Postini: Google's take on e-mail security

From CNET News.com: The computer security industry historically borrows military defense concepts to combat digital threats, literally creating war rooms where experts follow attacks in progress on huge screens with phones ringing off the hook.

Not so at Google's Postini e-mail security service provider unit. Instead, computerized systems monitor 3 billion messages per day that flow in and out of customer systems and pass through Postini's thousands of machines in data centers around the U.S. and in Europe before hitting the Internet. The Postini system is highly automated, distributed, and scalable, characteristic of all of Google's operations.

Google's Gmail antispam efforts are separate from those of Postini, which Google acquired two years ago, although it follows similar computerized operations and the teams have started to integrate the processes.

Postini represents Google's commercial push into e-mail security, offering a subscription-based service to more than 50,000 customer companies and organizations and more than 15 million business users. In addition to protecting e-mail from spam and viruses, Postini offers compliance and archiving services.
