Sierra Wireless Embeds Certicom's movianVPN Client in new Voq Professional Phone(TM) Tuesday May 11, 7:02 am ET New smart phone to provide business users with secure e-mail capabilities while leveraging existing security infrastructure MISSISSAUGA, ON, May 11 /PRNewswire-FirstCall/ - Certicom Corp. (TSX: CIC - News), the authority for strong, efficient cryptography, today announced that Sierra Wireless (NASDAQ: SWIR - TSX: SW) has embedded movianVPN(TM) by Certicom into its VoqMail(TM) Professional Edition (VoqMail Pro) wireless e-mail solution, offered for the new Voq Professional Phone(TM). As an embedded feature that supports multiple VPN gateways, the solution is designed to offer IT managers minimal administration and a better return on their existing security infrastructure investment. Based on the Microsoft Windows Mobile(TM) software for Smartphones, the Voq Professional Phone was developed specifically for enterprise users and mobile professionals. The product is designed to offer vital business applications, such as e-mail, and strong security for sensitive and confidential information. A key feature of the Voq Professional Phone is the ease with which the movianVPN client can be integrated into an enterprise's existing security infrastructure and its minimal impact on performance and battery life of the phone. By making security an integral part of VoqMail Pro and its VoqManager desktop IT provisioning tool, and not a separate add-on, Sierra Wireless has created a turn-key enterprise and business data access solution that saves time and effort by eliminating the need for IT managers to work with third parties to buy and configure software and policies for each device. "Voq was developed specifically for the needs of the business professional, and the IT Managers that support them. During development we recognized that a key requirement of the enterprise was the ability to integrate a VPN client without comprising the end user experience or increasing the burden on IT administrators," said Andrew Harries, senior vice president of marketing for Sierra Wireless. "Working with our partners, we believe we have succeeded in building a powerful product that provides a strong, user- and IT-friendly solution." For over 15 years, Certicom has focused on developing and providing security for constrained environments. This expertise has resulted in a wireless VPN client that is one-tenth the size of desktop versions but with equivalent functionality. It provides strong security, including confidentiality, integrity and authentication from handheld devices to the corporate network. movianVPN, an award-winning wireless VPN client, meets the IPSec standard to provide secure access to the corporate network via wireless handhelds. movianVPN fits with existing infrastructure by supporting more than a dozen gateways, including those from Cisco, Netscreen and Nortel and the three leading operating systems - Microsoft Windows Mobile, Palm OS and Symbian OS - including the various versions of the platforms. "The combination of Sierra Wireless' deep experience in the wireless market and their diligence in developing the Voq Professional Phone to meet specific end user requirements has resulted in a Smartphone that addresses today's needs of the enterprise. They have optimized the user experience while focusing on process, security, and power management," said Roy Pereira, vice-president of marketing and product management at Certicom. "We believe the Voq Professional Phone will become a real success story in the mobile market." Sierra Wireless announced the VoqMail Personal and Professional Edition software on February 11, 2004, introducing an always-there(TM) e-mail experience and providing easy-to-use, cost-efficient, and secure access to corporate e-mail.
