While the answers to some of these questions are predictable, others are surprising.
We will be presenting the answers to these questions in a talk at RSA Conference San Francisco 2013. If you're attending RSA and are interested in the answers to these questions, please join us on March 1st at 9.00 AM. A report delving into the details will be released after the conference, you can pre-register here and you will receive a link to the report once it's been published.
UPDATE: the full report has now been released, download it here
