We use the on-prem deployment model of this solution. We use the standard model for our clients.

Easy setup and has good stability
Pros and Cons
- "The initial setup is easy. It's the easiest firewall installation process on the market. I work with three or four other products and this one is the easiest."
- "In terms of what needs improvements, the troubleshooting could use improvement. When we work with other products like Cisco ASA, Palo Alto, and Check Point, we see a big difference in the troubleshooting. It's not easy to find a report."
What is our primary use case?
What needs improvement?
In terms of what needs improvements, the troubleshooting could use improvement. When we work with other products like Cisco ASA, Palo Alto, and Check Point, we see a big difference in the troubleshooting. It's not easy to find a report. In order to overcome the problem, you have to install FortiAnalyzer to help you find the troubleshooting problem. FortiOS has its limitations.
What do I think about the stability of the solution?
I work with many products but this is the most stable OS I have seen. With Cisco, for example, if you do an upgrade, it's not guaranteed that the production will be stable. The upgraded release will release many bugs. FortiOS isn't like this.
There is something called Fortinet Fabric that helps you to enforce your security by connecting all of your products with FortiGate. For example, if you install FortiClient on your PC it will help you use the VPN and the antivirus. When there is an issue, if you have 1,000 users with FortiClient will send a message to FortiGate. I have many projects and I use FortiManager to manage them. It helps my team minimize implementation time.
What do I think about the scalability of the solution?
We have thousands of user using this solution. Only one person is required for the deployment.

How are customer service and support?
Their technical support has its positives and negatives. If you contact them, they are responsive and interactive and they have good solutions to the problem. The issue is with the support documents. When you need to do something advanced, there isn't good documentation for it. For basic tasks, there are plenty of videos and information but for advanced tasks or solutions, there is not.
How was the initial setup?
The initial setup is easy. It's the easiest firewall installation process on the market. I work with three or four other products and this one is the easiest.
The time it takes to deploy will depend on the needs of the company and how complex they are. A basic installation will take one hour.
What other advice do I have?
It's important to have 24/7 support because the documentation is poor and you will need the support. It's important to have a support team and a support contract.
I would rate it a nine out of ten. Not a ten because of the troubleshooting. Other solutions have a mechanism to find your IP network. Cisco has something called Packet Tracer which is very advanced that helps you test your configuration. It really helps the engineers to test without affecting the product environment.

What's my experience with pricing, setup cost, and licensing?

I would like to see in the next release that any client, even small ones from a home office, can run on any access point, not just the one that can be used with Fortinet.

Very stable and scalable with great technical support
Pros and Cons
- "What I like about this solution, is that it is the only solution that currently offers VPN for clients."

We use Fortinet FortiOS as a perimeter firewall. On top of that, we use another application as a web application firewall.
How has it helped my organization?
Great logging analsys with fortianalyzer

FortiVPN I think is the only one vpn that can be shared with customers and employees, however another features is FortiVM that allow us to have onne solution from Onpremise datacenter to cloud datacenters.
What needs improvement?
Docker Container to have a good integration with kubernetes and more throughput as Cisco FP
For how long have I used the solution?
I've been using Fortinet FortiOS for five, six years now.
What do I think about the stability of the solution?
My impression of the stability of the solution is good just one support case opened to fortinet, in next firewall update I will choose again fortinet
What do I think about the scalability of the solution?
We currently have 200 users, and we plan to increase them, so I believe in his scalability while users increase.
How are customer service and technical support?
The technical support is great, good solutions and an excellent proactivity.
Which solution did I use previously and why did I switch?
I used Palo Alto NG Firewalls before but I wasn't impressed by the features it offer and the price was also too high.
How was the initial setup?
I did the installation myself but I can't remember if the initial setup was easy. I remember the deployment took about five days. It was very long ago, so I can't remember well.
What about the implementation team?
I've implemented it by myself with another colleague, probably in next firewall update I will engage the vendor team.
What's my experience with pricing, setup cost, and licensing?
We pay an annual license fee. It is rather expensive so I would like to perhaps see a drop in price in the future.
Which other solutions did I evaluate?
I didn't evaluate other options because I like the experience I had with Fortinet, so I simply prefer Fortinet.
What other advice do I have?
My advice to other customers would be to have good knowledge about the traffic in their network. In the future, I would like to see more user-friendly dashboards and a drop in the price. My rating for this solution is therefore only eight out of ten.

Our primary use case of this program is for application control and internet commitment.

A feature-rich and stable solution, but the GUI needs to be improved
Pros and Cons
- "All of the features in this solution are effective and efficient."
- "The GUI could be improved to make it more usable, easier to administer, and easier to configure."
What is our primary use case?
I am a consultant, and I have worked with solutions from many different vendors. Depending on what the customer wants, we help to select the solution. This is one of the solutions that I have serviced in a client environment.
What is most valuable?
All of the features in this solution are effective and efficient. They are dependent on the environment in the organization.
What needs improvement?
The policies and the way that they are applied can be improved. It could be more direct, as it is an issue for some people. Generally, policy management could be made better and simpler to deploy.
The GUI could be improved to make it more usable, easier to administer, and easier to configure.
For how long have I used the solution?
I have been working with this product for several months.
What do I think about the stability of the solution?
I think it's a stable solution.
What do I think about the scalability of the solution?
We have been deploying this solution in small and medium-sized environments, with no more than fifty users, and it has always been effective.
How are customer service and technical support?
I don't think that we have had any issues with technical support for this solution.
How was the initial setup?
The difficulty of the initial setup depends on who is handling it. Definitely, there are challenges, but if you have a proper understanding of what you're supposed to do, then it is straightforward to work with.
For me, I think that the physical box is more straightforward to work with, but it depends on who is doing it. If you get your architecture right then it is a pretty straightforward deployment. If you don't, then you run into issues that you will need to troubleshoot.
What other advice do I have?
For my requirements and expectations, I would rate this solution a seven out of ten.

Technical Consultant at ezz elarab
Good configuration, easy to use, and offers various functions
Pros and Cons
- "I like its configuration and the various functions it offers."
- "For me, it is important to be able to block VPN applications, like Facebook, so I would like to see that included in the next release. With this version, if you want to block or allow a site, you now have to drag all the domains related to this site."
What is our primary use case?
We primarily use the solution as a data center.
What is most valuable?
Fortinet is very easy to use. I like its configuration and the various functions it offers.
I think the most common use for a firewall system is web filtering and application filtering. The program has other features too, like anti-virus and other security features, but I think that some of the usage is there to control and connect web filtering and application filtering and to control what comes in and what goes out.
What needs improvement?
For me, it is important to be able to block VPN applications, like Facebook, so I would like to see that included in the next release. With this version, if you want to block or allow a site, you now have to drag all the domains related to this site.
For how long have I used the solution?
I've been using the solution for three months now.
What do I think about the stability of the solution?
The program is very stable.
What do I think about the scalability of the solution?
The scalability is very high.
How are customer service and technical support?
The customer service is very nice because they answered my questions when I asked them about the program before buying it. The technical support is great too, because they called me back with a solution to my question.
How was the initial setup?
The initial setup was straightforward and I did it myself. I downloaded it, read the instructions and started the deployment, which took only about an hour.
What other advice do I have?
I rate this solution an eight out of ten and I will definitely recommend it to others because many people are using it around the world now.

Head of Infrastructure Network at innovectives
Excellent integration with an open API and a very easy to use interface
Pros and Cons
- "The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly."
- "The solution is good, but they have poor marketing in Nigeria. They need to market their product better."
What is our primary use case?
We primarily use the solution for banks, whereby they want to secure their edge network, to filter their web application and block forms, etc. We also are able to integrate AWS using secure channels. It's more robust and they have different modes including nap, flow, and proximity.
What is most valuable?
You can apply patterns to look for. That can be done for applications also. You can ask for a specific feature to become a pattern. If you were using Office 360 and had 2 ISPs, automatically using SD-WAN will allow you to switch over to the other link based on the criteria you can set yourself. You don't need to go to the device to manually sort and link it, it does it automatically.
Users can go directly to the cloud from the branch instead of routing to the head office and then the cloud. That will reduce the cost of routing, so you just pay for internet service and you have access to the cloud.
The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly.
What needs improvement?
The solution is good, but they have poor marketing in Nigeria. They need to market their product better.
They need to work on their support. Cisco has the best technical support. In comparison, Fortinet's support takes too long. If you are paying for SLAs, you should also get value from your SLAs.
Right now, everybody is moving to the cloud. The solution has already worked on that aspect, and they are embedding security to the cloud. However, security can be more enhanced and as long as they continue to offer more protection I'll be happy.
For how long have I used the solution?
I've been using the solution for five years.
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
The solution is very scalable. It allows for API integrations so you can actually integrate into other security solutions.
How are customer service and technical support?
Technical support could be more qualified and offer a quicker turnaround.
How was the initial setup?
The initial setup is very straightforward, especially if that person understands security.
Which other solutions did I evaluate?
We integrate solutions on the client's request. Most times I push on Fortinet, as it's a robust system.
You can integrate your endpoint with Fortinet. You can integrate the cloud on-premises. Because the solution is so robust and offers excellent the features we tend to enjoy using FortiOS. Cisco is similar, however, and we do work with them too.
What other advice do I have?
We are using the on-premises deployment model.
We are an integrator, so we do integrations using Fortinet, Cisco, Sophos, and Palo Alto.
If you're an SMB or a small enterprise, I would recommend Fortinet.
I would advise users to make sure they are getting value for what they are paying for. I can say that Fortinet is not as expensive as the others, but it also gives good value. The main thing is not about the cost, but the value and Fortinet delivers on that front.
I would rate the solution nine out of ten.
