Easy to use with a powerful CLI and a nice graphical user interface
Pros and Cons
  • "The technical support on offer has always been quite good."
  • "The solution is very easy to use, has a powerful CLI and a very powerful graphical user interface, scales well, is reliable in terms of stability, is not too hard to implement, and technical support is helpful and responsive."
  • "The pricing of the product is too high. They should work to lower it."

What is our primary use case?

Fortinet is used for security. FortiOS is the operating system. FortiAnalyzer, for example, can be used on it and it is used for log management, et cetera.

What is most valuable?

The solution is very easy to use. It's a solution that has a powerful CLI and a very powerful graphical user interface.

The solution scales well.

In terms of stability, the solution is reliable.

It's not too hard to implement the solution.

Technical support is helpful and responsive. 

What needs improvement?

The pricing of the product is too high. They should work to lower it.

For how long have I used the solution?

I've been using this solution for three years. It's been a while. 

What do I think about the stability of the solution?

The solution is stable. There are no bugs or glitches. It doesn't crash or freeze. The performance is reliable 

What do I think about the scalability of the solution?

We have found the product to be scalable. It's not a problem if you want to expand it.

There are 1,000 users on the solution at this time. 

While there may be plans to increase usage in the future, I'm not sure if that's the case just yet. 

How are customer service and support?

The technical support on offer has always been quite good. We are satisfied with the level of service they provide.

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

Previously, we were mainly using Cisco firewalls and products.

How was the initial setup?

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.

What about the implementation team?

We used an integrator to help us deploy the solution.

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

The solution is fairly expensive. The cost is around $40,000.

It would be ideal if they offered more licensing options.

Which other solutions did I evaluate?

We were presented with some other solutions such as Palo Alto and Check Point. We prefer Fortinet due to the features on offer.

What other advice do I have?

I'm an end-user and customer. 

We are using a few versions of the solution, some with 6.2, which is not the most updated version, and some others with almost legacy versions such as 5.6.

I would advise users to not stick with the last version if a new release comes out.

I would rate the solution at a nine out of ten. We have been largely pleased with its capabilities. 

Which deployment model are you using for this solution?

A seamless endpoint gateway solution with constant updates and a zero choice engine
Pros and Cons
  • "The most valuable features of Fortinet FortiOS are its constant updates and definitions."
  • "I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle."

What is our primary use case?

We use it for end-point gateway protection and also use the FortiOS for external user connection and server VPN. We love that clear synchronization as it's almost invisible with the fabric for the guests, externally to connect. The zero-choice engine that they use is pretty good. It is perfect for setting up one-to-one channels for different services that have to pass through the firewall. So it does that seamlessly.

What is most valuable?

The most valuable features of Fortinet FortiOS are its constant updates and definitions. The new definitions and the content information coming out to the threat labs keeps you updated on your signatures so that you know what's happening out there. And also doing well, for my system, we have, like, what is called, active scans.

It's constantly accessing Sophos into your gateway, even Sophos that you authorized.

What needs improvement?

I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle. I want to see if that enhances a bit more so I have granular datasets and the user level through to the gateway because that's where most of our threats come from. It's from user activities on the Internet and passes into your files over that gateway. That's where most of our threats would appear and where our exposure to vulnerabilities lies.

So if we can tighten that up, we can harden our infrastructure much better.

For how long have I used the solution?

I have been using the solution for quite some time.

How are customer service and support?

The customer support team is good and responsive.

How was the initial setup?

We did the initial setup ourselves, so it was easy. The learning curve was that great once you have any experience with any firewall or any experience with any security appliance, you can pull around it. We did get some help from our providers. But that was basic.

What about the implementation team?

The EMS setup was all in-house. Our service provider assisted with the firewall setup. The implementations were very smooth. And the transition of our current from our current security device to that when we did it a couple of years ago, it's seamless.

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

The pricing is competitive for the medium and high markets but for the small markets it can be expensive.

What other advice do I have?

You have to see what works best for your environment. Each environment is different depending on the applications and different services you are running in that environment. Suppose it's a full Windows environment versus a mixture if you have a hybrid environment. It all depends on the type of environment you're running and finding the right tools that meet your domain.

But for the regular Windows environment, it's perfect.

I rate it eight out of ten.

The security on offer is good.

It's quite stable.

The scalability has been great.

We found the initial setup to be straightforward. 

Technical support has been good overall. 

What needs improvement?

The UI could be a bit better. The coming generation will not be from the Sierra, and therefore they have a chance to make it much better and more user-friendly. Right now, we have to contend with CLI. We'd like it to be easier. We need the features to be in a UI.

For how long have I used the solution?

I've been using the solution for more than five years.

Positive

How was the initial setup?

It offers a pretty simple and straightforward setup. I'd rate it four out of five in terms of ease of implementation. It's not something that's too complex or difficult. 

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

I don't have many details surrounding the licensing. It's not an aspect I directly deal with. My understanding is the solution is moderately priced.

What other advice do I have?

We are Fortinet partners. 

If a company is looking for a local security enhancement, we tend to recommend or select this kind of solution.

Valuable inbuilt SD-WAN useful for firewalls and the efficient fulfillment of orders
Pros and Cons
  • "The initial setup is straightforward, and it is very customer friendly."
  • "Fortinet FortiOS quickly provides many complex solutions when we deploy a simple firewall, so it's named one of the most customer-friendly OSs in the industry in Sri Lanka and globally."
  • "The solution is good but could be improved by supporting an allocation of quota base management regarding user data."

What is our primary use case?

Our primary use case for this solution is for firewalls and the efficient fulfillment of orders. Additionally, with Fortinet FortiOS, you get other features like inbuilt SD-WAN, where the customers are ready to deploy once they move into the SD-WAN features. So there are several additional features within the OS and integration with third-party software, other vendors and third-party solutions. So the integrability, adaptability, and value addition of the OS play a significant role.

What is most valuable?

We have found the inbuilt SD-WAN most valuable. For example, with FortiGates, we refer to it as being SD-WAN-ready because the customer has to buy it in the box, and the OS supports it by building a connection between two units. Also, regarding the OS integrability with other third parties, for example, with Ciga Group, you can deploy a unit in Sri Lanka, and the customer may have another unit in a different geography. Within Fortinet FortiOS and other competitive products, it's integrative, so it's used for data flexibility.

What needs improvement?

The solution is good but could be improved by supporting an allocation of quota base management regarding user data.

For how long have I used the solution?

We have been using this solution for three years.

How are customer service and support?

I rate customer service and support a ten out of ten.

How was the initial setup?

The initial setup is straightforward, and it is very customer friendly. Fortinet FortiOS quickly provides many complex solutions when we deploy a simple firewall. So it's named one of the most customer-friendly OSs in the industry in Sri Lanka and globally. Therefore, customizability allows you to deploy the boxes and register a serial number. Eight people on our technical team are involved in deployment. I rate the initial setup process as nine out of ten.

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

I cannot comment on licensing costs as a different department handles that.

What other advice do I have?

I rate this solution a nine out of ten.

Flexible, easy to use, and meets our requirements
Pros and Cons
  • "It's easy to use."
  • "So far, I'm very satisfied with this device."
  • "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.
