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.

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.

Though it helps deal with web traffic or any malicious traffic, it needs to work on its DC performance issues

The product's initial setup phase is moderate in level, so it is neither very complex nor very easy. For the deployment, my company first needs to gather all the requirements of the users and the domain names and consider how many users there are in the company. In the implementation and planning part, my company needs to consider what kind of policies we will create while ensuring that the policies are created based on the requirements of the users. There is a need to segregate the users' requirements since there are separate departments in the company, like the HR department, sales department, IT department, and manufacturing department, so that our company can create policies depending on their requirements. On-site, if you want a GRE tunnel, our company can handle GRE tunnel traffic routing and Zscaler Cloud Firewall, after which Zscaler will take action based on the policies created by our organization. For the deployments and maintenance, a team of five members consisting of two managers and three engineers is required.

Quotes from Members

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

Pros

"The GUI is good."

"It is stable and easy to use. There are a lot of good resources available on the web."

"It's a firewall that secures our internal network. I have been using it since 2013, and I find that most of the features are advanced, and very user friendly."

"I find Fortinet FortiGate to be quite stable, as I have never heard of any issues where they broke or malfunctioned; they are always working."

"Overall, I would rate Fortinet FortiGate a ten out of ten."

"The most valuable features are the enterprise modeling and the simple interface."

"Fortinet FortiGate is easy to use."

"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."

More Fortinet FortiGate pros

"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."

"One of the best features is that it natively integrates with Azure Services and tools. When you have a third-party offering, that is not the case. But Azure Firewall provides a comprehensive and seamless security solution for your Azure resources."

"Azure Firewall is a cloud-native solution that removes the pain of load balancers."

"The product's value to my company stems from its ability to secure my organization."

"The solution should be capable of self-scaling, which is one of the features we like about it."

"Network filtering is valuable. The scalability capability from the cloud-native service helps us a lot because it simplifies our day-to-day maintenance activity."

"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."

"Azure Firewall integrates well with multiple platforms."

More Azure Firewall pros

"The technical support from Zscaler was excellent."

"The solution offers good sandboxing."

"Includes advanced tech protection."

"Zscaler Cloud Firewall understands the applications in the current generation and adapts to the present generation cloud applications."

"Once you have Zscaler running you have access to configure it however you want."

"Zscaler is still a very good product."

"I like the ease of deployment and its flexibility. We don't need to deal with license, quotes, procurement, delivery, and installation. Everything is software-based, and it's very easy to operate."

"Since it is really customizable, I can use it and avoid enabling access to the full network."

More Zscaler Cloud Firewall pros

Cons

"Fortinet FortiGate should improve the VPN tokens."

"I wish that they could integrate zero-trust technology into Fortinet FortiGate. I am not sure whether it has been done already, but if they could implement that, it would help significantly."

"FortiGate support could do some improvements on their IPv6 configuration. Right now it's still in the very early stage for utilizing in an enterprise level network environment."

"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."

"There are some problems that support cannot give you a logical reason as to why it happened. For example, I had a case where I was dealing with a WhatsApp application that was giving issues. Technical support gave more than one reason it could be giving issues, but none of them solved the problem. Eventually I solved the problem, but it was far from the solutions that support had given."

"I don't like that anything more than very basic reporting is not included."

"Price, of course, can always be more competitive or better."

"Scalability is one of the disadvantages. When it comes to scalability, you have to actually change the box. If you want to upgrade it, you need to actually change the existing box and probably you take the system off to other sites."

More Fortinet FortiGate cons

"The product pricing could be more competitive."

"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 development area and QA area could be improved. With those improvements, we can improve projects and take even less time to implement them."

"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."

"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."

"An Azure firewall is not a real firewall."

"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 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."

More Azure Firewall cons

"There are several areas for improvement. Firstly, the GUI is outdated, with noticeable lags and delays, especially when generating reports for past transactions."

"I don't have the visibility of a control dashboard or a network management system."

"There are some areas it could improve when it comes to blocking, we have to block some things manually. For example, if we block a top-level domain we have seen that the new IPs come through, the IPs are not blocked. There should be some more granular way of doing it. My only request is if you're blocking something at a top level, the sub-level sub-domains and all those other IPs should be blocked too automatically."

"Pricing is a challenge."

"It would be better if they improved their policy, package visibility, and flexibility while we're creating rules for inspection. It could also be cheaper or more things could be included in the basic package. In the next release, I would like better coverage in the Asia Pacific region and better quality of service."

"The issue right now is probably that Zscaler is not providing web browser isolation. Another solution, Menlo, offers this. For one customer, we had to send traffic to Menlo to do the isolation for us. It was requested by the customer so that they could integrate any iframe. Zscaler needs to add this type of feature in their next release."

"Certain criteria need to be met if you want to scale this solution."

"Because it's on cloud, it doesn't allow application of extra settings."

More Zscaler Cloud Firewall cons

Pricing and Cost Advice

"The price is highly competitive when compared to other brands that offer similar functionality."

"Fortinet's pricing is more straightforward than other solutions. If Fortinet doesn't stick out when you're searching for a solution, you are a glutton for punishment. You only need to know two things when purchasing a Fortinet solution: your total bandwidth and bandwidth at the site. You need to estimate the future bandwidth with other solutions if your customer plans to upgrade."

"Each feature costs money, so it is important to study your needs."

"The license is too expensive to renew. The license renewal process is also complex."

"Fortinet FortiGate is cost-efficient. Palo Alto is expensive, but Fortinet FortiGate is not."

"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."

"It's very competitive."

"Pricing for this product is comparatively lower than other products. It's an affordable solution, but when expanding the number of users, they'll ask you to replace the model, so that's an added cost."

More Fortinet FortiGate pricing and cost advice

"The licensing module is good."

"The total cost of ownership is much less than Palo Alto, Cisco, or any other brand."

"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 solution is cheaper than other brands. My company has an enterprise contract and we finally got a good price with Azure."

"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."

"Before choosing this solution, we evaluated others, and we found this to be the most cost-effective."

More Azure Firewall pricing and cost advice

"There is an annual license required for the use of the Zscaler Cloud Firewall."

"It is not the most budget-friendly solution, but it's important to consider its overall value."

"It is expensive for small businesses."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight out of ten."

"There are different subscription models available."

"The product is a bit expensive compared to the solutions offered by its competitors, like Palo Alto. There is a need to make yearly payments towards the license in charges associated with the product."

"Zscaler is priced too high compared to the cost of Fortinet."

"The licensing is on a yearly basis. It is somewhere around 30 or 40 pounds per user for our organization."
