VPN stands for “Virtual private Network”. A VPN is a secure, private communication tunnel between `two or more devices across a public network (like the Internet). These VPN devices can be either a computer running VPN software or a special device like a VPN enabled router. It allows your home computer to be connected to your office network, or visit a web server, or can allow two home computers in different locations to connect to each over the Internet.
Allows you to be at home and access your company’s computers in the same way as if you were sitting at work.
Almost impossible for someone to tap or interfer with data in the VPN tunnel.
If you have VPN client software on a laptop, you can connect to your company from anywhere in the world.
As more and more websites blocked by country, company or school firewalls, VPN is a good solution to access blocked websites security. VPN gives extremely secure connections between private networks linked through the Internet. It allows remote computers to act as though they were on the same secure, local network.
