How effective are Security Analytics tools and how do you compare their operational effectiveness?

After spending months researching this subject, Gartner's Dr. Anton Chuvakin says the long and short is that they just don't know how well the tools work as there isn't much data on the operational effectiveness of security analytics.

He points out that for analytics tools, many of the vendors have just 5-10 customers that have some data but it isn't enough. He tells Security Current's Vic Wheatman that a lot of stuff is very anecdotal and we only hear the success stories. So, he says it is hard to say, which type of a tool, model and statistics are working well. Listen to hear what you should do.
