Vocus Joins Arbor Networks Cloud Signaling Coalition to Stop the Evolving DDoS Threat to Data Centers

Cloud Signaling Connects On-Premise and In-Cloud Mitigation Infrastructure, Delivering Comprehensive DDoS Protection

CHELMSFORD, MA--(Marketwire - Sep 15, 2011) - Arbor Networks, Inc., a leading provider of security and network management solutions for next-generation data centers and carrier networks, announced today at Australian Network Operators Group (AusNOG) that Vocus Communications Pty Ltd (ASX: VOC), a provider of wholesale IP Transit and datacenters across Australia, has joined Arbor's Cloud Signaling(SM)Coalition (CSC), an innovative partnership between service providers, datacenter operators and enterprises with the mission to ensure the availability of their network infrastructure and speed time-to-mitigation for distributed denial of service (DDoS) attacks.

"Increasingly enterprise customers are looking to put their critical infrastructure into secure Internet Datacenters that are highly available. By participating in Arbor's Cloud Signaling Coalition, Vocus is able to offer our customers comprehensive, advanced DDoS attack identification and mitigation capabilities from both volumetric and application layer attacks. This complements Vocus' core strengths in datacenters and IP transit," said McDonald Richards, Vocus Communications chief technical officer.

"Surveys have repeatedly shown that security and availability are the primary barriers to the adoption of cloud computing. With the introduction of Cloud Signaling that connects the data center with service provider-based managed security services, Arbor is delivering the most comprehensive solution available today to ensure the availability of cloud resources," said Nick Race, Arbor Networks country manager for Australia and New Zealand.

Cloud Signaling: A Faster, Automated Way to Provide Comprehensive DDoS Mitigation
At the heart of Cloud Signaling are Arbor Networks Peakflow® SP and Pravail™ Availability Protection System solutions. Arbor Peakflow SP powers many of the world's leading cloud-based DDoS managed security services, while Arbor's Pravail Availability Protection System (APS) is an on-premise device that protects the Internet Data Center (IDC) edge against threats to availability -- specifically, protection against application-layer distributed denial of service (DDoS) attacks. Cloud Signaling is an efficient and integrated way of bridging the enterprise data center to the service provider cloud. Cloud Signaling connects the on-premise Pravail APS device with the cloud-based Peakflow SP solution, helping to ensure the availability of IDC infrastructures and speed time-to-mitigation for DDoS attacks. Arbor believes that the best way for enterprises, IDC and Cloud operators to have optimal protection against DDoS attacks is through this combination of on-premise and in-cloud protection.

Cloud Signaling Coalition: How does it work?
When an enterprise or data center operator discovers that they are under a service-disrupting DDoS attack, they can choose to mitigate the attack in the cloud by triggering a signal to upstream infrastructure of their service provider's network. A volumetric DDoS attack congesting the upstream links would immediately diminish or disappear altogether from the data center's access links, and service availability would be protected. Participation in the Cloud Signaling Coalition allows the service provider to provide differentiated managed security services, reduces the time to mitigation and increase the effectiveness of the response against DDoS threats, thus saving the customer from major operational expenses and preserving their reputation. Enterprise and IDC customers also benefit from real time monitoring of the attack mitigation, as well as granular post mortem reports with details of the attack and the steps taken by the service provider to mitigate the attack, keeping them in control and maintaining their expertise in command of the event.
