Some vendors concentrated on hardware devices that provided a gateway and established communications channels across a public network. These devices included router capabilities and firewall security. Other vendors offered software solutions that ran on the server and the client workstation. In addition, several resellers and manufacturers bundled software and hardware to create a VPN. Others simply provided components, tools and utilities.
While the VPN market has stabilized with standards and products, traditional VPN service, based on ATM or Frame Relay, has given way to Internet Protocol (IP) and the Internet. IP-VPNs will be the central enabler of the new millennium economy, characterized by integrated global enterprises, electronic commerce, and just-in-time production, according to Cahners In-Stat Group.
IP-VPNs are taking market share away from traditional VPN services because of "lower costs, faster provisioning of service, improved security and greater ubiquity of service," said Henry Goldberg, senior analyst with In-Stat's Voice and Data Communications Service. According to a survey of VPN users, three-quarters of large U.S. organizations have either implemented an IP-VPN or plan to implement one within the next two years.
Managers have two options for implementing an IP-VPN: in-house, or as an outsourced service.
Goldberg said, "The vast majority of end-users currently implement in-house IP-VPNs, and there is no indication that this will change significantly for those planning future IP-VPNs. Outsourced IP-VPN service providers will have to do a much better job of marketing the advantages of outsourced IP-VPN service in order to gain market share."
