Postini™ services secure and managed email systems, without the need for software or hardware. Using patent-pending pass-through technology (versus store-and-forward methods). Email bound for a company's email server is processed in real-time through a highly secure service architecture.

Within milliseconds, Postini's award-winning email security solution separates spam and viruses from legitimate messages. Legitimate email is instantly passed on to the destination mail server. Suspicious email can either be quarantined in a web-based, password-protected message center for administrator or end-user review, or tagged and delivered. The entire process is fully automated and virtual – valid emails are not stored or written to disk, nor are they physically accessed by any persons other than the recipient or authorized administrator.
