I am not sure how fortinet does it however I know snort-inline now has a
clamav preprocessor that will scan for viruses in the traffic and block
it if discovered. There is no proxy involved and all traffic is scanned
based on a configuration you define. It is a recent development and sure
to require beefy hardware but might be worth exploring for the edge
points that require virus scanning. X-posting to snort-inline if they
want to chime in.

Does anyone know if Fortinet on-board virus scanning uses an SMTP
proxy server? Or is it able to accomplish this transparently by
simply inspecting the packets as most the IDS/IPS do.
We just purchased a new Proventia M10 from ISS and have discovered
that we cannot use it for Anti-Virus (email) or Anti-Spam due the
ffact that it uses an on-board SMTP proxy server that does not
support SMTP authentication among other issues. The IPS module does
not need the proxy and works fine. Having on-board virus scanning
at the network edge would be very helpful and Fortinet docs would
make you think it is ALL done with packet inspection and without
any nasty proxies in the middle. Does anyone know how this works?
TIA,
Don
