Benefits of Enterprise VPN include cost savings, improved geographical coverage, simplified WAN operations, and increased networking reliability.

Service Provider VPN
Virtual Private Networks (VPNs) are a cornerstone of new world services. They are the key to staying competitive in the years ahead. VPNs deliver enterprise-scale connectivity deployed on a shared infrastructure with the same policies enjoyed in a private network. A VPN can be built on the Internet or on a service provider's IP, Frame Relay, or ATM infrastructure. The building blocks of any business-critical VPN service are security, quality of service, manageability, and reliability.
