For me, personally within our company, I am using this for business administration, but the company as a whole uses the product as a general firewall solution.

Provides an easy and simple means of filtering traffic and establishing VPN connections and authentication
Pros and Cons
- "This is an easy means of setting up high-availabilty firewall protection."
- "The support is not very good, but the product is stable so it is not so much of a problem."
What is our primary use case?
How has it helped my organization?
This product has improved our organization by providing an easy and simple means of filtering of traffic and establishing VPN connections and authentication.
What is most valuable?
The high-availability feature is the most valuable feature for our company. It is faster and more secure by creating a situation where there are more paths and less opportunity for failure and data loss.
What needs improvement?
While the product is good and does provide services we need for authenticating and establishing VPN connections, some time ago we had issues with logins. The login event and the performance for this feature were very poor but have improved.

857,028 professionals have used our research since 2012.
For how long have I used the solution?
The organization has been using this solution for about six years.
What do I think about the stability of the solution?
Excluding the login performance — which we would have issues with in the past that made us have to turn off the feature in order to examine the infrastructure — every other feature and functionality has proven to be stable. We have also experienced some issues with performance with filtering traffic but it was on the appliance and because it was just a basic setup. The real problem was the configuration and had we been more familiar at the time, we would have done a better job with it. So it was not the product that was unstable, it was our application of it.
What do I think about the scalability of the solution?
The solution is scalable, but we really have not had too much of a reason to put the scalability to the test. I cannot imagine an issue where we would have to scale more right now as we use two hardware installations and the high-availability feature manages the traffic. Two appliances for us seems like more than enough.
How are customer service and support?
I think the technical support is not really very good. When we had some issues in the past and sent them to support, we waited a few weeks and in that time we managed to figure out the solution ourselves.
The one issue I am talking about was a very tricky issue, but they should know more about the product than we do even if we are doing the installations. Meanwhile, we had to wait and it was very inconvenient. So I think the process of the way they handle the management of issues could be improved. We managed to get some of the easier issues resolved in part through the support team initially, but when we reached the next level of difficulty, it lasted too long to get a resolution.
Which solution did I use previously and why did I switch?
We had been using our own solution and wanted to go with a dedicated, packaged product. It was a business decision and would allow us to refocus our internal resources.
How was the initial setup?
Because we have been doing installations of this product for five years, the installation is fairly easy. It was not very easy the first time but now we have a lot of experience in doing installations so, for us, it is easy to set up.
What about the implementation team?
We do not use integrators or resellers as that is what we do and it is our responsibility.
What's my experience with pricing, setup cost, and licensing?
As far as choosing the best licensing solution for your organization, do not buy the cheapest solution. Instead, buy the one that fits the traffic for your company with some room for expansion or headroom. Next year, if the business grows — which is usually what you want to do — you could reach a point where there is more traffic and the performance could become an issue.
What other advice do I have?
We have lots of experience in using and installing FortiOS, and because of the experience has mostly been positive, I recommend FortiOS as a solution for firewalling. Besides the few issues we have experienced in the past, this is a stable solution and the high-availability feature is very, very good.
On a scale from one to ten, where one is the worst and ten is the best, I would you rate Fortinet FortiOS as a nine. Despite the few problems we had in the past it is a very good solution which does what it is designed to do.

How was the initial setup?
The initial setup is complex. The deployment takes eight to nine months.
What's my experience with pricing, setup cost, and licensing?
The pricing will depend. It can depend on your partner. Sometimes your partner can get you a better price.
What other advice do I have?
I wouldn't specifically recommend one product of this type over another. We provide a plethora of products and it depends on the client's needs.
I would rate this solution a six or seven out of ten. We deal with a lot of products, this one is okay. It really depends on the client.

In terms of what needs improvement, the pricing could be lower. The price is very steep.
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.

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.

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.

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

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.

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.

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.
