Most of the broadband users have a built-in firewall, and generally, the hardware firewalls work by analyzing the information being sent over the networks. The information they receive from a computer or a particular network will not be delivered without the permission of a firewall. Nowadays, hardware firewalls have become very advanced, and they are suitable for home and small businesses.
