This next generation Reputation Filter by e-mail security leader IronPort Systems allows ISPs to stop spam from originating in their networks. The first generation of Reputation Filters only looked at inbound traffic. IronPort System's Product Marketing Director Pete Schlampp said spammers took advantage of that weakness and found ways to lessen the impact of the filters.
By Jack M. Germain TechNewsWorld 12/04/04 1:30 AM PT IronPort Systems is arming some of the largest ISPs with a new type of Reputation Filter powered by the SenderBase E-mail Traffic Monitoring Network. This filtering system gives the computer industry a new tool in blocking spam coming out of ISP's so that compromised or infected computers, known as zombies, cannot deliver their spam mail payloads. "Through SenderBase we see that over 70 percent of all spam originates from consumer broadband users," IronPort System's Product Marketing Director Pete Schlampp told TechNewsWorld. So far, six of the 10 largest ISP's and five of the 10 largest media companies in the world are using IronPort's Reputation Filters, he said.
