The short answer, yes and yes.
Stephen Dubner gathers opinions from Bruce Schneier, Tal Be’ery (Imperva), Henry Harrison (BAE Systems Detica), Julie Conroy McNellery (Aite Group), and David Jevans (IronKey).
McNellery seems to think that PCI has been a success and has reduced the number of breaches. While the number of credit card breaches has dropped, it appears that it’s because so much credit card data has been stolen that the price for credit card data has been driven down so low that cyber criminals are focusing on other types of digital information to steal.
Just ask Josh Corman.
