Traffic Control Email Firewall - Overview

Most anti-spam systems block connections from known spam senders. But spam from new or unknown senders still has to be filtered – and filtering eats up server resources.

Traffic Control adds another powerful tool to the anti-spam arsenal: the ability to slow down traffic from suspicious and unknown sources. With their bandwidth reduced, spammers have no choice to but to move on to easier targets. The net result is as much as a 95% reduction in the number of servers required to process email, and less spam reaching end users.

Handles up to 100,000 concurrent SMTP connections

Traffic Control easily manages tens of thousands of connections, and provides load balancing features to ensure that downstream mail servers are never overloaded. Most mail servers can handle no more than a few hundred connections at a time.

According to data collected from an Ivy League university, Traffic Control is 99.6% effective at eliminating botnet spam. By slowing connections from unknown sources, it eliminates much of the spam that blocking systems miss. An innovative connection multiplexing scheme allows Traffic Control to slow down incoming connections without overwhelming downstream servers with connections.
