What a VPN does (and doesn’t do)
A VPN (virtual private network) creates an encrypted connection, often called a tunnel, between your device and a server run by the VPN provider. Websites and apps see the VPN server’s IP address instead of yours, and your internet provider or the owner of a Wi‑Fi network can see that you’re connected to a VPN, but not which sites you visit.
A VPN is not a magic privacy shield. It doesn’t stop tracking cookies, logged-in accounts or browser fingerprinting, and it moves trust from your internet provider to the VPN provider. That’s why no-logs policies and independent audits matter so much. New to all this? Start with what is a VPN.
How to choose a VPN
- Privacy first: a clear no-logs policy that has been independently audited, and a company that is open about who owns it and where it is based.
- Security features: modern protocols such as WireGuard, a reliable kill switch and DNS leak protection. See VPN features explained.
- Your use case: streaming, travel, gaming or just safer public Wi‑Fi each favour different strengths.
- Your devices: apps for iPhone and Android, Windows and Mac, and routers, smart TVs and Fire TV, plus enough simultaneous connections for your household.
- Fair terms: the renewal price (not just the first-term discount), the refund window and how easy it is to cancel.

For VPN users in the US, UK and Europe
Using a VPN is legal in the US, the UK and EU countries, although breaking the law or a service’s terms through a VPN is not. Some countries restrict VPNs, so check before you travel: see is a VPN legal?
If you live in the EU, the EU’s portability rules let you use many of your paid streaming subscriptions while temporarily in another EU country, without a VPN. UK residents lost that right after Brexit, which is one reason UK travellers often ask about VPNs. Our streaming guide explains what’s allowed.
