Unisys, Nortel Networks Unveil Secure VPN for Financial, Government, Commercial Markets

BLUE BELL, Penn.–(BUSINESS WIRE)–April 24, 2001–Unisys Corporation (NYSE:UIS) and Nortel Networks (NYSE:NT)(TSE:NT.) have developed a virtual private network (VPN) solution – called Secure VPN – that is expected to help financial institutions, government departments and commercial enterprises conduct secure, cost-effective eBusiness over the Internet.

Demand for VPN products and services continues to rise sharply according to Infonetics Research, with global VPN expenditures expected to increase 528 percent by 2004. To meet the needs of this expanding market, Unisys and Nortel Networks have created an end-to-end VPN solution by combining Unisys professional consulting and integration services with Nortel Networks Contivity platform.

Secure VPN is a comprehensive network security solution designed to enable financial, government and commercial institutions to conduct eBusiness over the high-performance Internet at lower cost than private networks with a high degree of security.

Helping enterprises create secure VPNs is a key objective of the Unisys Security Architecture, a holistic approach through which Unisys marshals solutions and services enabling customers to build a multi-layered security infrastructure for eBusiness in transaction-intensive network environments.

“Secure VPN provides unique value for customers by capitalizing on Unisys proven expertise in delivering integrated, secure solutions for financial services, public sector and commercial markets with Nortel Networks leadership in high-performance Internet solutions,” said Andy Galt, managing director, Alliances, Unisys Global Network Services. “Together we provide a comprehensive and economical way to build a secure network infrastructure for transaction-intensive, enterprise-wide eBusiness.”

As the central platform for Secure VPN, Nortel Networks Contivity provides tunneling and authentication capabilities for reliable network security and remote access at reduced costs. Contivity creates robust IP VPNs for businesses building managed secure networks, providing an ‘all in one’ VPN solution for remote access and site-to-site VPN services in a highly-scalable and highly-available platform.

Unisys integrates Contivity with a comprehensive portfolio of security consulting and network design services. Secure VPN enables businesses to leverage existing applications and develop new ones, resulting in secure, reliable networks. Businesses can also take advantage of additional options such as wide area networking (WAN), network/policy management and IP (Internet Protocol)-based mobility offerings for a customized solution.

“Nortel Networks leadership position in high-performance Internet solutions, combined with Unisys expertise in eBusiness security and network integration, enables a solution that can enhance our customers’ business models,” said Kevin Goose, vice president, solutions integrator and consultant sales, Nortel Networks. “Working with Unisys, we have created a compelling, end-to-end solution that provides optimal network security in the financial services, public sector and commercial markets, and extends our enterprise reach.”

Each Contivity VPN Switch is a single hardware device that provides routing, firewall, bandwidth management, encryption, authentication and data integrity for secure tunneling across managed IP networks and the Internet. With Contivity VPN switches, businesses can connect remote users, branch offices, suppliers and customers with the cost and performance advantages of shared IP networks and the same level of security and control as private networks.
