This is a charade - multiple separate word parts are joined together in sequence to form the answer.
'Regarding' gives you the first part. 'Those unidentified' refers to multiple people with a common placeholder name used for unknown individuals. 'Technology' is abbreviated. Put all three parts together in order.
Answer: OVERDOES IT | OVER (regarding) + DOES (multiple 'Does' - as in John Doe/Jane Doe for unidentified people) + IT (information technology) = OVERDOES IT (goes too far)
