Virtual Private Networks (VPNs) use advanced encryption and tunneling to permit organizations to establish secure, end-to-end, private network connections over third-party networks, such as the Internet or extranets.

VPN's from Cisco are based on Cisco AVVID, the enterprise architecture that provides the intelligent network infrastructure for today's Internet Business Solutions.

Benefits of VPN Include:

• Cost Savings - By leveraging third party networks, with VPN, organizations no longer have to use expensive leased or frame relay lines and are able to connect remote users to their corporate networks via a local Internet service provider (ISP) instead of via expensive 800-number or long distance calls to resource-consuming modem banks.
  
• Security - VPNs provide the highest level of security using advanced encryption and authentication protocols that protect data from unauthorized access.
• Scalability - VPNs allow corporations to utilize remote access infrastructure within ISPs. Therefore, corporations are able to add a virtually unlimited amount of capacity without adding significant infrastructure.
• Compatibility with Broadband Technology - VPNs allow mobile workers, telecommuters and day extenders to take advantage of high-speed, broadband connectivity, such as DSL and Cable, when gaining access to their corporate networks, providing workers significant flexibility and efficiency.
