Alphabet Inc. is in talks to purchase cloud-security company Wiz Inc. for $33 billion, restarting discussions that were called off last summer after extended negotiations, according to people familiar with the matter.

The companies didn’t disclose Wiz’s revenue in disclosing the deal and Alphabet didn’t respond to a request for information about that figure. But multiple media outlets have reported that Wiz had $500 million of annual recurring revenue at one point during 2024 and aimed to reach $1 billion in 2025.

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.
