Privacy and security come at a price. Steven J. Vaughan-Nichols on the industry’s latest buzzword: VPN.
A VPN uses encryption technologies, such as IP security (IPSec), Layer 2 Tunneling Protocol (L2TP)/IPSec, and Secure Sockets Layer (SSL) and Transport Layer Security (TLS), to create a virtual encrypted “tunnel” between your device and a VPN server. While your traffic is in this tunnel between you and a VPN server, no one can see where you’re going or what you’re doing.
Which means your online profile is not easy to track.
