Secure Extranet
Secure extranets allow a company to extend its network access securely to its strategic business partners while eliminating the need to install remote dial access or leased lines. Extranets are used for applications such as electronic commerce (E-commerce), with VPNs providing faster, more efficient bandwidth utilization than legacy E-commerce protocols, such as X25. VPNs allow for the ability to enforce authentication and authorization outside the enterprise firewall.
