I use snort both on my machine at home and on machines at work. Coupled with Shadow and a bit of elbow grease it's great.

Previously I worked with some other commercial products that automagically would crank out reams of reports to glitz the managers but didn't really do me much good.

Now it's a bit tedious for me to gen rpts when asked.

I guess there's always a trade off between what'll sell to the mgrs and what the techs actually need.
