What is a VPN?

VPN stands for Virtual Private Network and, as its name suggests, is a way of creating a more private connection to the internet.

VPNs act like a network within a network by adding a virtual layer to your physical network connection. This layer creates a special tunnel to connect a client (such as your Mac or phone) to a server (the remote location). All data sent between server and client is encrypted, so it can’t be read by another party.

There are two main uses for VPN, which determine the type of server being used. The first type is a consumer VPN, which is used to provide a more secure and private connection to the internet, regardless of the security of the network you’re connecting through. It means you can safely browse over unsafe networks such as public Wi-Fi hotspots. This option involves signing up with a VPN provider, then connecting to the internet through one of its many servers situated around the world. Both free and paid-for options are available, offering different types of service, performance and levels of privacy.

The other type is a corporate VPN. Here, the server is hosted on a specific network, such as the one at your workplace or home. This allows you to dial in securely to that network and access it as if you were physically on site. This type of connection basically extends the internal network out over the internet, so you can access shared resources, including an intranet, printers and storage.
