E-Mail Guard handles the security and management of corporate email by providing continually updated spam and virus filtering, content filtering, and protection from email-based directory harvesting and denial of service (DoS) attacks. E-Mail Guard also includes monitoring, reporting and content management tools plus outbound filtering to help you troubleshoot your email system and define and enforce corporate email policy.
E-Mail Guard is based on Postiniís Perimeter Manager, a pass-through service which routes all your email to secure, fault-tolerant data centers ó the same ones used by Google, eBay and Yahoo ó where messages and attachments are screened using heuristic rules analysis. Clean email is forwarded to your email server, and suspicious email is tagged and delivered or quarantined to a web-accessible storage area for you to review. E-Mail Guard can be set up quickly and works with any email system by redirecting your mail exchange (MX) record.
The E-Mail Guard service suite includes:
Perimeter Manager can also improve your email reliability. Postini's data center uptime averages 99.999 percent, far higher than small business email servers can expect to achieve. If your email server fails, messages are temporarily stored in a secure database at a Postini data center for delivery once youíre back on line. Perimeter Managerís load balancing technology restores recovered email by sending it at a measured pace in order to prevent your email server from being overwhelmed.
Perimeter Manager is also a powerful defense against Directory Harvest Attacks (DHAs). This is an aggressive technique used by spammers to gather employee email addresses by running scripts against email servers. DHA propagation is the primary driver behind the dramatic growth in spam targeted to corporate email users.

Why Does Progent Recommend Postini?
Gartner Research has recognized Postini as the number one spam filtering Managed Service Provider (MSP) with respect to the ability to execute. Postiniís administrative tools were recently cited by PC Magazine as the most advanced of any of the corporate anti-spam solutions they have reviewed, and in Network World's test of 16 anti-spam products Perimeter Manager scored the highest in accuracy for catching spam and delivered the lowest false-positive rate.
Postini processes over 1 billion messages weekly for over 2,700 customers and serves over 5 million end-users. The high volume of email processed makes Postiniís heuristic filtering engine continually more refined and efficient, and the companyís large customer base gives the Postini staying power that protects your investment in managed services.
Preserving Email Privacy
E-Mail Guard does not require users to provide personal contact or demographic information. Customers can deactivate services at any time by turning application settings off. Progent and Postini never sell or make available individual names, lists of users, or aggregate data to any third parties for gain. User configuration information provided to Postini is used explicitly to deliver services that match the clientís requirements and not for any other purpose. All user-specific information and email message information, including content, addresses, categorizations and IP addresses, are kept strictly confidential.
Impact on Email performance
Unlike store-and-forward solutions that use standard email server technology, Postiniís patented email processing method allows messages to be processed in real-time as the packets flow through the Postini servers. This also ensures that Postini does not expose customer data to hackers or potential loss of data. Postiniís filters process all email with no direct human contact with mail flow or individual messages. Mail messages are processed within milliseconds and immediately passed through to your email server. This eliminates any perceptible latency.
