How does VPN work?

A VPN, or Virtual Private Network, allows users to securely access a private network across a public network i.e the Internet. A VPN enables users to send and receive information/data across both shared, and public networks as if the devices exchanging the information were connected directly to a private network, or directly connected to one another. A Virtual Private Network is formed by establishing a virtual point to point connection through a ‘tunnel’; this ‘tunnel’ is encrypted by different protocols and creates a pipe where users can exchange information without hackers or snoopers being able to see, or access what is inside.
