Virtual private networks, or VPNs, were created with the aim of providing secure connectivity between multiple people and devices over public networks like the internet. By setting up a point-to-point tunnel, consisting of a secure encrypted link between the user’s device and the server of the VPN service provider, a VPN was seen as extending a private network over the public network. The main application of VPNs was seen to be the secure transfer of data, including corporate and financial data. The encryption and anonymity provided by the technology led to its adoption to protect data in transit across hybrid networks, protecting information from industrial espionage, government surveillance and criminals looking for valuable information that they can harvest and peddle. VPNs are of various types, depending on their topography, the security protocol that is used, or the tunnel’s termination points. One of the more popular VPNs is the Secure Sockets Layer VPN, which uses the SSL protocol and can be used from a browser without client software.
