Wiz, a cloud security firm based in New York, has rejected a proposed $23 billion acquisition deal offered by Google parent Alphabet, according to a Wiz memo seen by CNBC.

Acquisition talks between companies can be very unpredictable — and, especially in today’s world of Big Tech, often open the door for antitrust concerns. Google is no stranger to that. The main pillars of the tech giant's empire — internet search and digital advertising — have become so powerful that the U.S. Justice Department is trying to undercut them in two separate lawsuits.
