Pre-integrated solution saves communication device manufacturers valuable time and development costs

VON, San Jose, CA, USA and Tel-Aviv (March 17, 2008) –

SafeNet, Inc, a global leader in information security, and RADVISON, a leading provider of products and technologies for unified visual communications over IP and 3G networks, today announced their joint commitment to securing and enabling next-generation fixed and mobile IP communications. This partnership and resulting joint solution unites two historically separate technologies: IPsec security–a network level protocol–and SIP data management–an application level protocol–to save customers valuable time and development costs.

The pre-integrated, IPsec-protected IMS signaling solution provides device and equipment manufacturers within the telecom and networking industries with a complete set of tools for building next-generation mobile and fixed network capable applications including Voice and Video over IP (V²oIP), video share, multi-party gaming, video and audio conferencing, and content sharing.

“SafeNet and RADVISON bring complementary skills to the table. SafeNet has 25 years of experience in delivering best-in-breed IPsec security solutions to the industries leading telecom and networking OEMs, said Sagi Subocki, products manager, Technology Business Unit, RADVISION. “RADVISION is recognized at the industry’s leading provider of advanced software building blocks which support the development of standards-compliant products for emerging 3G and IP networks. This fit makes a compelling partnership, both for us and for our customers.”

RADVISION’s award-winning SIP Developer Suite is a powerful and highly versatile set of tools to dramatically accelerate fixed and mobile network element development. It includes a suite of Toolkits, Add-Ons and Testing Tools that enable developers to combine the necessary components to create an exemplary development environment for virtually every device’s specific needs. Through the joint partnership, SafeNet’s industry-leading IPsec security toolkits will be pre-integrated with RADVISION’s SIP Developer Suite, including a specific solution for IMS-enabled network applications. SafeNet’s IPsec security solution will enable device and equipment manufacturers within the telecom and networking industries to protect signaling traffic – from the gateway to the end user equipment – for access, IWLAN, and inter-network communications.

“In the mobile industry specifically, the fast and affordable delivery of cutting-edge mobile applications including V²oIP are one of the few ways operators and service providers can differentiate themselves in a highly competitive environment,” said Simon Blake-Wilson, managing director, mobile and networking solutions, SafeNet. “We are proud to partner with RADVISION to provide customers with a secure, fast, cost effective, and easy to integrate foundation for bringing these next-generation features and services to market.”

The companies’ pre-integrated solution for the IMS-enabled networks is fully compliant with IETF, 3GPP, 3GPP2 and TISPAN standards.
