Google wants to buy cloud cybersecurity startup Wiz for $32 billion - here's why Wiz can become Google's largest acquisition.

Wiz's record $32 billion sale to Google, its biggest acquisition ever, rewards early investors like Sequoia Capital and Index Ventures.

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.
