Business Editors/High-Tech Writers

REDWOOD CITY, Calif.--(BUSINESS WIRE)--June 11, 2002

Delivers Comprehensive Robust Security, Integrated Management,

Superior QoS and Multi-gigabit Performance

Check Point Software Technologies Ltd. (Nasdaq:CHKP), the worldwide leader in securing the Internet, today announced comprehensive and integrated support for corporations seeking to securely deploy Voice over IP (VoIP) as a cost effective alternative to traditional telecommunications. Check Point's Secure Virtual Network Architecture (SVN(TM)) provides the industry's most comprehensive support, integrated management and highest performance for securing converged networks.

Traditionally, companies could not allow VoIP into their networks securely. With other products, allowing VoIP traffic means permitting third-party products to open holes in the security policy, which introduces the risk and potential for various types of network attacks. As customers begin to combine voice and data traffic into a single, converged network, they must ensure full security, manageability and performance including: authorization, authentication, confidentiality and integrity. Check Point's patented Stateful Inspection technology recognizes and inspects complex VoIP protocols for any possible threats, enabling an optimized level of security and performance for the entire telephony session.

Check Point's SVN architecture natively recognizes and prioritizes Session Initiation Protocol (SIP) VoIP traffic on virtual private networks to uniquely provide robust security, Quality of Service (QoS) and privacy for a truly secure end-to-end IP telephony solution. These benefits will enable corporations to securely deploy IP telecommunications with:

-- Comprehensive Security Support -- Native and comprehensive support for all
VoIP protocols including, SIP, H.323, RTP/RTCP, and compatibility with network
address translation for secure communications

-- Enhanced Reliability -- Integrated prioritization, high availability and
queuing of latency-sensitive VoIP traffic over VPNs using Check Point's
FloodGate-1(R)

-- Ease of Management -- Integrated enterprise-wide VoIP policy management with
detailed logging and auditing through Check Point's SMARTCenter

-- Multi-gigabit Performance -- Faster throughput with Stateful Inspection when
compared to competing proxy-oriented VoIP security solutions

"Our respective development teams have been collaborating closely to ensure that SIP and H.323 products will traverse the firewall securely," said Jacob Bridger, vice president of marketing and business development, Technology Business Unit of RADVISION Ltd. (Nasdaq:RVSN). "We're pleased to work with Check Point to solve what has been up until now an inhibitor in the enterprise VoIP market."

"As corporations look to deploy VoIP as a cost effective transition from traditional telecommunications, true end-to-end security should not be an afterthought, but a complement to the communications plan," said Carol Stone, vice president of marketing for Check Point Software Technologies. "Check Point is enabling companies to deploy secure next-generation converged networks that will integrate with their existing security infrastructure."

Availability

Enhanced VoIP security is available immediately across the entire line of Check Point Next Generation solutions.
