Efficient, user-friendly, and affordable
In the past, NSS Labs was utilized to test files and verify the numbers and datasheets. It would be beneficial to have an organization or testing lab that can verify the numbers in our datasheets since changes are frequently made, which can be inconvenient for review. For instance, when comparing different competitors such as Forcepoint, Palo Alto, and Check Point, the throughput or numbers in the datasheet may be lower than the actual numbers. Conversely, Fortinet typically reports very high numbers, but they cannot be replicated in the real world. Therefore, it would be advantageous for them to partner with a neutral testing organization such as NSS Labs to validate these numbers, thus providing more credibility and comfort to everyone regarding the accuracy of the datasheets. For the migration, everyone has a firewall in use and I am selling Fortinet. Typically, I am replacing another firewall. Previously, there was a tool available to convert configurations from one firewall, such as Palo Alto, to Fortinet, but this tool is no longer free. If it could be made free again, it would be very beneficial. This tool shows a lot of promise and is very good. Making it free would help many companies deliver their products in a more efficient and integrated way. It would also be more valuable to include the tool with the firewall package or license instead of having to pay extra for it. Paying extra puts more pressure on small companies to deliver the firewall and complete the configuration, especially if they have hundreds or thousands of policies. It's very painful to move through these policies line by line. The stability has room for improvement. When it comes to Secure SD-WAN, everything is fine. They are going the right way. SD-WAN is very promising. They can provide the SD-WAN solution separately, but they will not take this approach because even the smallest firewall can support the features, so there is no need to have a separate service or appliance. They are following the right steps, and there is nothing to be improved. Feature-wise, I'm really satisfied with the new release, and the features they have added. For now, it's fine.

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.
Eddy Ramirez - PeerSpot reviewer
Good interface and firewall capabilities and overall easy to use
The security has improved as we can isolate the network. We can do attrition prevention via a tool that comes with the solution. We can have a VPN solution in place for those that work from home, outside the network, in a secure manner. We also like that it offers good authentication. It offers radius-based authentication, which has been useful for the company. The main platform is under the Open VPN firewall. The solution has high availability. When we have different ISPs, we can actually load balance those links or actually put some priority or even classify the traffic that might go into one ISP or another.

Quotes from Members

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

Pros

"The email protection and VPN features are the most valuable."
"Fortinet FortiGate is a security device. It can optimize security on the networks of a company. It actually protects the company from attacks from outside. With FortiGate, you can categorize the users. You can create a group of users that can access all of the websites for their work. You can limit other users' access."
"It is a good source for firewall protection."
"FortiGate Secure SD-WAN includes best-of-breed next-generation firewall (NGFW) security, SD-WAN, advanced routing, and WAN optimization capabilities, delivering a security-driven networking WAN edge transformation in a unified offering."
"Advanced routing (RIP, OSPF, BGP, PBR). It gives you a seamless and simple integration into a large network."
"It is user friendly, and has all the features you need."
"The most valuable feature of Fortinet FortiGate is URL filtering."
"It's great for capturing the traffic and troubleshooting it."
"Performance and stability are the key features of this product."
"Among the most valuable features are the DDoS protection that protects your virtual machines, the threat intelligence, and traffic filtering."
"Azure Firewall's feature that I have found most valuable is its scalability."
"The firewall policy control, URL content control, and antivirus are all the most valuable aspects. Threat prevention is as well quite good."
"Azure Firewall integrates well with multiple platforms."
"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."
"Azure's cost-effectiveness is its major advantage."
"Microsoft's technical support is very good. They're quite knowledgable and responsive."
"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."
"The most valuable features of OPNsense are the GUI and frequent updates."
"The solution has high availability."
"It has an open license. It works very well, and there is an update every month."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"We have been operating here in our lab for several months, and everything appears to be extremely stable."
"I feel that its valuable features are that it is simple and free."
"The IDS and IPS features are valuable. From the usability perspective, there is a lot of good documentation. As IT professionals, we found it very easy to configure the firewall. It was easy to configure and use."
 

Cons

"The pricing could be reduced or include the first year warranty."
"Quality control on their firmware versions needs improvement. When they introduce new firmware, there tend to be bugs."
"The configuration part was challenging, especially converting configurations from another OEM to FortiGate."
"The monitor and the visibility, in this proxy, is very weak."
"I would like to see improvements made to the dashboard and UI, as well as to the reporting."
"Its reporting and pricing need improvement."
"The advanced models are expensive."
"They should make the rule sets more understandable for the end user. When you're trying to explain to somebody how a computer network is secured, sometimes it's difficult for an end user or customer to understand. If there was a way to make the terminology more accessible to the end user, the set up could be easier. They should translate the technical jargon to an easily relatable and understandable conversation for the end user, the customer, that would be brilliant. Particularly in an environment where the IT structure is audited regularly, there's always pressure from the auditor to up the standards and up the security and you get your USCERT's that come out and there's a warning about this and the customer will want to lock out so much and when you apply it they run into issue where they can't search the internet or print to their remote office. Of course they can't print to your remote office, they just locked it up. They should make the language more understandable for the customer. If there's a product out there that made the jargon understandable to John Q. Public, I would buy that."
"They can improve the pricing of Azure Firewall."
"The interface could be improved, it's not very user friendly."
"You have to have a defined IP range within your network to associate it with your network. The problem is you have to plan ahead of time if you expect to use the firewall in the future so that you don't have to reconfigure your subnets or that specific IP range. Other than that, I don't any issues. I use it for basic configuration for a single application, so I really don't try to leverage it for multiple applications where I might find some complexity or challenges."
"It needs a lot of improvement, especially on intruder detection. They are working hard on that."
"The threat intelligence aspect of this particular firewall is not at par with other providers."
"Azure has new versions including a premium firewall. But I would like to see them not put the premium features on Azure Firewall Premium alone because it is quite expensive."
"The solution lacks artificial intelligence and machine learning. It might be in the roadmap. However, currently, it's not available."
"For larger enterprises, they need to adjust the scalability."
"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."
"They should improve IPEs for security in the future."
"The interface needs to be simplified. It is not user-friendly."
"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."
"I would like to see better SD-WAN performance."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"The user interface could be improved, and the DNS section should be more intuitive."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
 

Pricing and Cost Advice

"The price of Fortinet FortiGate is reasonable."
"If you purchase a one-year subscription with the hardware and then you want to renew for the second year, it is very costly."
"The price of Fortinet FortiGate is the lowest in the market."
"The price for the device and software is high. However, the solution is of good quality and has a lot of features."
"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."
"The pricing is justified. It's a little pricey, but what you pay for is what you get."
"Fortigate's pricing is competitive."
"While Fortinet FortiGate has a higher price point compared to Sophos XG, its user-friendly interface justifies the cost."
"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."
"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."
"The pricing of Azure Firewall is pay-as-you-go. Fortinet also has a pay-as-you-go model, but Azure's pricing is higher and, with FortiGate, you also have the license."
"Azure Firewall is more expensive. If Microsoft can make Azure Firewall cheaper, I can see that all clients will think of using it. One client used FortiGate because it is much cheaper. Some clients ask me for Cisco, but in the cloud estimate, I found its cost is the same as Azure Firewall."
"Azure Firewall is quite an expensive product."
"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."
"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."
"It costs about $1000."
"OPNsense is a well known open-source tool."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"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."
"The solution is not expensive."
"It is free."
"OPNsense is an open-source solution and it is free to use."
"It is open source and free."
