Given the ease of sharing data, our sensitive information is going more places that we want it. We have means to secure data, but you really can't do that if you don't know where your data actually is.

This week's episode is hosted by me, David Spark (@dspark), producer of CISO Series and Andy Ellis (@csoandy), operating partner, YL Ventures. Our sponsored guest is Brian Vecci (@BrianTheVecci), field CTO, Varonis.

Thanks to our podcast sponsor, Varonis

Everyday, your employees share thousands of sensitive files with too many people, exposing data to the entire organization – or even the entire internet. Varonis monitors sharing link activity and intelligently eliminates links that aren't needed – reducing your risk on a continual basis.

• What is this generated yet unused data? Is this the same as ROT data or redundant, obsolete, trivial data?
• How can it be discovered and classified?
