Your example sentence implies that attackers will benefit from high-grade security therefore ensures doesn’t work as you’d like it to in this case.

What should you say “The design of our works ensures high-grade security defence against both software and hardware attackers”.

Ensure can be used to guarantee a negative outcome but, as with any such sentence, the outcome itself needs to be correct.

With design our work ensures high-grade security for both computer and hardware attackers. Because

of the presence of the preposition’for’after’security’, the meaning of the sentence has become like ‘the design of our work ensures the security of the attackers (on behalf of them)?

The preposition with’security’ should be ‘against’: “The system is

designed to provide maximum security against toxic spills”

“The banks must tighten security against the fraud. I have already said that.” “There

is a difference in what the name of a given business is, and how does the business model fit in to it. “
