Sipera Systems' Solutions Streamline, Simplify VoIP Security for Payment Card Privacy Compliance

PCI Security Standards Council Issues New Guidelines to Protect Credit Card Data in VoIP Applications

RICHARDSON, Texas, March 28, 2011 - Sipera Systems, the leader in real-time Unified Communications (UC)
enablement and security, today announced its innovative VoIP security
solutions enable rapid and simple compliance with new guidance issued by the
industry council for payment card privacy.

Earlier this month, the PCI Security Standards Council (PCI SSC) issued
new guidance to protect credit card and payment card information in
telephone-based transactions, including VoIP. The guidance advises businesses
that handle credit cards to ensure the privacy and encryption of VoIP
communications carrying cardholder data, and to control archiving and
monitoring of these communications in compliance with PCI Data Security
Standard (PCI DSS) rules.

Sipera's award-winning security appliance solution provides comprehensive
application-layer security for VoIP, enabling an enterprise to implement
these important security controls simply and easily.

"Many in the security community have recently focused on VoIP and Unified
Communications application security as essential for safeguarding financial
transactions of all kinds," said Adam Boone, Vice President of Marketing and
Product Management for Sipera Systems. "The new guidance regarding payment
card privacy is a critical development in this area, because VoIP
communications are widespread and are now a favored target of hackers and
fraudsters."

Pre-integrated and interoperable with enterprise VoIP infrastructure from
all leading manufacturers, Sipera's UC-Sec provides a complete
application-layer security architecture for VoIP and UC in one simple
appliance. The UC-Sec enables an enterprise to comply with the PCI SSC
guidance on VoIP security with these capabilities:

    - Provides application-layer encryption and privacy to any
      supporting end-point.
    - Forks both signaling and media for monitoring and recording of
      clear traffic, even when it is encrypted, enabling centralized call
      recording and simpler architectures.
    - Enables full privacy of communications to remote call centers,
      and teleworkers, traveling workers, with no VPN appliances or
      concentrators to configure and manage.
    - Safely supports SIP trunks with the industry's best protection
      against toll fraud, eavesdropping and intrusion.
    - Supports advanced access control and user authentication,
      including clientless two-factor authentication, for VoIP phones.
    - Enables compliant VoIP and Unified Communications to VoIP phones,
      smartphones, soft-clients, video phones and other devices.
    - Complements an existing security architecture and compliance
      processes, including firewalls, IDS/IPS and other functions.

Sipera also offers the breakthrough E-SBC solution, a highly
cost-effective enterprise Session Border Controller. The E-SBC enables
enterprises to adopt low-cost SIP trunks to decrease telecom costs, while
enhancing the security architecture and preparing the enterprise for advanced
Unified Communications applications.
