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.
Cisco VPNs 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 - VPNs enable organizations to utilize cost-effective third-party Internet transport to connect remote offices and remote users to the main corporate site, thus eliminating expensive dedicated WAN links and modem banks. Furthermore, the advent of cost-effective, high-bandwidth technologies like DSL, organizations can use VPNs to reduce their connectivity costs while simultaneously increasing remote connection bandwidth.
