I have come to know and respect Dana Epp for over 3 years now. The one thing I can say about Dana is he will always say it like he sees it , which is one reason I always value his feedback and opinion. When it comes to Security I can count on him to say where Microsoft needs to get a lot better and where we are doing good.
I recommend you read his blog on Microsoft Security Initiatives. Personally, I like his objective approach to Security. The comments are worth reading for sure.
