Today’s spammers are determined to get their messages across and are constantly adapting their techniques to sneak past spam filters. It’s an ongoing cycle of offense vs. defense. Technologies such as heuristic detection and Bayesian filtering were initially effective, but spammers have found ways to circumvent even these once-robust protections.

With its TrustedSource reputation system, Secure Computing® has turned the tables on spammers. Rather than depending solely on localized protection using algorithms that are quickly obsolete, TrustedSource uses a global reputation approach to proactively identify and block traffic from illegitimate sources. The essential components to effectiveness of this solution are:

- Volume of reputation data – TrustedSource sees more email sent to enterprises and governments than any other messaging security technology in the world
- Quality of reputation data – TrustedSource correlates reputations assigned to each identity by intelligently aggregating the global behavioral and sending pattern knowledge available for each sender
- Accuracy of reputation data – TrustedSource conducts real-time behavior analysis using over 30 behavior classifiers that examine over 1000 characteristics and typically identifies over 250,000 new zombies a day

TrustedSource collects information on email senders and the types of email they generate by accumulating data from over 7000 sensors located in 51 countries. As it gets more data, the breadth and depth of the TrustedSource accuracy increases, accurately categorizing sender reputations, decreasing spam, and instantly blocking attacks.

Constant Feedback with IronMail Appliances

Secure Computing integrated TrustedSource’s reputation scores with its IronMail appliances in 2002, providing real-time behavior analysis on more than one-third of the world’s enterprise messaging traffic. TrustedSource feeds its global intelligence to locally-based IronMail appliances in real time. This unique, stratified, architecture has enabled IronMail appliances to block up to 80% of connections, increasing security levels while maintaining a false positive rate of less than one in one million.
