A small icon changes, the connection says <em>protected</em>, and the Internet keeps working.</p> <p>What actually changed?</p> <p>Your laptop did not leave the airport network. It created a protected path <em>through</em> that network to another system: a VPN gateway. Selected traffic now travels inside that path before continuing toward a company network or the public Internet.</p> <p>That is the shortest useful definition of a <strong>virtual private network (VPN)</strong>: a VPN uses a shared network, usually the Internet, to carry traffic between authenticated endpoints as though they had a private connection. The path is virtual because it is built in software rather than as a dedicated physical circuit. It is private because cryptography protects traffic while it crosses the untrusted part of the route.</p>
