In my experience, a productive 3rd party "value add" is having the
"stated policy" of the firewall verified periodically-- and keeping this
audit-type function in the hands of a party other than the firewall
admin is a wise thing.   

We've found that what many sites _believe_ they have implemented as a
policy is remarkably different from what is actually happening on the
wire.  MJR's quote about "seatbelts worn around the neck" applies.
