archaic0 asks: "I've recently acquired a new client (I do on call tech work for several companies where I live) who have requested a security audit. In the past I've hired several friends (self-proclaimed security consultants) in the industry to run various exploits and tests for me, but due to the time involved and the cost, I'd like to find a short introductory type option to start a new client off with. I recently ran across a program called Retina, by eEye, and I'm quite impressed however it comes with a $1400 price tag per use (or $14,000 a year for a bulk license). Can anyone point me to tools they've used to do a pretty well-rounded security scan that can produce detailed reports? I know there is no substitute for a real security professional spending time confirming your network security, but I'd like to have at least one good tool to start a new client off with before throwing a huge security team at them."
