sentence construction - Help parse "There is much more to preventing employee crime than background checks..."

Consider:

There is much more to preventing employee crime than background checks and traditional audits. It's not just about the employees you don't know; some of the biggest crimes are committed by long-tenured employees who have gained the corporation's trust.

--When the Cat’s Away by Doug Karpp Link

I understand the first sentence this way:

As to preventing employee crime, there is much more than background checks and traditional audits.

I think preventing is a gerund here. Preventing employee crime couldn't be semantically in parallel with background checks and traditional audits.

Is my understanding correct?

And I ran across this sentence before:

There is much more to the universe than meets the eye on earth.

Does this have the same structure as the former one? Can you please adjust these two to a more straightforward version or template?

Answer

Your parse is correct.

The underlying idiom is [quantity Y] to X, meaning X consists of [quantity Y].

a hundred cents to the dollar
two cups to a pint
ten millimeters to a centimeter

With measures like these you may also say in X (“two cups in a pint”), and when you are talking of properties of X you use of (“five stages of growth”); but when X is a target or goal, you use to, often with steps as the Y:

Six Steps to Success
Three Steps to Better Health

(Note that this is not the same as [quantity Y] for X, which does not imply that the Y units are sufficient to achieve X, merely that each contributes to achieving X. And it is not the same to which is used with infinitives: Three ways to improve your health.)

You may also use indefinite quantifiers like some Y or a few Y, or comparative quantifiers like more/fewer than [quantity] Y or more/fewer Y than [quantity].

There are [more than two cups] to a quart.

And of course any such quantifier can also be employed as a pronoun, with the ‘unit’ Y understood. That’s what is going on in your sentence; indeed, the notion of units has dissolved into something uncountable like activity, so the verb becomes singular.

There is [much more than background checks and traditional audits] to [preventing employee crime].

Finally, the sentence has been rearranged to put the focus on the inadequate checks and audits.
