You make some excellent point David. The more I think about it I might go
with a comercial solution. I am afraid of adding anything else complicated
to the mix here as I am the only network guy here and if I leave I think my
shoes would be hard to fill as I run so many different things between Cisco,
Motorola, AS400, Citrix, Linux (snort) Windows yadda yadda. Why add the to
the complexity. " someone else is responsible/accountable if the product
fails to deliver!!" is the major kicker here for me. 8-)
I am mainly looking at Symantic Brightmail, Iron Port, Barracuda,
Cypertrust, Trend Micro (since we have there desktop AV solution).
