I think that the main argument for not deploying ISA in an internet
facing environment is because of the underlying OS; Windows.
Windows has been under attack for how many years now? I believe that if
windows is locked down appropriately it can be used as described above.

This:
" The only last point I'd make is that I'd be hesitant in deploying ISA
in an internet facing role (although I do and have done that before) -
but I don't really have a justification for this aside from "it just
doesn't feel quite right".
"
..statement is something that is expressed fairly often, but fortunately
has not a single grain of substance to it. To James' credit, he does
qualify his hesistation...
I know it sounds like marketing spew, but the simple fact is; in 5+
years of service on anything from an SBS server, OEM appliance to HUGE
enterprise deployments, ISA server has the distinction of not having
been the recipient of one single exploit in the wild.
Yes; we've shipped patches for it and the odds are (realistically
speaking), we may well do so again. So do Cisco, Juniper, et al and we
don't hear the "just doesn't feel right" when they need patching.
Contrast this with literally *no other* firewall maker (truthfully)
making this claim and you have quite a piece of information at your
disposal when you present your options in CxO-land.
