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 web filtering facility and application control are the most valuable features from the point of view of our clients. The VPN feature is also quite popular amongst our clients. Two-factor authentication is one of the good features in Fortinet. These features are important for the current scenario of security. Security has become a necessity nowadays. With cyber-attacks becoming more common, protecting an organization's data is one of the major tasks. It is also very stable and scalable, and it is very straightforward to configure. Their technical support is also good."
"Fortinet FortiGate has SD-WAN, FortiView, antivirus, sandbox, and IPS, which are generally well-known features."
"The reporting you receive out of this appliance is excellent. You will not need an external management system."
"We can detect any attack of viruses or malware at the first point of contact."
"We have found it to be very reliable and that's why our teams and various users in our company use it as our main firewall every day."
"Centralized monitoring, policy management, and virtualized appliances allow us to take control over our public and private infrastructure."
"The GUI is good."
"The Intrusion Prevention System and the web filtering are both working well."
"It is easy for me to protect certain ports or even the IP addresses, as well as do whitelisting, blacklisting, and the FQDN when we want virtual machines connected and to protect certain websites."
"The Layer four features are okay and meet my business needs."
"The SIEM that Azure Firewall provides us is very robust."
"In terms of the reporting, it's beautiful. It integrates with Azure monitoring and with Azure policies. That piece is a big help. You can set governing policies and you can use the application firewall, as well as the Azure Firewall, to enforce those policies."
"Azure's cost-effectiveness is its major advantage."
"The most valuable feature is the integration into the overall cloud platform."
"The solution is very stable. When comparing it to other environments, it's actually quite impressive."
"Azure Firewall integrates well with multiple platforms."
"OPNsense is very stable, easy to upgrade, and maintain."
"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."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"It has firewall and VPN capabilities, which are very valuable features."
"I mostly rely on the solution's network intrusion detection and prevention system, along with other systems, CMs, and log management."
"The initial implementation process is simple."
"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 most valuable features in OPNsense are reporting and visibility."
 

Cons

"I think that the infrastructure for the VPN could be improved. The way that it is bundled also made it difficult to use and sell as it is too expensive."
"The web-cache feature which was previously on the FortiGate device, but was deleted with the recent upgrade should be returned. It was a very valuable feature for us."
"I think there could be more QoS features"
"Areas of improvement for Fortinet FortiGate include the need for more training and certification, especially when dealing with distributors globally, which presents challenges in product availability and delivery timelines."
"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."
"Its price could be better."
"There are just some services that aren't available. For example, the Ethernet or point-to-point protocols. They could add these services to their product offering - especially services for ISPs."
"Sometimes you do need to know some CLI commands, so it's a bit harder for technicians or new people that don't know it."
"The development area and QA area could be improved. With those improvements, we can improve projects and take even less time to implement them."
"Azure Firewall is an expensive solution. On a scale from one to ten, where one is not affordable, I would rate the price as a three."
"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."
"It is a cloud service, but the lending speed for each region is not always the same. For example, in China, the speed is slow. They need to think about how to make sure that the service pace or speed is always the same in all regions. It would be a great improvement if they can provide the same pace worldwide."
"They can improve the pricing of Azure Firewall."
"The interface could be improved, it's not very user friendly."
"The solution lacks artificial intelligence and machine learning. It might be in the roadmap. However, currently, it's not available."
"An Azure firewall is not a real firewall."
"I would like to see better SD-WAN performance."
"OPNsense could improve by making the configuration more web-based rather than shell or command-line-based."
"The IPS solution could be more reliable."
"pfSense has better performance and quicker updates."
"The reporting part could be better."
"The user interface could be improved, and the DNS section should be more intuitive."
"Its interface should be a little bit better."
"The interface needs to be simplified. It is not user-friendly."
 

Pricing and Cost Advice

"The price of Fortinet FortiGate is the lowest in the market."
"The price range is quite acceptable and normal."
"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."
"For medium and enterprise organizations, FortiGate is more affordable."
"The Indian market is different than the European and American markets. When you compare they need to be a bit more aggressive on pricing."
"The license is yearly. We pay for the top end. It's called 360."
"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"The license of Fortinet FortiGate should be reduced."
"Azure Firewall is quite an expensive product."
"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."
"The licensing module is good."
"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."
"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."
"I rate the product pricing a five out of ten."
"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."
"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."
"I would rate the pricing a nine out of ten, especially considering the availability of a free community edition."
"OPNsense is open source software so at this time it is free for us to use."
"It is open source and free."
"The price of OPNsense is good."
"I would rate the pricing three out of ten."
"There are no licensing costs for OPNsence."
