Google is making the biggest acquisition in its history. The company's parent company Alphabet is buying Wiz, the cloud security startup, for $32 billion

Google on Tuesday signed a "definitive agreement" to acquire New York-based cloud security startup Wiz for $32 billion in an all-cash deal. In July, CNBC reported that Wiz walked away from a potential $23 billion acquisition by Google and announced to employees that it would pursue an IPO instead.

Google has struck a deal to buy cybersecurity firm Wiz for $32 billion in what would be the tech giant's biggest-ever acquisition at the same time it's facing a potential breakup of its internet empire.
