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 FortiGate controls the user's activities and maximizes my bandwidth use overall."
"The SD-WAN function is very developed. It has SD-WAN functionality with security features in one device. We can manage from one single console SD-WAN and the security policy."
"The ability to set up remote systems is the most valuable feature."
"The features that I have found most valuable are the SD-WAN and their IP4 policy."
"Its administrative panel is very intuitive and simple. It is simpler than the other solutions that we had. As an administrator, we are always looking for the easiest solution to manage network policies. We are able to filter everything on our network and also use the VPN feature, which is important these days when people are working remotely during COVID."
"The most valuable feature is the FortiManager for centralized management."
"The solution is easy to configure and maintain remotely."
"The best features of Fortinet FortiGate are that it does the job effectively and protects our environment."
"It's helped us improve our security posture."
"Azure Firewall is a cloud-native solution that removes the pain of load balancers."
"Azure Firewall is integrated well with Microsoft ecosystem."
"We secure the entry point to the virtual data center with the firewall."
"The solution is stable."
"The solution can autoscale."
"The solution should be capable of self-scaling, which is one of the features we like about it."
"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 initial implementation process is simple."
"The most valuable feature is the Dual WAN in OPNSense, which offers advanced capabilities."
"OPNsense is highly stable."
"The solution is good for a basic firewall for a small business or for home use."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
"The most valuable features of OPNsense are the GUI and frequent updates."
"What I like the most about OPNsense is that it offers an easy-to-use dashboard for device management and control."
"The technical support is very good."
 

Cons

"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."
"Fortinet FortiGate can improve the integration with Active Directory. Additionally, I would like to have a Cloud Controller, such as they do in the Cisco Meraki solution."
"The UTM filtering needs improvement."
"Fortinet FortiGate needs to improve the logging and reporting. Additionally, the next-generation application's policies should be improved. When they were released they had bugs."
"In the balance between links feature normally you can just choose one option to balance. It would be better for the solution to have more than one option, preferably three."
"The initial setup and configuration are not intuitive and require training."
"Fortinet needs more memory to save the log files. We need it to save the logs on the hardware and not in the cloud. I know this feature is available in FortiCloud, but if we need this log locally, it is not available."
"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."
"It has fewer features than you can get from other firewalls, like anti-spam and anti-phishing. Those kinds of things are not included. It only includes IDS and IDB."
"The solution should incorporate features similar to competitors like split tunneling."
"An Azure firewall is not a real firewall."
"The reporting, logging, and monitoring features, as well as the flexibility of the policies, need to be improved."
"The product pricing could be more competitive."
"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."
"Azure should be able to work better as a balancer also, instead of just being a firewall. It should have a wider mandate."
"SD-WAN (software-defined wide area network) is integrated into some restricted service providers for OPNSense."
"When using the solution at the beginning was difficult. There was a steep learning curve."
"On the customer-side, because I'm a small business, I need a cheaper or free solution option."
"The support for OPNsense is good because we have documents available on the internet. The support could improve a little."
"While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet."
"The solution would not be suitable for anything large-scale."
"I would like better documentation concerning the provided packages and their integration."
"You will need additional training before you can actually start to use it."
 

Pricing and Cost Advice

"Setup costs and pricing depends on many variables, but it's mostly affordable."
"These boxes are not that expensive compared to what they can do, their functionality, and the reporting you receive. Fortinet licensing is straightforward and less confusing compared to Cisco."
"The initial setup is super straight forward and as far as the licensing goes for the small product that we have, the pricing was pretty competitive. It wasn't as simple and as cheap as a SonicWall but for the service we would get it was a good price."
"It has a competitive price."
"Its licenses cost the same for different subscription plans."
"The pricing for this solution is good."
"We just pay a flat monthly fee to the vendor for the support."
"The pricing of the solution is very competitive."
"Azure Firewalls operate on a pay-as-you-go model, similar to cloud services."
"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."
"Azure Firewall is expensive."
"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."
"Azure Firewall is quite an expensive product."
"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."
"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."
"We are not paying any licensing fees. OPNsense is completely free for us."
"It is free."
"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."
"Its pricing is unbeatable in comparison to other firewalls. You can have a small instance that could be €80 a month with the hardware underneath. Azure Firewall and FortiGate are out of the question at this price. If you are on a public cloud, you need the underlying infrastructure. Other than that, there is no additional cost. If you have it on-prem, you have to buy the server or the appliance. The hardware cost is replaced with the infrastructure cost in the cloud. You also have costs for the public IPs and underlying VMs, but that's not related to OPNsense. It would be the same for a FortiGate deployment on Azure. You need a FortiGate license, and you need the underlying infrastructure that scales up depending on your needs."
"OPNsense is a well known open-source tool."
"The solution is not expensive."
"It's not expensive."
