I just learned about Guidance Explorer (from Alik Levin's blog), which has been out for about a year and a half now.  Looking for checklists and guidance for security reviews?  The team there seems to have quite a bit of detail compiled into sortable checklists.  I'm going to use this in some upcoming projects to get a better feel for it's usefulness to my work.
