I have used some software-based solution, but it was not effective that much. I've downloaded Check Point. I've already checked on SonicWall.

The previous solution was not effective enough. First of all, the stability, which is great. And then the manageability is quite easy for this. So that's why I switched to FortiOS.

I have previous experience with Palo Alto and Juniper. We also have used Cisco.

I didn't choose Fortinet. It was already being used when I came along. It was a standard practice to use Fortinet across locations worldwide. 

Previously, we were mainly using Cisco firewalls and products.

There was something else that was used. However, I don't remember what was that previously.

I've had previous experience with Cisco products.

I work with Palo Alto, Cisco, Fortinet, et cetera.

We are using Fortinet, however, we are exploring Palo Alto.

We've also used SonicWall. 

I worked on FortiGate and Palo Alto.

Our company has always used the solution and is not interested in other products. 

We are tied to Fortinet and therefore did not use any other product.

We've used other solutions in the past. But we've settled into FortiGate for around 10 years. 

We were using Juniper before we choose Fortinet FortiOS.

I've also worked with Check Point. 

We were previously using other firewalls, such as Palo Alto. They are similar solutions.

I have used other solutions, such as SonicWall. I have found SonicWall's GUI to be less complicated than Fortinet FortiOS.

We ended up choosing the solution because of its ease of use and it troubleshooting steps were easy to control.

Previously, I used Cisco ASA Firewall.

We had been using Check Point and we still use it. In fact, we have been working with Check Point more than Fortinet. I may be a bit biased toward Check Point because I already have more implementation support for it than FortiOS.  

The difference between the price of the products is also obvious. Pricing is more flexible with Check Point than with Fortinet. Fortinet ends up being more expensive because of the pricing scheme.  

The pros and cons of them are not so much different. If it were my choice and we were going to change what we use or choose between the two, then we would move back to using Check Point exclusively. 

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.

I can only compare it with SonicWall, and it is missing many advanced features that SonicWall has. SonicWall has multiple advanced features on the DNS, Antivirus, etc...  and a lot of options that don't exist in Fortinet.

With SonicWall, I never had to use the CLI but have had to with Fortinet. They are missing many things on the interface.

FortiGate is like a teenager, where SonicWall is the adult firewall. However, it is more robust than SonicWall, particularly on the VPN site to site and SLL Inspection.

I have had experience working with Check Point UTM. These products have the same features. However, the user interface and support for Fortinet are superior to Check Point.

We switched to Fortinet because it's easy to use and deploy. In recent years, Fortinet has worked to combine the SD-WAN and next-gen firewall into one device, improving the ease of use. 

I used Palo Alto NG Firewalls before but I wasn't impressed by the features it offer and the  price was also too high.

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.

We have an array of products that are specific to our environments, and the requirements around the service needed for that specific environment, FortiOs ticked the boxes to the best match for our requirement.

We mostly focus on Fortinet products for our firewalls. We don't really use a different solution and haven't used something else in the past. I'm familiar with Sophos firewalls but have not deployed any just yet.

While Sophos is more expensive than Fortinet, from what I have seen, their functionality is basically the same. The difference between the two appears to be simply in the architecture of each solution. They are quite similar, but the user interface is a bit different.
