A virtual private network (VPN) extends a private network across a public network, such as the
Internet. It enables a computer to send and receive data across shared or public networks as if it
were directly connected to the private network, while benefitting from the functionality, security
and management policies of the private network. This is done by establishing a virtual
point-to-point connection through the use of dedicated connections, encryption, or a combination
of the two. The tunnel technology supports data confidentiality, data origin authentication and data
integrity of network information by utilizing encapsulation protocols, encryption algorithms and
hashing algorithms.
The products support following tunneling technologies to establish secure tunnels for data
communication, including IPSec, PPTP, L2TP (over IPSec) and GRE.
