PRESS RELEASE

HOLLYWOOD, FL — (November 17, 2011) — Prolexic Technologies, the global leader in Distributed Denial of Service (DDoS) mitigation services, today announced that it has created a data forensics and analysis group that will provide detailed pre- and post-attack data to clients as a subscription service. The new group and service is called Prolexic Security Engineering and Response Team (PLXSERT).

Formed in February 2011 as an internal research group, PLXSERT has been providing data forensics to select clients based on its insight into global DDoS threats and activities, as well as specific client attacks. Feedback from clients has been so positive that the service is now being made available on a subscription basis to all Prolexic clients.

“We are on the front lines counteracting more DDoS attacks daily than any other company and this provides a very rich data source to mine,” said Neal Quinn, vice president of Operations at Prolexic. “Our hope is that the data and insight PLXSERT is providing can help organizations make more informed decisions and be proactive in defending against DDoS attacks.”

PLXSERT is currently providing DDoS threat information in two forms. Threat Advisories are being issued to clients on an ad hoc basis, proving insight into specific threats, including steps clients can take to defend against them. PLXSERT is also compiling data on a quarterly basis and will issue attack reports that provide insight into Prolexic’s mitigation activities for the most recent threemonth period, including the volume of attacks, the most common attack types, and countries where attacks are originating. The first attack report for Q3 2011 can be downloaded from www.prolexic.com/attackreports.

The PLXSERT service can provide value to customers both before and after attacks. With intelligence gleaned from monitoring threats around world it is possible to identify botnet characteristics without having received any DDoS traffic. As a result, organizations can be alert and prepared ahead of time before an attack begins. Similarly, deep post-attack analysis can provide best practices to help minimize the impact of future attacks.

“PLXSERT lays the foundation for a more intelligent approach to DDoS monitoring and more successful mitigation,” said Quinn. “What has helped us internally win against DDoS attackers is now being made available to our customers.”
