Featured Reviews

Jorge Martínez - PeerSpot reviewer
Offers good SD-WAN capabilities and integrates easily with Fortinet devices
I am not part of the initial setup or deployment process since I work in presales. The setup or deployment is quite easy, as you can do a one-touch deployment that automatically connects to the FortiManager cloud when you connect it to a broadband or dynamic IP, allowing you to start the configuration from that point. We usually sell it for on-premises setups. It's on the cloud only when the client has virtual machines or their own service. Sometimes they have a service on the cloud like AWS, but it's more difficult to sell now because AWS has an e-commerce option where you can buy FortiGate directly. The only thing you need is someone to manage and configure.
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

"Layer-3 firewall and routing are the most valuable features."
"FortiGate's web and URL filtering are unlike any other firewall I've used. The functionality of URL filtering in those solutions is problematic because everything is encrypted, and firewalls can't break that encryption protocol. Fortinet has an SSL proxy, so the encryption is done before the packet ever leaves the FortiGate. The URL filter is definitely one of the most helpful features."
"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."
"Reliability is the best feature. We faced some issues when we were setting it up, but the service, portal, and administration are good."
"Fortinet FortiGate has many valuable features, such as IDS, and intrusion detection. It has security features that are in part with the technologies that are available in the market."
"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."
"We are very happy with the general bandwidth agility we have seen from one website to another website."
"The biggest lesson would be that Fortinet FortiGate provides a high level of security at a good total cost of ownership."
"Azure Firewall's feature that I have found most valuable is its scalability."
"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."
"We secure the entry point to the virtual data center with the firewall."
"I think that one of the best features is definitely the premium version, along with the IDPs in terms of the intrusion detection and prevention system."
"The feature that I have found the most valuable is the control over the network permissions and the network."
"The solution is very stable. When comparing it to other environments, it's actually quite impressive."
"It's auto-scalable, which is a great feature."
"The solution is stable."
"The most valuable features are reporting, the Sensei plugin, and firewall capabilities."
"The tool's integration is more like a button press."
"It has firewall and VPN capabilities, which are very valuable features."
"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 have been operating here in our lab for several months, and everything appears to be extremely stable."
"The initial implementation process is simple."
"OPNsense is easy to use and open source."
"One of the most valuable features is the network checking. Additionally, the firewall and web filtering functionalities are highly useful."
 

Cons

"Fortinet needs to overhaul its documentation."
"I would suggest that Fortinet add sandboxing to their solution."
"If they had better integration with security products, such as Cisco ISE or Rapid Threat Containment, then it would be an improvement."
"I use the FortiGate 60D model and realized the 300Mbps bandwidth limitation. Because it is a product that offers many services, I think it could have greater bandwidth capacity."
"I would like to see a more intuitive dashboard."
"We would like to have the ability to disable some of the security functionalities."
"One area for improvement is the performance on the bandwidth demands for smaller devices, as well as better web filtering."
"Fortinet doesn't provide multiple virtual firewalls which would facilitate end users and customers."
"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."
"The tool needs to improve the onboarding and transition process for on-prem users."
"Right now, with Azure Firewall, we cannot have a normal inbound traffic flow. For inbound, Microsoft suggests using application gateways, so the options are very limited. I cannot use this firewall as an intermediate firewall because of the limitations, and I cannot point routing to another firewall. So if I want to use back-to-back firewall architecture in my environment, I cannot use Azure Firewall for that type of configuration either."
"It would be nice to be able to create groupings for servers and offer groups of IP addresses."
"They can improve the pricing of Azure Firewall."
"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."
"There is room for further integration of AI into the system."
"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 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."
"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 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 logging could improve in OPNsense."
"The solution would not be suitable for anything large-scale."
"There is room for improvement in SSL inspection."
"They should improve IPEs for security in the future."
"The ability to set the VPN IP address would be a welcome addition."
 

Pricing and Cost Advice

"The license is too expensive to renew. The license renewal process is also complex."
"The main reason we chose Fortinet FortiGate was that the price was better than the competition."
"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."
"The price is high compared to some of the other solutions."
"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"The licensing costs are very low."
"Fortinet FortiGate is expensive."
"The price of FortiGate is reasonable as I plan to buy new switches. The initial gadgets are already booted, and the pricing seems normal on the market. As for additional costs, I haven't subscribed to many extra features, so I'm only using what I need. Last year, I renewed the support for three years, which can sometimes be expensive but depends on the security benefits and how it helps us."
"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."
"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."
"Azure Firewall is expensive."
"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."
"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 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."
"There are no licensing costs for OPNsence."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"I would rate the pricing three out of ten."
"It is open source and free."
"It costs about $1000."
"OPNsense is an open-source solution and it is free to use."
"It is free."
"It's a free solution."
