Introduction
The concepts and terminology you will meet throughout the VPNGeek apps and this documentation.
What a VPN does for you
A VPN builds an encrypted tunnel between your device and a VPNGeek server. Everything you send travels inside that tunnel, so the networks in between — a café hotspot, your ISP, a mobile carrier — see only encrypted traffic to a single endpoint, not the sites and services you actually reach.
Key terms
- Server — a VPNGeek endpoint you connect through. Picking one in another country changes the apparent origin of your traffic.
- Protocol — how the tunnel is built. VPNGeek uses WireGuard by default and offers OpenVPN and IKEv2 where you need them.
- No-logs — we do not record what you do inside the tunnel. This is enforced by design and independently audited.
- Kill switch — blocks all traffic if the tunnel drops, so nothing leaks in the gap.
What VPNGeek does not do
A VPN is one layer, not a whole security posture. It protects data in transit and hides your traffic from the local network, but it does not replace good passwords, device updates, or common sense about what you click. Treat it as the encrypted foundation the rest of your habits sit on.
