A VPN is an extension of a private
network that encompasses links across shared or public networks such
as the Internet. Using the IP connectivity of the Internet along
with a combination of tunneling and data encryption, VPNs help
securely connect remote clients and remote offices. Virtual Private
Networks (VPNs) allow organizations to securely extend their LANs
over the Internet by encrypting the data traffic. VPNs create the
ideal infrastructure for providing a secure method for the exchange
of data and network resources with employees, partners, vendors and
external clinics.
