The solution is user-friendly and easy to configure."
 

Cons

"There can be more security in hybrid implementations. When a customer has a hybrid environment where some parts are in the cloud, we need a consistent security solution for such scenarios."
"Improvement is needed in the Web Filter quotas to restrict users with allocated quotas."
"We have never encountered any issues with it. The price and deployment part of Fortinet FortiGate is good, but it can always be better."
"They could improve the response time and quality of support."
"It would be good if they had fewer updates."
"Its price could be better."
"Fortinet FortiGate could improve by adding enhancements to FortiMail, FortiSOAR, and FortiDeceptor."
"They have recently acquired a CNAP solution which should be integrated into FortiGate boxes natively for protection at any application layer. Since Fortinet FortiGate has Layer 7 protection, they should integrate that as soon as they can for threat detection and network detection."
"An Azure firewall is not a real firewall."
"The solution should incorporate features similar to competitors like split tunneling."
"Diagnosing blocked traffic was initially challenging because we didn't know how to diagnose and integrate Azure Firewall with other Azure services for storing logs in Log Analytics."
"There is a lot of room for improvement, so I would rate it a six out of ten overall."
"The interface could be improved, it's not very user friendly."
"It's a little heavy compared to a FortiGate or other firewalls."
"In my experience, Azure Firewall is quite expensive, with a high cost. I would rate its pricing a two out of ten."
"It would be much easier if the on-premises, firewall rules, had some kind of export-import possibility in place, which is not the case right now."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."
"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."
"The interface needs to be simplified. It is not user-friendly."
"The solution would not be suitable for anything large-scale."
"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 struggles to handle large volumes of voice traffic, indicating scalability issues in that specific use case."
"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."
 

Pricing and Cost Advice

"The pricing is very reasonable."
"The pricing of the solution is very competitive."
"Other firewalls are more expensive than Fortinet FortiGate, such as the Azure firewall."
"I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable."
"Fortinet bundles FortiGate with other products and because of this, the price is a little expensive to some SMB enterprises."
"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."
"The price range is quite acceptable and normal."
"It is more expensive than Sophos. Fortinet is overall more expensive than Sophos. The small range of Fortinet, such as 60F and 80F, is more expensive than the small range of Sophos. Sophos is cheaper. In addition, if you jump from 80F Series to 100F Series, the price doubles."
"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."
"I rate the product pricing a five out of ten."
"The licensing module is good."
"It is pay-as-you-go. So, you pay based on the usage. If I remember it well, there is a basic fee, and there is a traffic fee. It is not per month. It is per hour or something like that. It is not so expensive."
"The solution is cheaper than other brands. My company has an enterprise contract and we finally got a good price with Azure."
"It is expensive, especially with the premium functions. For one of the clients, it was very expensive. You have to use it more at an enterprise level, and there, it was not at an enterprise level. So, it was very costly, but security-wise, it was a very wise decision to use it that way."
"Azure Firewalls operate on a pay-as-you-go model, similar to cloud services."
"Azure Firewall comes with Azure native services. We did not buy any kind of license for it. Whether you have a free subscription or a pay-as-you-go model, you can deploy the Azure Firewall service... The amount that you use will determine how much you pay."
"It is free."
"The price of OPNsense is good."
"There are no licensing costs for OPNsence."
"The solution is not expensive."
"OPNsense is an open-source solution and it is free to use."
"It costs about $1000."
"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
