A VPN on an iPhone stands for Virtual Private Network, which encrypts your online traffic and hides your IP address. It routes your traffic via remote VPN servers, so neither your internet provider nor other third parties can intercept and snoop your traffic and sensitive data. This adds an extra layer of privacy when you connect to the internet. A VPN connection secures your online traffic and data against eavesdropping, constant ad-tracking, Wi-Fi spoofing, and cybercriminals, especially when you’re connected to public Wi-Fi networks. VPNs can also help protect sensitive data such as personal details, bank accounts, and credit card information. VPNs can be configured manually by adding remote server info, or through a mobile device management (MDM) solution. VPNs are not in-built free VPNs, and they are services that you would need to pay for.
