Packets then are routed over these connections on an ad-hoc basis.

The two fundamental security features of a VPN are to keep intruders out of a private computer network and to encrypt all information leaving a LAN so that unauthorized users are unable to read or modify it.

A VPN can dramatically reduce telecommunication expenses by making use of internet connectivity, which tends to be much lower in cost relative to the use of leased communication lines.

The main operational concept for VPNs is IPsec, encryption, packet tunneling, and firewalls.
