Trend Micro fights spam based on reputation
Expanding its antispam offerings, Trend Micro on Monday announced new services to help midsized and large organizations block junk e-mail. The Trend Micro Network Reputation Services aim to stop spam using a list of IP addresses that are known to be sending spam or should not be sending e-mail at all. These include open e-mail relays and proxies, and IP addresses used for dial-up Internet users, Trend Micro said.
The new services are the result of Trend Micro's acquisition last month of Kelkea, which had been providing similar services since 1996. The Network Reputation Services is meant to complement traditional e-mail scanners. Trend Micro offers two versions of the services, a basic real-time black-listing service and an enhanced version with dynamic protection against spam-sending zombie PCs.
