Virtual Private Networking (VPN) is one of the fastest growing information technology market segments today. VPNs enable companies to securely connect their offices, mobile workers, and business partners using a protected tunnel through the public infrastructure, like the Internet. VPNs are an economical means to extend an existing corporate network infrastructure, and as an alternative to typical leased lines, can be easier and more rapid to deploy. ADTRAN's NetVanta 2000 Series of VPN products address this growing Internet security need. Each product in this series includes IPSec VPN tunneling, access policies, stateful inspection firewall, cyber assault protection, Network Address Translation (NAT), IP routing, and authenticated remote user access. The NetVanta VPN Client is a software implemented VPN solution that also includes a full-featured firewall for laptops or personal computers targeting the mobile workforce. The feature rich NetVanta 2000 Series is a must for companies requiring a VPN/firewall solution.
