Do I need a hardware or software-based firewall? Yes, everyone who uses the internet should have a firewall, whether it is software or hardware-based. Chances are, your browser has a software-based firewall, but it is definitely something to look into. If you use a broadband router then a firewall is generally built-in and therefore you will be covered. Routers are a good choice for a hardware-based firewall as they can be easily set up and do not interfere with your computer. It can’t hurt to have both a software and hardware-based firewall.
