The nadir of this process was him insisting that we shut down a "Code Red Infected Server". Too bad it turned to out be a developers Apple iBook.

My point with all this is what you do with the scans AFTER you run them. If you want intelligent analysis of the report, you get a security professional that knows how to check things manually and knows when output from the scanner looks dubious. Any reasonably intelligent person can operate the scanner software and print out the report when its done. The skill and expertise comes in interpreting the output and making meaningful suggestions that actually improve security.
