What is VPN?
A VPN (Virtual Private Network) is a network technology that creates a secure network connection between individual users/remote offices and their organization’s network over both private networks as well as public networks like the Internet. VPN establishes a secure Internet connection between individual computer and main network. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network.
An Internet VPN solution works as follow:
- A remote user log into Internet.
- Next, the user initiates a VPN connection to the company VPN server. This connection is made via a VPN client installed on the remote host.
- Once the connection has been established, the remote user can communicate with the internal company systems over the Internet just as if it were a local host.

Using a method called tunneling, VPN establish private connections through Internet. In order to gain access to the private network, remote user must be authenticated using unique identification key and password. [Read more…]
