Westcon Group and Sipera Announce Global Distribution Agreement

Sipera VoIP Security Solutions Now Available through Westcon’s ConvergencePoint Program

Tarrytown, NY and Richardson, TX, April 11, 2006 – Westcon Group, Inc. and Sipera Systems, Inc. the leader in pure security for VoIP, mobile and multimedia communications, today announced that Westcon Group will be the global distributor of Sipera security solutions for real-time IP communications including VoIP, IM, video and multimedia.

By working with Westcon Group, Sipera plans to increase its worldwide channel presence by accessing the distributor’s network of security and convergence oriented customers, as well as leveraging Westcon Group’s powerful go-to-market capabilities through its ConvergencePoint program.

“As enterprises deploy standards-based protocols such as SIP for high-value collaborative applications, it is absolutely mandatory to assess risk and assure the security of these networks. Sipera’s comprehensive security solution is a key ingredient in our convergence solution portfolio, especially in end-to-end enterprise IP communications systems,” said Paul Cunningham, vice president of Westcon Group’s Technology Solution Group. “We believe our resellers are well positioned to offer Sipera IPCS 310’s real-time protection capability as a means to securely realize the benefits of IP communications applications from our foundation partners such as Cisco, Nortel and Avaya.”

“Westcon brings tremendous channels combined with a marketing and support track record that is unmatched in the industry,” said Joe O'Donnell, vice president of worldwide sales, Sipera. “Both companies are completely focused on enabling convergence, which creates great synergies between us. Sipera is especially excited about being an integral part of Westcon’s ConvergencePoint program to help bring its customers the best security solutions currently available for VoIP systems.”

The ConvergencePoint program, announced by Westcon Group last month, provides resellers with a vision, a roadmap and an environment to succeed in the convergence market by offering a broad range of products aimed at helping make businesses more efficient, along with powerful tools to enable their success, including SalesVision and LeadVision.

Sipera products will also be resold through the company’s Westcon, Comstor and VodaOne divisions, allowing resellers to offer Sipera’s security solution together with products from Cisco Systems Inc., Nortel Networks Corp., and Avaya, Inc.

“This agreement is a key milestone for Sipera as we scale our operations,” said Seshu Madhavapeddy, Sipera president and CEO. “Today’s enterprises are demanding comprehensive VoIP security that can be quickly deployed to protect their networks and end-users. Sipera IPCS products are ideally suited to Westcon‘s ConvergencePoint program.”
