Innovative, proprietary anti spam filters

Many competitive products rely on existing publicly available spam filtering tools, like SpamAssassin and statistical filtering. Our SpamFilter ISP was first released in 2002. During these years, we at LogSat Software developed several proprietary filters to stop spam. Both the SFDB (SpamFilter Distributed Blacklist) and the SFDC (SpamFilter Distributed Content) are centralized databases, updated in real-time by thousands of SpamFilter installation throughout the world. SpamFilter ISP was the first product able to scan images or spam, even when they were being embedded in PDF files.
