Redwood City, CA-August 26, 2009-Altor Networks, provider of best-in-class virtualization and cloud security solutions, and the Nielsen Company, the world's leading supplier of marketing, media and TV ratings information, will be teaming up to deliver a compelling session on virtualization security best practices.

The hour-long session(TA-2405) will take place on Wednesday September 2nd at 2:30 pm.

In order to deliver the metrics on which the media industry depends, the Nielsen Company must operate large data centers capable of analyzing enormous volumes of information. The company's challenges are shared by any organization that deals in the consolidation and processing of information and applications. Like similar firms in the media, financial services, manufacturing and healthcare sectors, Nielsen has turned to virtualization in order to take advantage of efficiencies in space and power consumption. Doing so however, creates unique challenges when it comes to securing the information containing therein. This is where Altor Networks and the company's expertise in the development of a purpose-built firewall for virtualized environments can help enable secure mission critical traffic flow.

Join Nielsen and Altor as they share their experience for best practices in the implementation and optimization of virtualized environments and sustainable security for those networks.

Altor will also be demonstrating the latest version of its firewall at booth # 2313.
