UK's Leading Mobile Provider O2 Turns to Crossbeam Systems to Secure Its 22 Million-Plus Subscribers

Explosion in Smartphone Subscriptions Creates Massive Network Demand that Only Crossbeam's X-Series can Effectively Secure with a High-Performance Firewall Solution

BOXBOROUGH, Massachusetts, February 1 - Crossbeam Systems, Inc., the leading provider of next-generation security
platforms for high-performance networks, today announced that mobile phone
operator O2 in the United Kingdom, a division of Telefonica SA, is protecting
its mobile network of 22 million subscribers as well as its corporate
facilities with Crossbeam's X-Series security platform.

As the UK's exclusive distributor of Apple's iPhone for the last two
years, O2 has felt the full impact of the explosion in smartphone usage, with
an 18-fold increase in data traffic since the start of 2009. This traffic
continues to double every four months due to the growing popularity of
smartphones to surf the Web or watch videos.

Because smartphones allow a subscriber to open multiple, concurrent
Internet sessions — each of which must be secured — O2 needed a
high-performance network security platform that could scale with these
demands and turned to Crossbeam's X-Series to provide the solution.

"Every time a mobile user opens an application like Google Maps, it
automatically creates 20 or more sessions that need to be protected," said
Ian Waggott, head of technical security for Telefonica O2. "Crossbeam offers
the only solution that can easily handle the more than 6 million sessions
operating concurrently on our networks. As a mobile operator, it's imperative
that we can ensure the continued protection of our users as network traffic
and bandwidth demands grow, without impacting performance. Crossbeam is a
true visionary when it comes to delivering consolidated, scalable and
high-performance security."

Both O2 and its parent company Telefonica have been using the X-Series
for years to consolidate multiple security services on the chassis,
benefitting from the cost-savings, ease of management and power consumption
advantages of the platform. When O2 started experiencing the massive growth
in network traffic due to smartphone usage, the company reevaluated the
market's leading security vendors offering high-performance firewalls. Once
again, Crossbeam outperformed its competitors.

"When you look at high-performance firewalls, there are very few vendors
that can effectively do network address translations (NAT) under heavy
traffic loads," added Waggott. "Crossbeam's X-Series delivering Check Point's
firewall was by far the best solution on the market, delivering high
availability and throughput under real-world conditions, even with NAT
enabled."

Crossbeam's X-Series security platform virtualizes best-in-class security
applications on a scalable, carrier-class chassis. Customers benefit from a
simplified architecture that delivers high-performance security at the
industry's lowest total cost to operate — 40 to 70 percent lower than
competitors — and provides unparalleled flexibility, scalability and
built-in redundancy to intelligently manage traffic as security and network
demands change. Today more than 900 leading enterprises and service
providers, including 10 of the top 11 telecom carriers worldwide, rely on the
X-Series.

"The growing use of smartphones and other handsets has become an enormous
opportunity for wireless carriers," said Jim Freeze, Crossbeam's chief
marketing officer. "Customers like O2 realize that even as they scale their
networks to meet the data deluge, they still need to ensure the protection of
users. That's where Crossbeam has established its reputation and expertise,
providing a truly high-performance platform that gives customers the freedom
to deploy the best-of-breed security applications of their choice."
