Cloud SignalingSM technology connects on-premise and in-cloud mitigation infrastructure, delivering comprehensive DDoS protection

Arbor Networks, Inc., a leading provider of security and network management solutions for next-generation data centers and carrier networks, announced today that Nexusguard, a premium provider of end-to-end, in-the-cloud, Internet security solutions, has joined Arbor’s Cloud Signaling Coalition (CSC). The CSC is an innovative partnership between service providers, data center 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.

Headquartered in Hong Kong, with another office in Taiwan, Nexusguard operates a globally distributed (fully-meshed) network of DDoS attack mitigation scrubbing centers. Nexusguard is committed to providing clients with highly customized, high-quality, low-latency and cost-effective DDoS protection.

“Nexusguard is committed to providing the most up-to-date, innovative DDoS mitigation solutions available today. Arbor Networks not only provides the world’s most advanced and broadly deployed DDoS mitigation products, they have created a truly innovative way of connecting the customer premise with the service provider cloud, via Cloud Signaling technology. By participating in Arbor’s Cloud Signaling Coalition, we can assure our customers that we are on the leading edge of DDoS protection, “said Donny Chong, head of marketing for Nexusguard.

“Nexusguard and Arbor are committed to solving the DDoS problem for customers. To do so requires collaboration among all stakeholders, from vendors like Arbor to the enterprise and its in-cloud service provider. Because Arbor is so broadly deployed and our solutions are powering so many cloud-based DDoS security offerings, more than fifty to date, Arbor is in a position to connect cloud-based protection with on-premise protection for seamless, complete protection against DDoS attacks,” said Attley Ng, Arbor Networks vice president of sales for Asia Pacific.

Cloud Signaling Technology: A Faster, Automated Way to Provide Comprehensive DDoS Mitigation
At the heart of Cloud Signaling technology are Arbor Networks’ Peakflow® SP and PravailTM Availability Protection System devices. The Peakflow SP device 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 data center edge against threats to availability – specifically, protection against application-layer DDoS attacks. Cloud Signaling technology is an efficient and integrated way of bridging the enterprise data center to the service provider cloud. Cloud Signaling technology connects the on-premise Pravail APS device with the cloud-based Peakflow SP device, helping to ensure the availability of data center infrastructures and speed time-to-mitigation for DDoS attacks. Arbor believes that the best way for enterprises, data centers and cloud operators to have optimal protection against DDoS attacks is through this combination of on-premise and in-cloud protection.

Cloud Signaling Technology: How does it work?
When an enterprise or data center operator discovers they are under a service-disrupting DDoS attack, they can choose to mitigate the attack in the cloud by triggering a signal to the upstream infrastructure of their service provider’s network. A flood-based 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 increases the effectiveness of the response against DDoS threats, thus saving the customer from major operational expenses and helping to preserve their reputation. Enterprise and data center 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 mitigating steps taken by the service provider, keeping customers in control and maintaining their expertise in command of the event.
