Pros and Cons
  • "The solution is very easy to configure and has a good interface, plus it offers more configuration options than other vendors."

It has optimized the WAN environment for connecting users to the application
Pros and Cons
  • "Fortinet has optimized the WAN environment for connecting users to the application."

How has it helped my organization?

Useful UTM features, good interface, and beneficial controls
Pros and Cons
  • "The interface is good."
  • "There are some features for FortiGate using FortiOS that can only be enabled via a command line. These aren't very advanced features they have been part of FortiOS for quite some time but they still aren't accessible from the graphical user interface. It makes it a little bit harder than it should be for us to manage the solution. That's my main concern with the user interface. Another concern we have is some elements for the user interface, if they're not properly configured, it could lead to hardware and performance degradation."

What is our primary use case?

Most of our customers that we implemented Fortinet FortiOS for we support and manage the FortiGate. Most of them use all the UTM features, such as web features, application control, intrusion prevention, and SSL inspection. We do have some customers who do not use these features. They mostly use IPsec, VPN concentrator, but no security features, we only have two specific cases. Most of our clients prefer to use FortiGate because of all the security features.

What is most valuable?

The interface is good.

What needs improvement?

There are some features for FortiGate using FortiOS that can only be enabled via a command line. These aren't very advanced features they have been part of FortiOS for quite some time but they still aren't accessible from the graphical user interface. It makes it a little bit harder than it should be for us to manage the solution. That's my main concern with the user interface. Another concern we have is some elements for the user interface, if they're not properly configured, it could lead to hardware and performance degradation.

We have had some cases where the entire hardware is at a lockout. This means the CPU is  100% consumed and requires a reboot because of a malfunction with the graphical user interface dashboard widget. This is something that we saw a few years ago. We haven't had any new experience with this same issue. However, I'm not sure if that's because Fortinet fixed them, or because we have mow avoid using those specific regions.

For how long have I used the solution?

I have used Fortinet FortiOS within the last 12 months.

What do I think about the stability of the solution?

Fortinet FortiOS is stable.

What do I think about the scalability of the solution?

I have found Fortinet FortiOS to be scalable.

We have approximately 200 users using this solution.

Which solution did I use previously and why did I switch?

We have used work with many antivirus solutions, such as Trend Micro, CrowdStrike, and Kaspersky. The antivirus engine could use some improvement when comparing Fortinet with other vendors.

How was the initial setup?

I have been doing the installation of Fortinet FortiOS for five years and I am used to doing them. For someone who is new, I do see some difficulties for them to learn how to do it.

The process could be better.

What about the implementation team?

For approximately 200 employees we have at least two engineers and some junior analysts for the day-to-day operation.

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

The Fortinet solutions can be a bit expensive.

What other advice do I have?

The most advanced solution Fortinet has is intruder prevention.

My advice to those wanting to implement Fortinet FortiOS is they should do a site survey, but not exactly the site survey. They need to study and scale the environment for which they want to implement the FortiGate solution. FortiGate solutions aren't exactly cheap, but if they undersize the environment and they purchase or implement FortiGate solutions that are not good enough power-wise for the environment that's being used, it could lead to problems. Although it is a stable solution, it is prone to lockouts if it goes above the recommended use cases. Proper sizing of the environment is very important.

I rate Fortinet FortiOS an eight out of ten.
