Unlike traditional on-premise appliance and software products, the feature-rich, highly reliable service leverages a multilayered strategy to successfully keep more than 99% of destructive messages out of the business environment. Primary to Anti-Spam’s email defense effectiveness is its Stacked Classification Framework® spam detection system, which utilizes a patented method of identifying and controlling spam using a voting algorithm based on a sophisticated form of intelligent reasoning to achieve more than 99% accuracy.

Within the Framework, the different spam filters separately assess and “vote” on the probability that a specific email is spam a technique that results in highly- accurate threat protection with industry-leading low false positive rates (legitimate email misidentified as spam). Furthermore, as new spam-detection techniques and filters are developed, AntiSpam can rapidly and seamlessly integrate them into the flexible Framework.
