Alphabet said on Tuesday it would buy Wiz for about $32 billion in its biggest deal ever, as the Google parent doubles down on cybersecurity to sharpen its edge in the cloud-computing race against Amazon.

Google’s parent Alphabet said Tuesday that it had agreed to buy cybersecurity company Wiz for $32 billion in cash, marking the tech company’s largest purchase to date. The acquisition combines Wiz’s security platform with Google’s cloud infrastructure.

The acquisition could make the Silicon Valley giant a bigger force in cybersecurity, and arrives months after an earlier round of talks collapsed.
