A VPN (virtual private network) encrypts your internet traffic and sends it through a server in another location.
What a VPN does
- Encrypts your connection, which matters most on public Wi-Fi.
- Hides your browsing from your local network and internet provider.
- Lets you appear to be in another country.
What a VPN doesn't do
- It doesn't make you anonymous to sites you log in to.
- It doesn't stop malware or phishing on its own.
- It can't fix a slow connection — it can make it slightly slower.
Who should use one
Frequent travellers, remote workers on shared networks, and anyone who values privacy online.
Choosing a VPN
Look for a no-logs policy, fast servers near you and support for all your devices. Compare options in our best VPN list.
