If that was true, do you honestly think Linux would be as popular as
it is? I never used cyberguards, so I can't state for sure which is
easier... However, if you know what you are doing it is no problem to
manage dozens of linux machines centrally. Certainly much easier then
dozens of windows boxes running checkpoint, etc....

*You* might need to, but I certainly would not have to patch every box
separately or modify rules separately, etc... I think you are
confusing linux with Windows.... (actually there are way to do things
centrally with windows too, but IMO it's much easier in Linux to
centralize and lower your TCO).
If anything, Linux TCO is higher when N is small. There is a slightly
higher learning curve (no higher then Unix) to be proficient at it.
As N grows, the ability to centrally manage it grows and the
difference between managing 10 boxes or 100 is minimal (not couting
actual hardware maintenance). Unlike windows, going from 10 to 100
can easily be tripple the work...
