A Virtual Private Network (VPN) provides an encrypted tunnel to connect to networks. It can be used to securely connect from a home office to a corporate network or as an additional layer of security when using public wireless networks (e.g. the free WiFi at a coffee shop).
The term virtual private network (abbreviated VPN) describes any technology that can encapsulate and transmit network data, typically Internet Protocol data, over another network Such a system enables users to access network resources that may otherwise be inaccessible from the public internet VPNs are frequently used in the information technology sector to provide access to resources for users that are not physically connected to an organisation's network, such as telecommuting workers VPNs are so named because they may be used to provide virtual (as opposed to physical) access to a private network Colloquially, the term VPN may be used to refer, albeit improperly, to a proxy service that uses VPN technology (such as OpenVPN) as opposed to higher-level proxy server protocols (such as SOCKS) as it does not require configuration of individual applications to tunnel their traffic through the proxy server, instead employing routing to redirect traffic
