VPN Basics: What a VPN Does and Whether It's Safe

Plain-English answers to what a VPN is, whether you need one, whether VPNs and free VPNs are safe, and what all the jargon means

New to VPNs? These guides explain the basics without the jargon: what a VPN actually does, whether you need one, and how to tell a trustworthy provider from one that might sell your data.

If a word in any of our guides doesn't make sense, the glossary explains it in a sentence or two. And if you want to know how we pick the VPNs we recommend, our selection guide explains what we look at and why.

The Best VPNs for Privacy and Safety

If the fixes above didn’t work, the problem is usually the VPN itself. Not all providers are equal at unblocking streaming services. These are the ones we recommend, based on their streaming track record, features and value.

The “Try” buttons for NordVPN, ExpressVPN and PureVPN are affiliate links: we earn a commission if you subscribe, at no extra cost to you. Full disclosure.

#1
NordVPNStarting from £2.59/mo

Widely rated among the most consistent VPNs for BBC iPlayer, Netflix, Disney+, and the harder UK services. Reliable, fast, and works on up to ten devices at once.

Try NordVPN
#2
ExpressVPNStarting from £2.19/mo

Consistently among the fastest in independent speed tests, and competitively priced. A strong choice if speed, picture quality, or smart TV streaming matters to you.

Try ExpressVPN
#3
PureVPNStarting from $2.15/mo

The most affordable of our three picks. Still unblocks all the major streaming services, and the price makes it a sensible starting point if you're new to VPNs.
