I had a chance to check out Fastvue’s TMG Reporter’s Reports and I can tell you, these things are really amazing! I wish I had access to these reports during the ISA firewall days – I could have been an instant heroine! 
Seriously, the TMG firewall stores a lot of great information in it’s logs, but historically that great information was locked up in the logs and you had to make it an avocation just to get the information you needed out of these logs. Fastvue fixes that.
