What is a VPN? A practical guide to what it actually does
Understand encrypted tunnels, IP addresses, provider trust, and the limits of a VPN before you choose one.
A curated reading path
Online privacy: look beyond one connection
Read about provider trust, public Wi-Fi, DNS behavior, account identity, and the boundaries of VPN protection.
Build a useful understanding.
Network routing is one part of online privacy, not the whole subject. A tunnel does not remove an identifying login, decide which website you intended to visit, or control information you voluntarily submit. This reading path helps you connect VPN decisions to those wider questions without assuming a single product can answer all of them.
Browse the fundamentals to understand the tunnel boundary, the provider-selection guide to examine trust, and the public Wi-Fi guide for a measured look at everyday connections. The DNS and kill-switch articles address narrower situations where the intended route and the observed route can differ. Their checks are useful precisely because they explain the limits of what a result establishes.
Use the privacy hub alongside these articles to organize your own priorities. Write down the information you care about, who you are concerned may observe it, and which action addresses that particular concern. A small number of understood controls is easier to maintain than a complicated setup chosen from broad promises.
