Our primary use case for this solution is for deploying network security systems for SMBs or mid-range corporations.
IT Consultant at a tech services company with 51-200 employees
Cost-effective solution for medium-sized businesses and mid-range corporations but it has some product limitations
Pros and Cons
- "A good network security system for medium-sized businesses with an excellent GUI interface that gives a graphic view of network status."
- "While it is a solid solution, there are some product limitations which exclude it from deployment in some situations."
What is our primary use case?
How has it helped my organization?
We use the SSL VPN web portal and we actually find it very useful because we don't need to bother with installing additional client-side software.
What is most valuable?
The most valuable part of the application is the graphic user interface of the application where you can see specifically what's going on in the system at a glance and quickly assess the system. The GUI is very good.
What needs improvement?
One thing that should be improved in future versions is an issue we have observed and had problems with a few times. When we try to reinstall a backup for FortiOS, you need to do a factory reset manually or you lose access to a device. I have experienced this situation a few times and it seems like something that should not be required and they should resolve.

881,082 professionals have used our research since 2012.
For how long have I used the solution?
We have been using the product for about five years.
What do I think about the stability of the solution?
I think the product is a pretty stable solution. I did have some cases with the webserver where the appliance actually crashed. Later I research about the issue and I found out that it was actually a bug in the latest version. I imagine that because they know they will issue a fix if they have not already.
What do I think about the scalability of the solution?
I recommend this product to my clients partly because of the scalability. Scaling is never really a problem though it may cost more if the client requires additional licensing or hardware.
How are customer service and support?
I don't often have to contact support. When I do I usually just get help from the online community. I really don't contact their support directly.
How was the initial setup?
I go about initial setup by just implementing the configuration using CLI (Command Line Interface) to propagate the components. I think the initial setup is straightforward.
What about the implementation team?
We are the consultants and we do the installations.
What's my experience with pricing, setup cost, and licensing?
I think the cost of the product categorizes FortiOS because it is a bit more expensive than small businesses will usually want to spend. It is not really practical for SMB or for small businesses. It is mostly for mid-range or higher SMBs because of the pricing. It is not expensive compared to some products, but a small business may not justify the cost. The cost ends up being dependent on the solution you choose and if you want individual or package licensing.
Which other solutions did I evaluate?
As consultants, we provide different customers with different solutions based on what they need. So, there is no specific product that we evaluate as there are always several options. Mainly I use Fortinet or Sophos solutions to recommend to my customers. We will use on-premises or cloud depending on the needs and how it fits for the client. For Fortinet FortiOS we usually use it in on-premises installations.
What other advice do I have?
I do recommend this product to clients for use but it depends on their case needs. For example, in the AAA (Authentication Authorization and Accounting) some of the accounting and some of the VPN tunneling features are removed from Fortinet FortiOS due to some security configurations. In some projects, we need those features for the client and when that is the case, I cannot recommend that the client use the FortiOS solution.
It would be a better product if there were a logging feature. You need to have FortiAnalyzer in your installation to have logging management capabilities. It will be a better solution if some logging and history capabilities were integrated without requiring an additional product installation.
On a scale from one to ten, where one is the worst and 10 is the best, I would rate Fortinet FortiOS a seven. It is a good product but there are a few problems.

A stable solution with an easy initial setup, even for non-technical users
Pros and Cons
- "The solution is extremely scalable."
- "The solution needs to adjust its pricing models. With the way they are structured, everything is very disparate and sold separately, and, depending on the solution, it can get quite pricey."
What is our primary use case?
We primarily use the solution for protecting our virtual infrastructure.
What needs improvement?
The solution needs to adjust its pricing model. With the way they are structured, everything is very disparate and sold separately, and, depending on the solution, it can get quite pricey.
The solution could be more intuitive. Especially when customers have access to it, it's not as simple and straightforward as some of the other devices I've taken a look at.
For how long have I used the solution?
I've been working with the solution for five years.
What do I think about the stability of the solution?
The solution seems very stable once you have everything up and running.
What do I think about the scalability of the solution?
The solution is extremely scalable.
How are customer service and technical support?
Technical support is good. I would rate them nine out of ten.
How was the initial setup?
The initial setup is pretty straightforward.
It wasn't technical people doing that deployment for the proof of concept, so it took about a day. We also hadn't set up all the features and capabilities.
What's my experience with pricing, setup cost, and licensing?
We pay $100,000. That covers the cost of the hardware that we run the VN's on. That also includes any SGNA costs for the internal support tech.
What other advice do I have?
We use the private cloud deployment model.
I would rate the solution nine out of ten.

Director Of Hosting Services at a tech services company with 51-200 employees
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?
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.
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.
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 technical 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.

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

Has good caching features but technical support needs improvement
Pros and Cons
- "The most valuable feature of this solution would be the caching feature."
- "Their technical support needs improvement."
What is our primary use case?
We use different types of deployment models of this solution besides for the public cloud. Our primary use case is to install it for many clients on their on-prem site. Our job is client-based. We are resellers of this solution.
What is most valuable?
The most valuable feature of this solution would be the caching feature.
What needs improvement?
Their technical support needs improvement.
All products have pluses and minuses. It will depend on a client's use case.
For how long have I used the solution?
We have been using Fortinet FortiOS for around eight to nine years.
What do I think about the stability of the solution?
The stability is good.
What do I think about the scalability of the solution?
Scalability is good.
How are customer service and technical support?
Sometimes it is difficult to get support. It can take time to get an answer to our problems. They don't always know what the solution is.
They also offer online support.
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.

Technical support offers good regional support and it has good scaling options
Pros and Cons
- "It has a lot of scalability abilities which makes it easy to scale."
- "In terms of what needs improvement, the pricing could be lower. The price is very steep."
What is our primary use case?
We use the on-prem deployment model of this solution and on the cloud. Our primary use case of this solution is for bandwidth management and VPN.
What needs improvement?
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. It should have an appliance that can be used to support and manage other access points. All the products should be uniform and easy to find.
For how long have I used the solution?
I have been using Fortinet FortiOS for around three years.
What do I think about the stability of the solution?
It is quite stable. It is easy for me to integrate interfaces.
What do I think about the scalability of the solution?
It has a lot of scalability abilities which makes it easy to scale.
How are customer service and technical support?
Their technical support is quite good an informative. They also offer regional support which has been good. We are satisfied.
How was the initial setup?
The initial setup was straightforward.
What other advice do I have?
I would rate this solution an eight out of ten. I would recommend it to someone considering it.

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."
- "In the future I would like to see more user-friendly dashboards and a drop in the price."
What is our primary use case?
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
What is most valuable?
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.
