Postini, Inc. [1] was an e-mail, Web security, and archiving service owned by Google since 2007. It provided cloud computing services for filtering e-mail spam and malware (before it was delivered to a client's mail server), offered optional e-mail archiving, and protected client networks from web-borne malware.
Postini was a startup company founded in 1999 by Shinya Akamine, Gordon Irlam, Brian Maggi, and Scott Petry in Redwood City, California, United States. [2] [3] It was backed by August Capital, with second-round funding from August as well as Summit Partners Accelerator Fund and Sun Microsystems. [4] By February 2005, it was operating ten U.S. data centers, processing 2.5 billion e-mail messages weekly, and providing anti-spam services for more than 4,200 companies and "6 million end users, including workers at Merrill Lynch, Circuit City, Rayovac, and Hormel Foods, the company that makes Spam, the canned meat product". [2] Later in 2005 it moved to nearby San Carlos, California. [5] As of 2012, the number of processed emails is estimated to have been doubled around two times, and Google has added data centers in the EU to better serve its European customers.
On July 9, 2007, Google announced that it had signed a definitive agreement to acquire Postini. [6] Google paid $625 million in cash for the acquisition. [7]

In September 2011, Google announced it would discontinue a number of its products, including Google Web Security, which was acquired by Google as part of Postini. [8] On August 21, 2012, Google announced it would be shutting down all of Postini's web services and folding the service's users into Google Apps. [9] After a multi-year migration effort, the last customers were migrated to Google Apps in the second half of 2015.
