Suggested facility with no protection (8)
I believe the answer is:
implicit
'suggested' is the definition.
(implicit can mean implied or suggested)
'facility with no protection' is the wordplay.
'facility' becomes 'simplicity' (both can mean ease).
'with no protection' says to take the centre (the letters which protect the rest are removed).
The middle of 'simplicity' is 'IMPLICIT'.
(Other definitions for implicit that I've seen before include "Meant though not stated directly" , "present, but not visible" , "Not actually stated" , "Inferred" , "Inherent but not made clear" .)
