Because rebels are sneaky sorts who might have tricks that they try to use.
(Now, I can see the First Order blokes, being the arrogant sods that they are, might make that assumption. But, absent critical concerns elsewhere that require the resources, it seems awfully negligent to not take safeguards.)
(On the other hand yet again, both militaries seem rather quite terrible at being military organizations. This would not be out of place for Star Wars.)
Thx!

At the very least you would expect the FO to ask themselves "Why did the Resistance run here? Maybe they have allies on those planets, lets go check them out" and then at the very least do flyovers of them all.
But yes, both sides are in a race to the bottom of the barrel of incompetence.
