Understand VPNs, choose one on evidence, or build your own

Fast VPN Services is an independent knowledge base about virtual private networks and everyday online privacy. Providers are bought at retail with our own money, tested on our own hardware, and written up with the method and the raw numbers attached. Nothing here is sponsored and nothing is for sale.

Start here

• VPN basics — what a tunnel actually does, which protocol to use, and the claims that should make you close the tab.
• Choosing a provider — a twenty-minute evidence check covering ownership, audits, logging and jurisdiction.
• Test what you already have — DNS, IPv6 and WebRTC leak testing, because a connected VPN can still leak every domain you visit.
• Run your own — a complete WireGuard build on a five-dollar VPS, including the parts other tutorials skip.

The one thing worth knowing first

A VPN does not remove trust from the equation. It moves it from your internet provider to a company you have never met. Everything on this site is about deciding who deserves that trust — or replacing them with a server you control.
