TrustedSource - Global Intelligence to Protect Your Organization
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 SnapGear Appliances
Secure Computing integrated TrustedSource’s reputation scores with its SnapGear 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 SnapGear appliances in real time. This unique, stratified, architecture has enabled SnapGear appliances to block up to 80% of connections, increasing security levels while maintaining a false positive rate of less than one in one million.

TrustedSource Portal
This is a free online resource that provides precise information about email sender reputation by domain and IP address. Located at www.TrustedSource.org, the TrustedSource Portal is the only website in the world that provides administrators a view into current and historical reputation and sending patterns of the senders, as well as analytical information such as country of origin, network ownership, and hosts for known senders within each domain. Additionally, the TrustedSource Portal provides a snapshot of global email trends, including a map illustrating country of origin for email attacks, graphs displaying overall email and spam volume trends, Secure Computing's ZombieMeter, and a snapshot view of email authentication deployments across the Internet.

Technologies:
Threat Response
Secure Computing’s worldwide R&D team monitors and analyzes email threats globally to keep our customers continually protected. The outputs of this research, called ThreatResponse Updates (TRU), are used to automatically update Secure Computing appliances in the field. This protects Secure Computing customers by continually providing optimal configuration settings for up-to-the-second protection and the highest possible levels of inbound threat security.

Connection Control
Combines two critical protection technologies (traffic shaping and reputation services) to allow Secure Computing to dramatically increase message handling capability and reduce the cost of fighting spam.

Message Profiler
The first technology to integrate and correlate signature- and content-based detection techniques into a single, combined engine, using a variety of advanced algorithms to examine thousands of characteristics for every message. This creates a precise score for each message, determining the probability that it is spam or some other threat.
