Google announced on Monday that the company had signed a definitive
agreement to buy Internet messaging security firm Postini for $625
million in cash.
The acquisition would allow Google to offer e-mail and
instant-messaging security as well as archiving and encryption services
without requiring customers to purchase additional hardware. The
offerings fit right into Google's current line-up of hosted
applications, such as GMail, Google Calendar and Google Docs &
Spreadsheets, Dave Girouard, vice president of Google Enterprise, said in a statement.
