About IP Filtering

InterScan™ Messaging Security Appliance (IMSA) includes IP Filtering, which consists of two parts: IP Profiler and Network Reputation Services (NRS).

 

IP Profiler

IP Profiler allows you to configure threshold settings and determine what action IMSA will take when it detects any of the four potential Internet threats:

Threshold settings—The maximum values that you can set for the various criteria in an IP Filtering rule. For example, the maximum number of recipients, maximum number of mails and so on.

 

NRS

Trend Micro Network Reputation Services (NRS) is designed to identify and block spam before it enters a computer network. NRS does this by routing Internet Protocol (IP) addresses of incoming mail connections to Trend Micro Threat Protection Network for verification against an extensive Reputation Database.
