Email reputation: Advanced identifies and stops sources
of spam while they are in the process of sending millions of messages.
This is a dynamic, real-time antispam solution. To provide this
service, Trend Micro continuously monitors network and traffic patterns
and immediately updates the dynamic reputation database as new spam
sources emerge, often within minutes of the first sign of spam.
As evidence of spam activity ceases, the dynamic reputation database
is updated accordingly.
Like Email reputation: Standard, Email reputation: Advanced is
a DNS query-based service, but two queries can be made to two different
databases: the standard reputation database and the dynamic reputation
database (a database updated dynamically in real time). These two
databases have distinct entries (no overlapping IP addresses), allowing
Trend Micro to maintain a very efficient and effective database
that can quickly respond to highly dynamic sources of spam. Email
reputation: Advanced has blocked more than 80% of total incoming
connections (all were malicious) in customer networks. Results will vary
depending on how much of your incoming email stream is spam. The
more spam you receive, the higher the percentage of blocked connections
you will see.
