Google parent Alphabet is in advanced discussions to acquire cybersecurity startup Wiz for approximately $23 billion, according to sources familiar with the situation.

The Wall Street Journal reported that the deal, if finalized, would be Google’s largest acquisition to date. The negotiations are progressing, and a final agreement could be reached soon, provided the talks do not fall through.
