WebA virtual private network ( VPN) is a network that is established on top of existing networks to establish a secure communications method for data and IP information exchanged across networks. IPsec is the Internet Engineering Task Force (IETF) standard VPN technology for the TCP/IP suite. In contrast to compact VPNs, IPsec is large and complex. In computing, Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network.
