Cynicism?
I think what everyone appears to be saying (or I hope, as it reflects my feelings); Is that these applications seem to be great, but we have been sold snake oil before that will solve all our problems except for (we later find out), 80% of all our real world problems.
At the end of the day defense in depth comes from getting all the non-sexy, expensive basics right, like patching, security zoning, two factor authentication, explicit authorisation etc. etc.
These products may be great and a wonderful investment, but they will be additional to all the other stuff, it won't solve the worlds security problems in isolation.
