Just What is a Virtual Private Network?
September 18, 2009
- The Way it Works
“The world has changed a lot in the last couple of decades. Instead of simply dealing with local or regional concerns, many businesses now have to think about global markets and logistics. Many companies have facilities spread out across the country or around the world, and there is one thing that all of them need: A way to maintain fast, secure and reliable communications wherever their offices are.
As the popularity of the Internet grew, businesses turned to it as a means of extending their own networks. First came intranets, which are password-protected sites designed for use only by company employees. Now, many companies are creating their own VPN (virtual private network) to accommodate their communications needs of remote employees and distant offices.
Basically, a VPN is a private network that uses a public network – usually a VoIP system to connect remote sites or users together. Instead of using a dedicated, real-world connection such as leased lines, a VPN uses “virtual” connection routed through the VoIP from the company’s private network to the remote site or employee.”
