The acronym "VPN" stands for Virtual Private Network. In the context of internet security, a VPN provides a secure and encrypted connection over a less secure network, such as the internet. It enables users to send and receive data as if their devices were directly connected to a private network, protecting sensitive information from interception. VPNs are commonly used for remote work, ensuring privacy and anonymity online while allowing access to restricted content or organizational resources without exposing the user's actual location.
