For new customers, LuxSci has introduced the Email Defense premium Spam and virus filtering service to replace Email Guard, our former premium filtering service.

Email Defense is very much like Email Guard, except that:

• Email Defense has three layers of virus filtering: Sophos, McAfee, and internal proprietary rules. Email Guard only had two layers – Sophos and internal.
• Email Defense adds Symantec Brightmail Anti-Spam to its stack of Spam filters. Brightmail has millions of “honeypot” email addresses used to continuously trap and classify Spam. Combined with all of the filtering already present in Email Guard, including statistical filtering, industry heuristics, proprietary heuristics, reputation analysis, URL filtering, and reputation-based RBL filtering, Email Defense now catches an even larger percentage of Spam with even fewer false positives.

Existing clients using Email Guard will be able to continue to use it indefinitely. Email Guard is fully supported and you can continue to add new users and new domains. Existing Email Guard clients who wish to upgrade to Email Defense will be able to do so starting at the beginning of the second quarter of 2005.
