Virtual private network ( VPN )
A virtual private network (VPN) turns an unsecured internet connection into your own private oasis. VPN is an essential technology for using the inherently insecure public Internet to provide secure data communication. It provides the benefits of expensive and secure private circuits using the low cost and flexibility of the public Internet. Once the tunnel is created. All the traffic will traverse the public Internet encrypted. Seamless routing rules can be created to provide "IP connectivity" between private subnets not having to worry about firewalls or NAT.
As a business grows, it might expand to multiple shops or offices across the country and around the world. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks. In addition, traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations.
One popular technology to accomplish these goals is a VPN (virtual private network). A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. The VPN uses "virtual" connections routed through the Internet from the business's private network to the remote site or employee. By using a VPN, businesses ensure security – not anyone intercepting the encrypted data can read it.
VPN was not the first technology to make remote connections. Several years ago, the most common way to connect computers between multiple offices was by using a leased line. Leased lines, such as ISDN (integrated services digital network, 128 Kbps), are private network connections that a telecommunications company could lease to its customers. Leased lines provided a company with a way to expand its private network beyond its immediate geographic area. These connections form a single wide-area network (WAN) for the business. Though leased lines are reliable and secure, the leases are expensive, with costs rising as the distance between offices increases
