Personal firewalls

These are especially useful for users with always-on connections, like Digital Subscriber Line (DSL) or cable modem, because those connection types use static IP addresses. These attributes make a network especially vulnerable to potential hackers. As with all firewalls, the personal model's main function is to filter inbound and outbound traffic and to alert the user to intrusions. The difference is that it is for personal use and guards a single home network, as opposed to a large network with many potentially dispersed devices. It is often compared to antivirus applications.

Hardware firewalls
A firewall can either be software- or hardware-based. It is possible to have both and advisable to have both, depending on the user's needs. The benefit of having a physical firewall device is that it tends to be relatively tamper-proof because it needs to be accessed physically in order to do so. Also, because it is a dedicated network device, data passes through it quickly. It should not have a negative impact on network speed.
