A virtual private network (VPN) is a piece of software used to allows users a secure and private connection. This is achieved by creating a private network across a public internet connection.
Main Types of VPNs
Site to Site
A site to site VPN is when a single virtual network is created through multiple local networks.[1] This allows someone to access information from any local network connected to the virtual network while they are on one of the local networks. Once the user is no longer connected to any local network that makes up the virtual network, they are unable to access any of the data. This is due to the VPN Client being hosted on each network rather than a user's device.
Remote Access
A Remote Access VPN allows a user to connect to a remote server securely. [2] This is done by hosting a VPN client on the users device. By using a remote access VPN, an encrypted 'tunnel' is established.
Commercial VPNs
Commercial or consumer VPNs are based on the Remote Access VPN model. A commercial VPN uses a remote connection to have the VPN provider interact with websites on the user's behalf, rather than through the user's internet Service Provider. [3]
Uses
Access Remote Sites
Using a remote Access VPN, users from across the globe can access a singular private network. [4] This can be used by companies and individuals alike. At the University of Michigan, a VPN is used to allow students to access the Universities encrypted data when not on campus internet [5]. This allows students to work remotely on information stored at the university from their home, a conference, or a coffee shop. Throughout the Covid-19 Pandemic, Companies have relied on VPNs to grant employees access to servers, internal applications, and data hosted on site. [6] [1] These actions were taken to limit the exposure of sensitive data from being exposed online.
Privacy
As a VPN encrypts the data between the user and a server, a VPN Can help to keep a user's information private.[1]
Access Information From Other Countries
China's Great Firewall

Netflix

Ethical Concerns
Pirating of Payed Content
As VPNs can help to keep a user's web access a secrete from their ISP, VPNs are popular tools for torrenting copyrighted material.
