What is a VPN?

At a glance: Software that provides an encrypted connection to keep you hidden.

The term ‘VPN’ stands for Virtual Private Network. A VPN lets you connect to the internet while at the same time stopping third parties (snoopers or your ISP) from seeing which websites you use. It acts as a shield, encrypting data that passes between your phone or PC and the internet.

When using a VPN to browse the web or stream TV shows, you’ll remain anonymous as the software will assign you a custom IP address instead of your usual one. Websites will log that temporary IP address when you visit them.

VPNs are massively popular for one key reason – they let you visit websites that are blocked in your home country. By connecting to a VPN server in another country, you can trick a website into thinking you’re a resident. A person based in Thailand could connect to a UK VPN server and unlock BBC iPlayer, for example.

Have a look at the screenshot above. Here, we’ve opened up ExpressVPN while in the UK and connected to a server based in New York. This means that, when we log into our Netflix account, we’ll have access to a content library usually reserved for a US audience. It’s easy to swap servers if there’s an issue, too.

How does a VPN work?

At a glance: A VPN assigns you with a custom IP address to disguise your location.

When you load up your VPN and connect to a server, the software acts as a go-between. As you use online services, your browser requests are sent from the VPN server on your behalf.

Your original IP address is automatically replaced with the VPN server’s IP address. Websites and online platforms see the VPN server’s IP, effectively hiding your true identity.

To demonstrate, have a look at the screenshot above. Although we’re based in the UK, we’ve used ExpressVPN to assign us an American IP address (above, right). That means that, when we visit What Is My IP Address (above, left), the website thinks we’re in New York.

Are VPNs expensive?

At a glance: Our recommended providers typically cost between £2-6 per month.

Research shows that you can get a solid VPN at a fairly affordable price. There are lots of providers to choose from and prices change regularly as they battle against each other for your attention – deals around Christmas are common, for example.

To make sure you get good value for money, we suggest shopping around for a VPN that meets your needs. You won’t struggle to find a server that costs less than £5 a month if you’re on a tight budget.
