Shared DMZ liability

[todd () susq com (Allen Todd)]

Hi,

I'm interested in whether anyone has any specific 
knowledge about corporate liablility resulting from
the use of a shared DMZ for external data providers.

Currently, we setup a seperate DMZ for each external
vendor but we are under management pressure to reduce
costs for a remote office by consolidating multiple 
vendors onto a single interface.  I am worried that
the vendors will be able to see each others traffic
on the DMZ and what kind of exposure this would 
bring to my company.

Thanks for any input or references,

Allen Todd
