The 7 Best Hardware Firewalls

This wiki has been updated 13 times since it was first published in December of 2018. As opposed to their software counterparts, hardware firewalls act as a physical gatekeeper between the web and your network and can catch suspicious traffic before it reaches your computer or phone. Additionally, they provide enhanced control, around-the-clock analysis of internet packets, and better throughput. These are some of the best for small businesses as well as advanced home users. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.

Editor's Notes

March 16, 2021:

Just to be clear, the vast majority of home users won't need one of these, because Windows Firewall does the job adequately for most people. Power users, remote workers, business owners, or IT professionals will often require the services of a good hardware firewall. With that in mind, the Zyxel USG Flex Series has something for just about everyone, up to offices that see about 150 people. The decent variety of variants and moderate price make it the best choice for many people. The WatchGuard Firebox T15 is a somewhat similar model meant for mid-sized business use, and it's also just about cost-effective, as is the SonicWall SOHO 250.

There are some instances where the average consumer will want a dedicated firewall, and there are good options. The Bitdefender Box 2 is the easiest to get running, likely because it's among the few specifically tailored to the home user experience. Alternatively, the Meraki Go GX20 offers the reliability of big name, at a remarkably low cost.

Finally, we want to point out the Awow AK34, which is actually an impressively low-priced Windows PC. While it's fully capable of running 64-bit Windows, with a little tech know-how, it can also be a more effective hardware firewall than many dedicated boxes.

January 10, 2019:

For the tinkerers out there, experts recommend building a homebrew firewall rather than using an off-the-shelf model when securing a network. Because proprietary router firmware can quickly go out of date, being able to install open source firmware, such as pfSense, on your firewall device provides more robust protection. The Protectli Firewall Micro, which is included in our list, allows for this type of customization.

Special Honors

Cisco Secure Firewall Cisco may be the most recognizable name in the networking game, and for good reason.

Their products do, generally, cost more than much of the competition, but you can be completely certain that you're getting a powerful and dependable piece of equipment. cisco.com
