TIS Gauntlet 4.0 (and some other firewalls - I believe) support something
Content Vectoring Protocol (CVP) - which I have not really looked into yet. It
allows you to pass email messages, or attachments, or web pages to a CVP
server running on your internal network. From the documentation this can
then scan for viruses, or for undesireable content.
I dont know if CVP is documented anywhere - you may be able use
a firewall which supports it, and write or buy in a scanning engine which
would meet the company policy.
