Phil Zimmermann Joins BorderWare to Secure VoIP

August 15th, 2006

BorderWare Technologies and PGP (Pretty Good Privacy) founder Phil Zimmermann today announced an agreement to make BorderWare the first commercial licensee of Zfone, secure VoIP media encryption software, created by Zimmermann. This agreement tightly integrates Zfone with BorderWare´s SIPassure VoIP Security Gateway, bringing a new level of security and ease of use to VoIP systems.

VoIP and related real-time communication applications, such as video conferencing and instant messaging, continue to attract considerable interest worldwide, with millions of active private and business VoIP users today. Carriers and enterprises are increasingly seeing the benefits of VoIP services that allow voice messaging and video conferencing to be conducted securely, like email, as communications are transferred freely over traditional phone networks and the Internet.

By integrating Zfone media encryption with SIPassure, BorderWare is extending the VoIP security provided to organizations from threats such as Spam to Denial-of-Service attacks to include eavesdropping, spying and wiretapping, while delivering the same level of security and convenience that organizations have come to expect from email.

Zfone is secure Voice over IP. It uses a new protocol called ZRTP, which is better than other approaches to secure VoIP because it achieves security without the reliance on a PKI (Public Key Infrastructure), key certification, trust models, certificate authorities or key management complexity that bedevils the email encryption world. It does not rely on SIP signaling for the key management, and in fact, does not rely on any servers at all. It performs its key agreements and key management in a pure peer-to-peer manner over the RTP packet stream. It interoperates with any standard SIP phone, but naturally only encrypts the call if you are calling another ZRTP enabled device or phone. This new protocol has been submitted to the IETF as a proposal for a public standard, to enable interoperability of SIP endpoints from different vendors.

SIPassure is the industries first VoIP Security Gateway – a new class of product that offers the best features of an enterprise firewall, an Application layer gateway (ALG) and a Session Border Controller (SBC) to take security for VoIP applications to the next level. SIPassure is designed to secure all Session Initiation Protocol (SIP) based applications including VoIP services, video conferencing and other messaging applications. SIPassure ensures that organizations using SIP-based applications are safe from abuse and service disruption from internal and external malicious attacks, interference spam and other related threats. SIPassure sets a new standard for price performance for both the enterprise and carrier markets.
