Trend repulses spam

The services represent the first offering resulting from the company's acquisition last month of Kelkea, an IP filtering and reputation services provider.

Trend Micro says its Network Reputation Services respond directly to the continuing growth and difficulties of tackling spam. It points to Gartner's finding that approximately 90 per cent of enterprise inbound email is considered spam.

It claims the services will stop between 40 to 80 per cent of connections from known offending IP addresses from sending suspicious email into a network.

“By stopping the bulk of spam at the IP address, our services protect customers from the rising threat of zombie attacks and botnets, both of which utilise spam-like techniques,” said Eva Chen, CEO of Trend Micro. “These new services will ultimately help customers optimise bandwidth and other resources for business-critical operations.”

Trend Micro Network Reputation Services consist of the following offerings:

• Trend Micro RBL+ Service: involves checking lists of suspect IP addresses from four databases - an open-relay list, open proxy list, a real-time black-hole list, and a dial-up user list.

• Trend Micro Network Anti-Spam Service (NAS): consists of a dynamic list that queries a database focused on dynamic behavioral monitoring of suspect zombie PCs. µ
