A virtual private network (VPN) is a tool that creates a secure, encrypted connection between your device and the internet. It hides your IP address, protects your personal data from hackers, internet providers, and surveillance, and gives you more privacy online.
Why use a vpn
- Privacy – stops tracking by your ISP, advertisers or government
- Security – protects your data on public Wi-Fi like in cafés or airports
- Access – bypasses geo-restrictions on sites like Netflix or BBC iPlayer
- Anonymity – changes your IP address to hide your real location
How a vpn works
When you turn on a VPN, your data is sent through an encrypted tunnel to a secure VPN server. That server then connects you to the internet. From the outside, it looks like you’re browsing from the VPN server’s location.
