Google Cloud’s customer chief returns to Microsoft as head of security

Microsoft has a new head of security. Hayete Gallot, who left Microsoft in October 2024 to become the president of Google Cloud's customer experience, is returning to the software giant as the executive vice president of security, reporting directly to CEO Satya Nadella.

The move means Charlie Bell, formerly Microsoft's security chief, is taking on a new role at the company. "I've also asked Charlie Bell to take on a new role focused on engineering quality, reporting to me," says Nadella, in an internal Microsoft memo.
