MOBILE ARMOR LICENSES CERTICOM TECHNOLOGY TO PROVIDE VPN SECURITY FOR MOBILE DEVICES

Data security system enables rapid deployment and secure management of services over-the-air

MISSISSAUGA, Ontario – (April 18, 2006)–When it comes to security, managed service providers (MSP) have a tall order: rapid deployment, multiple platform support, easy and secure management of services and upgrades to thousands of devices. Certicom Corp. (TSX: CIC) announced today that Mobile Armor is using Certicom technology to expand its wireless suite of security products to include IPSec for virtual private network (VPN) connectivity that meets the needs of MSPs.

"Mobile Armor provides the 'best of breed' mobile security solution for protecting critical data and information on mobile devices, laptops, and desktops," said Chand Vyas, chairman and CEO of Mobile Armor. "Integration of Certicom's highest quality, standards-based IPSec VPN functionality into our existing solution provides a secure and trusted method to wirelessly deploy and manage services."

Relying on Certicom's experience in developing security for resource-constrained environments, Mobile Armor was able to integrate a standards-based VPN client that is about one-tenth the size of the desktop version but with equivalent functionality. The Mobile Armor solution, with Certicom's VPN technology, provides the tools required to secure the enterprise, including cross-platform centralized management and reporting; data and network protection; and compliance and remediation. Mobile Armor's next-generation technology security solution currently ensures the data integrity of the U.S. Department of Defense, small to large enterprises and MSPs.

"By working with Certicom, Mobile Armor is able to accelerate its time to market with secure VPN connections that support leading platforms and gateways," said Ian McKinnon, Certicom's president and CEO. "Mobile Armor's solution offers mobile service providers the means to safely manage and deliver services 'over the air' with unparalleled security."

Under the terms of the agreement, Mobile Armor will pay a one-time license fee, professional services fees and royalties on a quarterly basis, on deployment of products.
