VPN (a virtual private network) is a service that encrypts your internet traffic on unsecured networks to protect your online identity, hide your IP address, and shield your online data from third parties. VPNs use real-time encryption and send user internet data through a secure VPN tunnel to minimize the possibility of anyone tracking what they do online.

How does a VPN work? When you connect to a VPN service, it authenticates your client (i.e., devices, such as a smartphone) with a VPN server and applies an encryption protocol to all your internet data. The VPN service creates an encrypted “tunnel,” securing the data traveling from your device. This encryption keeps your data safe, even on public Wi-Fi.
