Sipera Systems Award-Winning UC Security Solution Undergoes Compatibility Testing With McAfee ePolicy Orchestrator Security Management Platform

Enterprise Security Managers to Gain Centralized Control Over Voice, Video, Collaboration, and SIP Trunks

RICHARDSON, Texas, April 19, 2011 - Sipera Systems, a leader in real-time Unified Communications (UC)
enablement and security, today announced that its award-winning UC-Sec
enterprise communications security solution is undergoing compatibility
testing with McAfee(R) ePolicy Orchestrator(R) (McAfee ePO(TM)) security
management platform.

When the testing is completed, security managers can gain visibility into
the entire spectrum of IP-based business communications — including voice,
video, data and web applications — from a single central management point.
This enables security managers to have unprecedented control over the
security of voice-over-IP, IP video conferencing, SIP trunks, collaboration
applications and other UC applications.

The Sipera UC-Sec appliance is a plug-and-play network device that
provides comprehensive security for real-time UC applications. As a
complement to the existing security architecture, the UC-Sec provides
application-layer firewalling, intrusion prevention, threat mitigation,
access control and policy enforcement in real-time for delay sensitive
applications.

The UC-Sec encrypts UC-traffic, terminates SIP trunks, forks media and
signaling for compliance, and permits an enterprise to safely and securely
extend VoIP and UC to any end point in any location. Sipera's customers use
the appliance to conduct secure VoIP on smartphones, in remote offices, to
distributed call center representatives and to enforce security policies on
all UC traffic in real-time.

The Sipera security system is undergoing compatibility testing as part of
its participation in the McAfee(R) Security Innovation Alliance (SIA)
program, which helps accelerate the development of interoperable security
products and simplifies the integration of these products within complex
customer environments.

Sipera's groundbreaking "Borderless UC" architecture enables all
communications to be encrypted and compliant on any UC device, at any
internal and external location.

"When UC-Sec achieves compatibility with the ePolicy Orchestrator
platform, enterprises will be able to easily manage UC and smartphone
security within their McAfee security management systems," said Andy Asava,
Vice President of Business Development at Sipera. "This testing, and our
participation in the McAfee SIA program, will help enterprises more easily
adopt desktop-based and mobile UC applications, ensure compliance with
industry security and privacy mandates, and streamline overall security
management."

"We're pleased to see Sipera Systems undergoing McAfee compatibility
testing for a solution that will be of interest to our joint customers," said
Ed Barry, vice president of the Security Innovation Alliance, McAfee. "The
integrated solution will ensure that VoIP/UC infrastructure and endpoints,
both mobile and fixed, are visible to the security manager for the first time
within McAfee ePO software."

The McAfee ePolicy Orchestrator platform is the first to let enterprises
and governments centrally manage security and compliance products from
multiple vendors, offering unprecedented cost savings and return on
investment. With more than 40,000 customers and managing more than 60 million
PCs and servers, this unique platform is helping McAfee SIA partners to
extend their reach and create complementary functionality.
