Google’s parent company Alphabet on Tuesday struck a deal to acquire cloud security startup Wiz for $32 billion. The deal is easily the largest in Google’s history and bolsters its cloud business as it competes against other tech giants like Microsoft and Amazon.

“Wiz and Google Cloud share a vision to improve security by making it easier and faster for organizations of all types and sizes to protect themselves, end-to-end, across all major clouds,” Google said in its announcement of the deal. “This will help spur the adoption of multicloud cybersecurity, the use of multicloud, and competition and growth in cloud computing.”
