Postini Perimeter Manager Listing updated: January 28, 2005

Postini Perimeter Manager is a hosted E-mail system security service that protects your company from E-mail-borne threats--before they hit your network. Postini's services filter out spam and viruses, protect your E-mail system from a wide range of attacks, and provide your IT organization with tools to secure E-mail connections and regulate E-mail delivery. Unlike other solutions that filter email at the desktop, server or gateway, Perimeter Manager is positioned between the Internet and your corporate network, creating a secure wall around your email system that extends to the email entry point — the Internet. All incoming email is routed through Postini's data centers and scanned by our engine, which analyzes every part of an email message — from the IP address of the sender to the message content.
