If you are an internet user, you have heard of hackers and malwares. They are undesirable and dangerous for your security and privacy. Sometimes, you are being the victim of an attack and you might not even know it, but don't worry they are ways to protect your computer from these intrusions and infections. By example, you could use a personal hardware firewall, a simple device that can save you from a lot of pain.

First of all, let's define what a personal hardware firewall is. Actually, it is pretty simple; it is a device that is plugged between your modem and your computer or your network.

Its function is the same as a normal firewall that you would install as a software into your computer to protect yourself from intrusions, spams and pop-ups. You have to understand that a firewall doesn't act like a antivirus, its goal to block intrusions, not viruses.

Secondly, you might want to know how a hardware firewall works. It's simple, you plug it between your modem or your network and it will hide your computer for the internet with the NAT, Network Address Translation. It can also work with the NAT plus SPI, Stateful Packet Inspection.

The useful thing with the hardware firewall is that it can be used with a software firewall. The combination will help to prevent any kind of vulnerability into the network or the computer.So, if you are planning to install a very secure network in your home or just going to secure one computer, a hardware firewall might be one of your best options due to its simplicity, its efficiency and its low cost. But don't forget that the hardware firewall is not the ultimate security device, but is more like a masterpiece of a security system.

You might want to check out the Cisco eDelivery SSL Liscence. It is sold for 110$ and offers a great protection and can increase your number of distant connections from 2 to 25. If you are more the kind of customer who prefers industrial performance, than the ZyXEL ZyWALL 5 is for you, it is more performant, it offers only 10 distant connections, but gives you a iCard Silver filter to check out everything for maximum security, the only thing is that it costs about 350$. If you think that these two prices were to high for your needs, than the AlphaShield Hardware Firewall is perfect, it will protect against any type of hacking and information theft, all this for only 70$, which is more affordable than the Cisco eDelivery SSL Liscence.
