Port Scanner Reports

[jeff.brossette () gmail com]

All,

I am looking for a port scanning tool (software or hardware, open
source or commercial) that I can configure to run on a regularly
scheduled basis, say
once a week or once a month, for around 500 internal servers and
workstations (Unix/Linux, Windows and Novell).

The goal is to produce a "diff" report that will identify any new
ports that have been opened on any of the servers or workstations from
the previous scan.

This would need to be a completely automatic process that would email
out the results after each scan cycle.

Are there any products that can perform this task?

Thanks,
Jeff B.
