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.

Associate Director IT Operations at Procento

Single-pane management has simplified firewall control and has improved risk mitigation

I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.

The intrusion detection system helps our organization by automatically detecting and responding to potential threats

The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page. The intrusion detection system helps our organization by automatically detecting and responding to potential threats. It operates similarly to Darktrace, which detects and responds automatically based on the security rules you apply. Initially, you configure everything to block, and then you can whitelist specific items as needed.

Quotes from Members

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

Pros

"The most helpful features of FortiGate include its firewall policy, specifically the user-based policy, which I find to be quite beneficial in managing our network security effectively."

"The most useful functionality of Fortinet FortiGate is the user interface, multiple engines, and their cloud with the latest integrations. Additionally, the Security Fabric tool is very good."

"The tool's most valuable feature is IPS. In my experience, I haven't encountered any issues with integration. It easily integrates with the FortiGate solution. However, verifying through documentation and assessing their support is necessary."

"The SD-WAN is the most valuable feature."

"Whenever I need something, Fortinet improves and updates the software for me."

"Simple interface and easy to deploy."

"The main benefit I have seen from using Fortinet FortiGate is the protection it offers because I can see threats that come through in real-time, and if they are blocked, I can see that."

"Fortinet FortiGate has very good support."

More Fortinet FortiGate pros

"Overall, I rate FortiOS a nine out of ten."

"Fortinet delivers a good balance of price and performance."

"A good network security system for medium-sized businesses with an excellent GUI interface that gives a graphic view of network status."

"What I like about this solution, is that it is the only solution that currently offers VPN for clients."

"Their classification inside of that database of the various threats is typically very, very good."

"As an end user, I was pretty much satisfied with Fortinet FortiOS 40F; there were no lags, no issues, and no hanging of the firewall, and once configured, unless any policy change is required, it works in such a way that you can just forget about it after configuring it because it is that smooth, robust, and sturdy."

"The most valuable features of Fortinet FortiOS are its simplicity, highly user-centric, and performs well. The line speed and for heavy traffic, is helpful for us."

"The solution provides good firewall and antivirus protection."

More Fortinet FortiOS pros

"This solution is quick and easy to configure."

"Our organization's main concern is stability, and this is a stable solution."

"I like that it works fine. Stormshield is a very good solution."

"I like how you can configure the rules. There is the task for the rules and a task for the network configuration. It also provides SMD filtering, and it can be integrated with the active directory for the users, their mission, and the VPN configuration. We are here in Sudan, and Stormshield didn't work in Sudan for more than a decade. Stormshield is a very strong firewall and very easy to configure and maintain. I am just working with the firewall solution, and we don't have any other solutions like endpoint solutions or something like that."

"The tool's most valuable feature is its dashboard, which helps you manage different aspects of a single page. The intrusion detection system helps our organization by automatically detecting and responding to potential threats. It operates similarly to Darktrace, which detects and responds automatically based on the security rules you apply. Initially, you configure everything to block, and then you can whitelist specific items as needed."

"Easily manageable in a variety of environments."

"A very robust product."

"I can see what traffic is going on. I can easily block any programs from attacks."

Cons

"For Fortinet FortiGate, their code development would definitely be something they need to improve on to reduce vulnerabilities that need to be patched."

"To improve Fortinet FortiGate, I think they need to improve the software and make updates more quickly, rather than taking a long time to update the software or firmware."

"Security level could be increased."

"There should be some open-source training or free training for decision makers, or some webinars should be available. These would help understand the new product line and the existing product line features."

"The setup is pretty complex and not easy to implement."

"I would like to see improvements in Fortinet FortiGate regarding the active-active scenario. The active-active scenario is supported but not recommended, whereas other vendors are implementing active-active without issues. Perhaps in the future, we could effectively use both firewalls to increase the throughput. If there are two boxes, they both should be able to work."

"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."

"Some features in Fortinet FortiGate need improvement as we discover when calling support that certain actions must be done from the command line."

More Fortinet FortiGate cons

"Right now, it's very trendy to integrate everything into the cloud. This solution would be more effective if they did more integration in that regard."

"It would be better if AWS instances were available. If I want to upgrade from T2.small to T2.medium, it should be available rather than having a big instance and paying a lot of money for that. The issue is that we had deployed in AWS Cloud, and we were using a very small instance. Recently we wanted to move in-house and deploy it on the big instance because it was struggling with the RAM. If we use T2.small, we cannot upgrade it to the T2.medium. It has predefined instances in the marketplace with a lot of cost differences. If I can increase the RAM, I have to choose the T3.large instance. If I'm paying $270 for the small instance, I have to pay more than double the cost for T3.large. It is about $850, and this is not good. So, it would be better if it was cheaper. I think both AWS and Fortinet should think about that. They should provide it on lower instances as well. If I want to upgrade it from T2.small to T2.medium, it should be available, but it's a problem."

"Lacks flexibility for different scenario configurations."

"I would like to see smaller and more frequent updates."

"I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle."

"It should also manage the local DSCP network."

"FortiOS could provide a more detailed analysis of the network and connected devices."

"There is no flexibility."

More Fortinet FortiOS cons

"The filtering configuration could be better. We have some difficulties with the filtering configuration and the filter extension. It's not that easy. It's not that straightforward. In the next release, I would like to see a reporting system. Stormshield doesn't have any tutorials on how to do the configuration and things like that. They just have documentation on the website. If you want to configure, for example, Cisco or Fortinet, you can find tutorials on YouTube. They show you how to configure the features, and so on. In Stormshield, there is nothing on social media or the internet on how to configure different things. The lack of documentation or the lack of material makes it difficult for others to adopt this solution."

"Improvement is needed in terms of the technical support of the manufacturer."

"A more user-friendly interface would be helpful."

"The SD card could be more secure."

"Stormshield Network Security is quite expensive."

"It could be better if it were more user-friendly. It's too complicated for us to use it. The price could be better as well."

"The product must improve its pricing."

"Not all the fields are activated yet and we were informed that it will take at least one month."

More Stormshield Network Security cons

Pricing and Cost Advice

"It is around $50,000 per month."

"The solution is cheap."

"Fortinet has one or two license types, and the VPN numbers are only limited by the hardware chassis make."

"We are on an annual license to use Fortinet FortiGate."

"Pricing is lower than Cisco."

"On a scale of one being cheap and ten being expensive, I rate the tool's price as an eight."

"Its price is reasonable. They have a clear pricing policy. It is not complicated by the number of VPN users at a time. We know what the price is. The yearly subscription for the security license is rather high, but it is all included for whatever number of users you have and the kind of functions you need."

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."

More Fortinet FortiGate pricing and cost advice

"We pay an annual license fee. It is rather expensive so I would like to perhaps see a drop in price in the future."

"The licensing for FortiOS is good, with a security license included when we update the main license."

"The program is expensive."

"We had a three-year license to use Fortinet FortiOS and we are going to renew it this year."

"The solution is cost effective. I would rate the pricing a five out of ten."

"The best solution in the category including the price in Thailand is Fortinet FortiOS."

"I am on a two-year contract and I pay annually for Fortinet FortiOS."

"The scalability of Fortinet FortiOS is good. However, central management is intuitive for the end-users. We had a lot of questions about central management, and sometimes they didn't use it and did their firewall management directly on FortiGate instead of using Fortinet FortiOS."

More Fortinet FortiOS pricing and cost advice

"The SN200 series costs between $500 USD and $600 USD per year, whereas the SN700 series costs approximately $1,000 annually."

"We chose Stormshield for its price, as the Azure firewall was too expensive."

"The price of this solution and the price of support are ok."

"I think the price is good."

"The pricing could be better."

"For mid-sized companies, they sell their appliances for good prices."

"We bought a three-year license, and we renew it whenever it expires. The price could be better. It's always very expensive."
