Google acquired the company for $625 million in cash.
"With this transaction, we're reinforcing our commitment to delivering compelling hosted applications to businesses of all sizes. With the addition of Postini, our apps are not just simple and appealing to users -- they can also streamline the complex information security mandates within these organizations," said Eric Schmidt, Chairman of the Board and Chief Executive Officer of Google.
Hosted services, like Google Apps and Postini solutions, provide organizations with high quality communications tools without the expense and hassle of traditional on-premise solutions. Google Apps, which includes Gmail, Calendar, Talk, Docs & Spreadsheets, and Personal Start Page, has been adopted by more than 100,000 businesses already. Postini solutions include Email Security, IM Security, Web Security, Message Archiving, Message Encryption, and Policy-enforced TLS.
"The response to Google Apps has been tremendous, with more than 1,000 small businesses signing up for the service every day. At the same time, large businesses have been reluctant to move to hosted applications due to issues of security and corporate compliance. By adding Postini products to Google's technology, businesses no longer have to choose -- employees get the intuitive products they want, and the company achieves the security and assurance it needs," said Dave Girouard, Vice President and General Manager, Google Enterprise.
