Outsourced SPAM control, Anti-virus Protection

and Content Filtering for Email

Postini Email Security (formerly Postini Perimeter Manager) delivers effective integrated email system security service that protects your company from email-borne threats before they reach your network. Postini Email Security provides comprehensive services to filter spam and viruses from email and to protect your email system from email attacks. The service also provides your IT organization with the necessary tools to manage email connections and regulate email delivery.

Postini Email Security provides the most control and flexibility for both administrators and end-users of any alternate solution. Postini is the only anti-spam solution to defend email systems against Directory Harvest Attacks (DHAs) - an aggressive technique spammers use to gather employee email addresses by running scripts against email servers. DHA propagation is the primary driver for the significant growth in spam targeted to corporate email users.

How does Postini Email Security Work?

Unlike other solutions that filter email at the desktop, server or gateway, Postini Email Security 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 secure data centres and scanned by their sophisticated heuristic-rules engine, which analyzes every part of an email message - from the IP address of the sender to the message content.

This process is executed in a highly secure, automated environment that prevents anyone from viewing legitimate email. And good email is not stored to disk. Postini Email Security provides tools that make it easy for administrators or end-users to review quarantined email, accept messages they would like to receive and create their own white lists and black lists.
