Google parent Alphabet has struck a deal to buy cybersecurity startup Wiz for $32 billion in an all-cash transaction, in the tech giant’s largest acquisition ever.

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

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.
