PRESS RELEASE

BOXBOROUGH, Mass.—September 10, 2009—Crossbeam Systems, Inc., the leading provider of next-generation security platforms for high-performance networks, announced today the availability of a whitepaper titled "The Emergence of Two Clouds." The whitepaper is designed to help IT managers understand the unique challenges of securing virtualized environments and provide insight into a new best practices-based architecture that can greatly simplify management operations, while improving the flexibility and adaptability of the two current options: physical appliances and virtual security appliances.

"For network security, there are significant consequences to mass deployment of virtualization technology," said Jon Oltsik, principal analyst at Enterprise Strategy Group. "Crossbeam's whitepaper elevates the discussion to help IT staff take advantage of security virtualization—which introduces a host of complex issues related to inter-VM traffic boundaries and VM sprawl. These concepts need to be better understood in order to move security virtualization forward from a great concept to a well-articulated security strategy."

Today, the potential security risks associated with virtualizing data centers are significant, leading many IT managers to stop short of virtualizing everything in the data center. Despite the advancements in virtualization, there is still a fundamental lack of knowledge and best practices that can help IT managers understand the consequences of a fully virtualized infrastructure and, most importantly, avoid the operational pitfalls.

"One of the biggest challenges IT managers face is the complexity of managing trust boundaries between Web, application and database VMs once the physical connections are removed," said Jim Freeze, Crossbeam's chief marketing officer. "Ironically, in an effort to protect between the virtualized layers, they end up replacing appliance sprawl with virtual machine sprawl and opening the door to new levels of risk. As the pressure mounts to virtualize more mission-critical IT infrastructure, the question of whether security virtualization can be done successfully is top of mind. The answer is yes, but not in a traditional IT architecture."

"The Emergence of Two Clouds" whitepaper outlines a third approach that creates a "two cloud" environment between the virtualized applications and the network security infrastructure. This enables companies to maintain trust boundaries and meet performance and reliability requirements, without losing any of the flexibility and adaptability benefits of a virtualized infrastructure.

"Once you have separated security from the application infrastructure, the problems associated with security virtualization are eliminated," added Freeze. "For instance, Crossbeam can centralize control of hundreds of virtualized services such as firewall and IPS and allow IT operations to manage traffic flow dynamically through the appropriate security service depending upon which trust boundary the data is crossing. Deploying these services on the X-Series platform gives IT managers the flexibility they need to scale and provision security services, without experiencing degradation in performance."
