A Virtual Private Network (VPN) is a network that uses the Internet or other network service as its Wide Area Network (WAN) backbone. In a VPN, dial-up connections to remote users and leased line or Frame Relay connections to remote sites are replaced by local connections to an Internet service provider (ISP) or other service provider's point of presence (POP). A VPN allows a private intranet to be securely extended across the Internet or other network service, facilitating secure e-commerce and extranet connections with business partners, suppliers and customers.
