Postini, Inc.[1] was an e-mail, Web security, and archiving service owned by Google from 2007 until its closure . 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. In November 2011, Google announced the discontinuation of Postini in August 2012.
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]
The former company's services are now marketed as "Google Postini Services."
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.[citation needed]
