The rest of this site judges 77 providers. This section explains the thing being judged: what a VPN does, what it cannot do, and which of the promises made for it are true. It is written for a reader who has not decided they want one.
Everyone who carries your traffic can read where it goes.Visibility moved rather than disappeared: the party in the middle changed.
Public Wi-Fi is less dangerous than the advertising says, because HTTPS already seals most of what you send. A VPN still hides which sites you reach, and some real risks remain that it does nothing about.
A DNS leak happens when your VPN carries your traffic but the name lookups go around it, which shows your network the sites you visit. This page covers why that happens and how to check for it.
A kill switch stops your traffic when the VPN tunnel drops, so it cannot carry on unprotected without your noticing. Kill switches differ in what they cover, and the differences decide when one actually helps.
"Independently audited" can describe very different pieces of work. This page covers the kinds of audit, what each one can show, and the questions to ask before an audit changes your mind about a provider.
Both make a request from another address. A VPN normally carries all your device's traffic and encrypts it; a proxy usually handles one app and may encrypt nothing at all. Here is how to tell which one you have.
Many people do not. A VPN solves a few specific problems well and does nothing for the rest, so the answer depends on which problem you have. This page goes through the common ones.
A VPN asks you to trust one company. Tor splits your connection across three relays so that no single one sees both who you are and where you are going. They solve different problems, and neither replaces the other.
What happens to a packet between your device and a website when a VPN is on: the handshake, the tunnel, the name lookup and the exit. Each step also explains one way a VPN can fail.
In most of the world, using a VPN is legal. A short list of countries restricts, licenses or blocks them, and what you do through one is a separate question everywhere. This page is a map of that, not legal advice.
Running a VPN costs money every month, so a free one is paid for by something. This page sets out what that usually is, what has gone wrong in practice, and how to tell a sample from a business model.
A VPN protects one stretch of the path: your device to its server. This page covers everything outside that stretch, from your browser and your accounts to malware, a dropped tunnel and the claims made in the advertising.
One encrypted hop between your device and the internet. This page is the starting point for the section: what the hop does, who it hides you from, who it hands the view to instead, and which of the promises made for it survive contact with the mechanism.
A guide is steps — open this, change that, confirm it worked. An explainer is prose about a mechanism: it answers what a thing is and what it does, not how to operate one. If you came for the settings rather than the subject, the guides are where they are.
Same rule as the guides. Where an explainer names a provider it links to that provider's record, not to a tracked outbound link — a page written to explain something is the worst possible place to sell it.
