Many businesses today have the need to communicate across multiple sites and there are many different mediums available to accomplish this with varying levels of cost.
By far the cheapest solution is a Virtual Private Network, this method makes use of cheap internet connections to securely transmit data or voice. Devices at each end of the link are responsible for encrypting and decrypting the traffic that needs to traverse the VPN, thus ensuring that the information is not viewable by line sniffers.
VPN's are also commonly used for remote workers or "tele workers" Members of staff that require access to the corporate email system or applications can do so in a secure manner using a "client" vpn whilst on the move.
Other methods of communication include ISDN, leased lines, long range ethernet and microwave links too name but a few.
