Which cyber security tool should I go for?

Recently I was discussing the problem of cyber security with one of my colleagues. He said, " Cyber security tools play an important role when it comes to the protection of sensitive and private data of businesses as well as individuals." Something in those lines, and this I absolutely agree with.

The point where we did not agree on was the choice of cyber security tools- CIS and Wireshark. Which do you think is better?
