Hi @bkimmerich

Does security centric need to be hyphenated (security-centric)?

Also some of the bullets end in  an ellipsis (...) is that shorthand for etc.,? 

The final bullet under 'options' starts with a ? - the sentence seems to be in shorthand/unfinished.

Risk centric approach - does it need a hyphen?  Also, point 1.1 (make ) needs to be completed

Pls advise, thanks
