Firewalls: Firewalls are extremely useful when it comes to protecting your computer and network from outside attacks from malicious or unnecessary network traffic. It also blocks malicious software from accessing your network. Firewalls can also be configured to block data from various locations or applications while at the same time allowing whitelisted data through.

Hardware firewalls, also known as network firewalls are external devices that you physically place your computer and your modem, router, or other network connection. Many internet service providers offer routers with this type of security already built in. This type of firewall is especially useful if you are in the market to protect multiple computers at once and control the various types of activity that pass through them. The biggest advantage of this type of firewall is that it is a completely separate device which means it has its own operating system that the malware would need to crack before it can move on to your primary system.
One of the biggest benefits of software firewalls, on the other hand, is the fact that practically every operating system you can name includes a firewall feature that can be enabled, for free. As such, even if you install a physical firewall you will still want to configure your software firewall as well. Software firewalls are also useful in that they have the ability to control the access that individual processes on the computer have to the network. While running a software firewall is better than nothing, it is important to keep in mind the inherent limitations that come about when the firewall tries to enforce protections on a system that it is a part of. This is going to be doubly true if you are installing a new software firewall onto a system that is already compromised.
