A great way to stop these online threats from getting into your network and devices is to use a Firewall.

Protectli Vault FW4B is a four-port Mini PC bundled with a 64-bit Intel J3160 processor. It is available in many RAM and storage variants.

The one I am mentioning here has 8 GB RAM and 120 GB SSD storage. You can also go with the barebone (no RAM, no SSD) version where you have to add the RAM and SSD yourself to complete the build.

Unlike other hardware firewalls on this list, Protectli Vault FW4B doesn’t come pre-loaded with any firewall software. You have to manually install a firewall solution. It is compatible and tested with many open-source solutions including pfSense, OPNsense and Untangle.

This gives you a lot of flexibility in choosing your firewall software and creating a customized security system that is tailored to your needs. Moreover, it has a fanless design which makes it completely silent during operations.

If you’re not afraid to get your hands dirty and want to build a security system yourself, then Protectli Vault FW4B will be a perfect choice.

The specs of Vault FW4C are almost similar to its predecessor (Vault FW4B). The major difference is – a faster CPU and the four Intel 2.5 Gigabit Ethernet Ports. The 2.5GbE is 2.5 times faster than the standard 1GbE that you get in the Protectli Vault FW4B.

Again, this Mini PC doesn’t ship with any pre-installed firewall solution. You need to manually install firewall software such as pfSense or OPNsense.

If you have devices that can utilise the 2.5 GbE, then Protectli Vault FW4C will be a great choice as a hardware firewall for your home.

Home Hardware Firewall Buying Guide

Here are some things to consider when looking for a hardware firewall:


One of the most important things to consider in a hardware firewall is the throughput. If you didn’t get this one right, then you’ll have to suffer the slow speeds.

It all depends on how many users will be on the network. Usually, for home needs, 500 Mbps throughput is enough. If the number of users is more, then you may want a hardware firewall that can handle 1Gbps throughput.

Therefore, it is recommended to get a rough idea of how many devices are you planning to connect and their use cases before purchasing the hardware firewall, so you don’t have to compromise on speed.

Device Monitoring

Another thing to look for is the Device monitoring feature. With this, you’ll be able to keep an eye on all the devices that are connected based on the name and not just the IP address.


Last but not least is pricing. Hardware firewalls can range from hundreds of dollars to even thousands of dollars depending on the level of protection it will provide. Most of the high-end firewalls are for large businesses.

You don’t have to spend a fortune to get a firewall for your home. With Open-source firewall solutions such as pfSense and OPNsense, you can even turn old hardware with a compatible network card into a hardware firewall.


This concludes the best hardware firewall for home list. I have also made lists of pfSense hardware and OPNsense hardware. You can check those out if you want a device that is compatible with the two most popular open-source firewall solutions.
