I believe the answer is:

bolting

I'm a little stuck... Click here to teach me more about this clue!

'running away' is the definition.
(I've seen this in another clue)

'for security reasons' is the wordplay.
I cannot quite understand how this works, but
'for security reasons' could be 'bolt' (I've seen this before) and 'bolt' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Another definition for bolting that I've seen is " Running away without warning".)

I've seen this clue in The Globe and Mail.
