The basic idea behind a VPN is a secure, private connection that travels over a public network. VPN stands for Virtual Private Network, which highlights two things: it’s not a physical separate network (virtual) and it’s a private, secure connection (private). Its main function is to create an encrypted tunnel between your device and a VPN server or gateway, so data stays confidential and protected from tampering as it moves across networks like the internet. This lets you securely access a private network remotely—for example, a coworker connecting to their company’s internal resources—or simply browse with greater privacy by routing traffic through the VPN server. Encryption and tunneling protocols such as IPSec, OpenVPN, TLS, or WireGuard make this protection possible. The other options don’t match the standard terminology or convey the privacy aspect that the acronym represents.
