CERTICOM'S MOVIANVPN OFFERS ADVANCED SECURITY WITH WIRELESS ACCESS OVER NORTEL NETWORKS CONTIVITY VPNS

HAYWARD, Calif., August 21, 2001 - Certicom (Nasdaq: CERT; TSE: CIC), a leading provider of mobile e-business security, has signed an agreement with Nortel Networks* to bundle a 30-day trial of Certicom's movianVPN™, the industry's first broadly interoperable IPSec wireless virtual private network (VPN) client for handheld devices, with Nortel Networks Contivity* VPN Switch. With this solution, Nortel Networks' customers can extend their Contivity VPNs to popular handheld computing platforms. Certicom has also joined the Nortel Networks Contivity Associates Program to enhance their joint customer experience through marketing and technical collaboration. 

movianVPN will benefit wireless operators by helping them overcome the unique security, power, and processing requirements of a mobile environment where devices such as PDAs run on batteries and have lower processing capacity. 

As part of today's announcement, Certicom's movianVPN software will be shipping with Nortel Networks family of Contivity VPN switches. This will enable enterprises to provide secure wireless access to their Contivity-based corporate VPNs. After a 30-day trial, corporations can license the movianVPN client directly from Certicom. movianVPN allows companies to extend critical enterprise applications such as e-mail and customer relationship management (CRM) tools to mobile professionals using popular PalmOS® 3.5 or Windows CE 3.0-based devices. 

Previously, Certicom announced that Nortel Networks licensed elliptic curve cryptography (ECC) for the Contivity VPN Switch, which enables a fast connection between Certicom's client and the VPN gateway. Certicom's ECC technology is ideally suited for securing wireless devices that are limited by low processing speed, network bandwidth and battery power. 

"Nortel Networks users are strongly represented in the deployment of movianVPN today, and we are excited that this agreement will get the product into the hands of the IT professional as conveniently as possible," said Jennifer Vancini, managing director at Certicom. "Today's announcement represents an important relationship with an industry leader, and demonstrates Certicom's foothold in providing enterprises with capabilities for leveraging their VPN infrastructure to small devices."
