A virtual private network (VPN) establishes a secure, encrypted connection over a less secure network. On an iPhone or iPad, this creates a private network from a public internet connection. For example, when accessing the internet via a public Wi-Fi hotspot in a caf, a VPN encrypts the data transmitted, making it unreadable to potential eavesdroppers.
The principal advantage lies in enhanced security and privacy. VPNs protect sensitive information, such as passwords, financial details, and browsing history, from being intercepted by malicious actors. Historically, VPNs were primarily used by businesses to allow employees to securely access internal networks remotely. Now, they are increasingly adopted by individuals seeking to bolster their online security and bypass geographical restrictions on content.
