The Best pfSense Hardware you can buy in 2021

In home and enterprise networking, pfSense, which is owned by Netgate, happens to have a huge fanbase due to its wide variety of features, considering its zero cost price point and continuous development as an Open Source firewall. To address the issue of hardware, pfSense boxes are among the appliances that you may require to give a shot. So, the best pfSense hardware in 2021 ultimately depends on the amount of load that you intend to place on the box.

But let us drop the bombshell, there is not much to consider since most of the compatible hardware will give you good value for your money, the important part is, it has two or more NICs (Network Interfaces). I would also suggest buying Netgate products just to support the project, they tend to have the best support.

After spending some time with the developers on my pfSense Expert Certification Course, I can assure you your money is well invested.

Now, let's have a quick rundown on all the most popular pfSense appliances.

1 - Firewall Micro appliance with 2x Gigabit Intel Ports

This Firewall Micro Appliance from Protectli is fanless, hence it produces no operational noise and was designed as a firewall router with a simple mission. That is to be low cost and a cross-compatible. For this FW20001 barebone, it lacks both the RAM and mSata storage just to leave an open door for users to choose on what suits their need.

  • Support for one SSD mSata

2 - Firewall Micro Appliance With 4x Gigabit Intel ports

Underlisted appliance is sort of an advancement to the 2x ports appliance in parameters such as cost, specification, and features. The updated version of this unit is also from the same brand, Protectli, with tested compatibility on pfSense, OPNsense, and other open-source firewall solutions. A good bit, among the best pfSense hardware in 2021 it also seems to surmount higher loads of up to 18 Watts.

3 - The Netgate SG-1000 Micro Firewall

Netgate SG-1000 ships with pfSense pre-installed, albeit it appears to be out of stock for what you would equate to a case of demand.

4 - Firewall Micro Appliance With 6x Gigabit Intel Ports

With 6x Gigabit Lan Ports, this Firewall Micro Appliance is arguably a premium version from Protectli coming with a striking appearance adjoined with funny baseboard. It is a beast for things like load balancing, running moderately at 20W and maximally at 30 W. Comparing it to other appliances, it retails high as advertised by a consortium of vendors but it is definitely worth the dime.

  • Runs up to 30 W loads in maximum

5 - Firewall Micro Appliance with 6x Intel ports, i5 7200U

For this solid-state appliance, there seems to be a feature hiatus since Protectli sells it without RAM or mSata memory storage. The seller, however, considers this as a plus for the buyer to expand the duo to their size of choice. Having been purposely built as a firewall router, the aforementioned Intel i5 7200U Firewall Micro appliance has a tested compatibility in working efficiently with open source firewall projects thus giving you a budget pat.
