Source: Cisco Systems
Cisco IT uses Wide-Area Network (WAN) Virtual Private Networks (VPNs) to provide secure connectivity to remote Cisco sites, for extranet connectivity to partner sites, and to increase reliability for disaster recovery. Primary and backup connectivity using traditional dedicated circuits can be cost prohibitive. The challenge was to identify the right technical solution at the best price for each location. For sites that already have Internet access, IT can add a VPN connection without additional circuit cost. A reliable WAN VPN solution can help a company to be truly global, provide an additional safeguard in the event of a network disaster, and contribute to reduced circuit and hardware costs. Cisco Relies on WAN VPNs for remote access, extranet connections, and disaster recovery.
