A virtual private network (VPN) application for Apple’s mobile operating system, offered without direct monetary cost, provides a layer of encrypted connection between a user’s device and the internet. An example of its use is when a person utilizes a public Wi-Fi network; the VPN aims to protect data transmitted, potentially shielding it from interception.
The perceived value of these applications centers on augmenting online privacy and security on iOS devices. Historically, concerns over data security and surveillance have driven the demand for methods to obscure online activity. A no-cost access point can broaden adoption, allowing more users to potentially benefit from such protective measures, particularly where cost is a barrier.
