Great security and authentication but the setup can be complex
Pros and Cons
- "The classification of the websites is helpful."
- "There is no flexibility."
What is our primary use case?
What is most valuable?
Security and authentication are the most valuable aspects of the product. The classification of the websites is helpful.
The solution is stable and reliable.
What needs improvement?
We have several access points on FortiGate, which were procured long ago. Those are not supporting the present firmware update we make on the UTM. Therefore, we cannot get the latest firmware updated on the UTMs. I was thinking that if we need to get rid of these physical devices, we should move to some cloud-based system.
The only problem that we are facing at the moment is that all the devices of FortiGate, whether it is for FortiGate's access points or authenticator or controllers or UTM, is in the FortiOS. They are interrelated and interdependent. It means if I buy a FortiGate car, I have to run FortiGate OS, I have to fill in FortiGate fuel, and I have to run it on a Fortinet road. I can’t mix and match it with different solutions. There is no flexibility.
The initial setup is a bit complex.
We would like to have NMS built into the solution.
For how long have I used the solution?
We’ve been using the solution for the last ten years.

What do I think about the stability of the solution?
The solution is stable. We’ve never had any issues with the product. It’s reliable. There are no bugs or glitches.
What do I think about the scalability of the solution?
If I need to scale it up, then again, I have to change the entire family of it.
The amount of users connected at any given point is something around 6,000, including the students and the people on move.
How are customer service and support?
We never use tech support from Fortinet. We get support from a local supplier.
Which solution did I use previously and why did I switch?
We are tied to Fortinet and therefore did not use any other product.
How was the initial setup?
Initially, the solution can be a bit complex to set up. It’s not simple. There’s a learning curve. You need to train on it a bit first.
We have ten to 12 people on hand who are specialized in FortiOS and can handle deployment and maintenance tasks. We have a total of 20 people working on maintenance.
What's my experience with pricing, setup cost, and licensing?
The pricing is pretty high. I’d rate it at a two or three out of five in terms of affordability.
Since the pandemic, a lot of things have gotten exponentially higher. Also, for us, the final price is dependent on the dollar conversion rate. You can get a license for one or up to five years.
Which other solutions did I evaluate?
Since we are tied to Fortinet and could not use anything else, we did not compare it to other solutions.
What other advice do I have?
We are customers and end-users.
I’d rate the solution seven out of ten.
I’d recommend the solution for an enterprise user. However, it may be a bit much for a small or medium-sized organization.
Which deployment model are you using for this solution?
On-premises

You need to repurchase a license every year or two. Costs are negotiable and sometimes they offer promotional prices. A yearly subscription might be around $20,000 to $30,000.
What other advice do I have?
We're a customer and end-user.
We would recommend the solution.
Fortinet is a good product. However, other products are good as well. It really depends on the customer experience.
I'd rate the solution seven out of ten due to the cost of quality of services, and due to the fact that we know other firewalls are more powerful than Fortinet. That said, Fortinet is very economical and gives us an appropriate solution based on what we require.

We enlisted some assistance with the implementation process. The setup was pretty easy. It wasn't overly difficult.
We have three people who are able to maintain the solution. They include me and two team members who are both engineers.

Flexible, easy to use, and meets our requirements
Pros and Cons
- "It's easy to use."
- "Right now, all the features meet my requirements."
What is our primary use case?
FortiOS is just an operating system. That's it. It's a firmware FortiGate is running.
FortiOS is the foundation of the Fortinet secured fabric.
How has it helped my organization?
You can have virtual domains. On top of each virtual domain, you can see the independent system. When comparing Fortinet with other vendors, the good part is you can set different priorities. It depends on different VDOMs. In my case, I have two VDOMs. One is called a VPN VDOM; the other is called a web filter VDOM. Usually, for other vendors, no matter how many domains, just one primary device is always a primary one. However, for FortiGate, you can separate them. In my case, I have machine one, and machine two. FortiGate one, Fortigate two. And for each FortiGate, we can have multiple VDOMs. In my case, I have two VDOMs. If you want to save money, you can split the workload, and this capability helps us save on costs.
What is most valuable?
It's very flexible firmware.
I really like it overall. It really meets lots of my requirements.
The initial setup is easy.
It's easy to use.
The solution is quite stable.
What needs improvement?
Right now, all the features meet my requirements. It's not lacking in any way.
For how long have I used the solution?
I have more than ten years of experience with the solution.
What do I think about the stability of the solution?
The stability is good. There are no bugs or glitches. It doesn't crash or freeze. It is reliable. In terms of hardware. We are in a cycle right now to handle hardware replacement. We've been using the hardware for seven years now.
What do I think about the scalability of the solution?
I have more than 400 stores nationally in Canada. I have it in every different location. For each store, for business continuity purposes, we have two internet connections. One is the primary internet connection; the secondary is the LTE.
LTE is expensive, so we always use the primary, like cable or PPPoE. Unless the cable or PPPoE fails, then we switch traffic to LTE. Even for LTE, we control the traffic. For example, we have backup traffic. For LTE, we don't allow the backup traffic to go through LTE since LTE is for business continuity purposes only.
For redundancy, you build up the HA environment, meaning, at a minimum, you have two devices to work together. The secondary is always just sleeping there, dormant. When the primary fails, then you switch over to secondary.
However, for Fortinet, on top of this, you can have multiple VDOMs.
How are customer service and support?
I'm a very senior tech guy, and therefore I would rarely need their services. However, I will say they have been much better, and we find them helpful.
Which solution did I use previously and why did I switch?
I've had previous experience with Cisco products.
How was the initial setup?
The initial setup is very good. I'm a Cisco guy; I'm used to the command line interface. Therefore, right now, from my command line point of view, I like it. The hierarchy of the command line is very clear and it's very easy to change as needed.
What's my experience with pricing, setup cost, and licensing?
The license is based on the machine itself, not on how many users. That's why we backhaul all the internet traffic to my head office, so in my head office, I only need to buy one license. To access the internet, we have a VPN tunnel.
I'm not sure of the exact costs. I didn't purchase it, I just use it.
Which other solutions did I evaluate?
I've compared the solution to Palo Alto and Cisco.
What other advice do I have?
Right now, more and more services are moving to the cloud. In terms of the cloud, the IP address changes so frequently. Today you see this IP for this service, the next day, without notifications, they may change IP to other IP addresses. So, originally, all firewall rules were based on the IP address. Now, it's not based on the IP address; it's based on the service. I can see Fortinet has already worked on this. For example, they provide internet service, which I remember, even though I haven't tried it yet. There's an internet service called Office 365. You just use this; you don't need to know the exact IP address or something; you just use this name. In the background, Fortinet updates this, updates all the information about this group, so you don't need to. The firewall keeps retrieving all that information from Fortinet, so you don't have to worry about the frequent change on the cloud side.
So far, I'm very satisfied with this device. Compared with other vendors, like Palo Alto and Cisco, I'm delighted with FortiGate, to be honest.
I'd rate it ten out of ten.
