The Internet is a great finding for the human kind, no doubt of that: we can shop online, socialize, communicate, sell stuff and so much more.
A less known aspect related to everything we call communication (the Internet it is also a communication system – between computers, of course) is… security.
Usually we protect our PC by installing an antivirus, anti-spyware etc, but did you know that another great for of protection comes from firewalls?
There are many ways a firewall can protect the data you are sending out or receiving, and there are tons of businesses offering various related services. I am a huge fan of Sonicwall firewall, they offer a wide range of products at fair prices.
So, you have a network and could use some protection? Check out http://www.sonicwall-sales.com.
