Virtual Private Networks (VPNs) have become one of the cornerstones of secure communications over the internet. VPNs encapsulate data and encrypt the data using an algorithm contained within the transmission protocol. VPN traffic is encrypted and decrypted at the transmission and receiving ends of the connection.
