On 15 August 2012, Google announced plans to migrate all Postini Google Message Security (GMS) customers to Google Gmail. After the change, all inbound Postini email will be routed through the native Gmail filtering service, and then pushed to the corporate mailbox. Administration will be through the Google Apps management console. The transition will begin in early 2013 and last 12 months.
Google’s email hygiene service Postini ranked low in Gartner’s May 2012 online customer satisfaction survey (see “Magic Quadrant for Secure Email Gateways” ), and this migration may relieve some of that dissatisfaction. Google Apps consistently upgrades its management console to reflect enterprise needs; Postini’s console rarely saw improvements. Gmail’s spam filtering is more aggressive, and in the new system, spam is quarantined in the Gmail inbox. That inbox can be activated to full send/receive capacity in the case of an on-premises email system failure — another feature that Postini lacked.
Google will save on development and operational costs. It will increase familiarity with the Gmail service and reduce switching costs and risk by providing Exchange customers with an alternative Gmail mailbox, integrating the enterprise directory with Gmail, and exposing administrators to the Gmail management console. However, some Exchange shops may dislike the forced changes and seek alternative suppliers such as Microsoft, Symantec, Cisco or Proofpoint.
Current and prospective customers should consider several factors when evaluating this Google action:
Microsoft is also integrating its cloud-based email hygiene service into on-premises and cloud versions of Exchange and Outlook. As a result, integrated inbound email hygiene services from these two email vendors will be acceptable for most enterprises. Those with more-demanding security requirements should still evaluate independent email security products and services. Specifically, advanced email data loss prevention, protection from targeted phishing attacks and encryption capabilities will require add-on solutions. Microsoft and Google will only gradually improve these functions over the next five years.
