I am researching firewalls and found the following two options: Fortinet FortiGate and pfSense.
What are the differences between these two firewalls? Which firewall do you prefer and why?
Thank you for your help.
Especially with support and updates of the signatures, FortiGate has a more solid base. Being an IPO company, with respect to Pfsense, start as a community project and you can purchase support and even dedicated appliances if you have a budget for FortiGate, or if you are starting Pfsense.
Both are very good products, but some features that Sophos mentioned as new, FortiGate has been handling. If you are going to grow with several appliances I recommend Sophos, since the administration can be done from the cloud. With Fortinet, you have to pay a licensing fee. In terms of costs and all the options, they are very similar. Another detail to review is the support, at the beginning with Fortigate, I had enough details, but it is really improving significantly with respect to Sophos.
My comment is based on experience and I do not lean toward any of the brands. To reiterate, they are good types of equipment.
Basically, the main difference is that the TZ series is intended for a Branch office since it has fewer ports and the speed is around 1 GB.
The NSA series has more processor power and more port where you can create subnets and zones (like DMZ). Also, it has ports with 10 Gb and a processor to support the demand.
I have read that an approximate number of users in the highest TZ series (TZ 670) is around 150 to 200 but that is just an estimate.
Hope this helps. You can get more details in SonicWall datasheets where you will find the speed, throughput and more technical specifications to select the one that fits your requirements.
