Free from danger or risk (6)
I believe the answer is:
secure
'free from danger or risk' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for secure that I've seen before include "Incapable of being tampered with" , "Firm; safe" , "Firmly fixed or free from uncertainty" , "Obtain - safe" , "Safe; make fast" .)
