WORLD'S LEADING CHEMICAL COMPANY, BASF, SELECTS POSTINI TO SECURE CORPORATE EMAIL IN 170 COUNTRIES

Postini Selected To Help BASF Optimize Its Email Architecture and Routing Strategy

SAN CARLOS, CA, September 19, 2006 — Postini, the global leader in Integrated Message Management, today announced that BASF, the world's leading chemical company, has selected Postini to secure its global email in 170 countries. Postini was selected over seven other on- demand service providers due to cost, service levels, functionality, and security. The ability to route mail through two different regions, to customize the handling of different mail streams, and to comply with international data security and privacy requirements were also key factors.

Due to the size and scope of BASF's worldwide reach, the company recently decided to optimize its email architecture by consolidating its multiple Internet email domains into a single global domain. To help manage this new architecture and protect the new global domain from a probable increase in spam and virus attacks, BASF turned to Postini due to its worldwide reputation as a trusted source of anti-spam and anti-virus protection.

"We consider email a mission-critical application, so our goal is to proactively address business risk by blocking spam and viruses before they can ever enter our company's email servers," said Brigitte Buchsrucker, senior specialist IS Architecture in BASF's Global Competence Center for Information Services. "Postini has a solid reputation in the marketplace. Its email security service is easy to manage, offering logical, intuitive administration tools requiring little administrative effort, which is very important to us."

Buchsrucker and her team also valued Postini's multiple regional data centers to address specific language, cultural, and security requirements and ensure the highest level of customer service. Postini currently operates data centers in Santa Clara (California), Chicago, London, Amsterdam, Zurich, and Geneva.

The initial email service switch for 35,000 European users over a single weekend was problem-free, eliminating any initial concerns BASF had about the combined rollout of email routing changes and news service introduction. With subsequent regional rollouts, a total of 60,000 BASF employees are now supported by Postini Perimeter Manager for Email. On average, Postini processes about 370,000 incoming messages a day for BASF, or about 11 million messages a month.
