Security > VPN

A Virtual Private Network (VPN) is a connection between two endpoints in different networks that allows private data to be sent securely over public networks or other private networks. This is accomplished by creating a "VPN tunnel." A VPN tunnel connects the two PCs or networks and allows data to be transmitted over the Internet as if it were on a private network. The VPN tunnel uses IPsec to encrypt the data sent between the two endpoints and encapsulate the data within a normal Ethernet/IP frame allowing the data to pass between networks securely and seamlessly.

A VPN provides a cost-effective and more secure alternative to using a private, dedicated, leased line for a private network. Using industry standard encryption and authentication techniques, an IPsec VPN creates a secure connection that operates as if you were directly connected to your local private network.

For example, a VPN allows users to sit at home and connect to his/her employer's corporate network and receive an IP address in their private network just as though they were sitting in their office connected to their corporate LAN.
