Microsoft’s security division just got its own version of the shake-up that’s already hit the rest of the company this month.
Hayete Gallot, who took over as the division’s executive vice president in February, has replaced several senior executives who previously reported to her predecessor, according to a report by The Information.
Microsoft, the world’s largest cybersecurity software seller by revenue, declined to comment on the report, though NDTV said it independently confirmed at least one departure and one replacement.
Who’s out, who’s in, and what Gallot is prioritizing
Joy Chik, who spent close to three decades at Microsoft, and Shawn Bice, a four-year company veteran, were among the eight security leadership team members who reportedly left the organization. Bice’s LinkedIn profile also shows that he joined AWS in May.
Former security chief Charlie Bell, who joined Microsoft from Amazon in 2021, built the company’s Secure Future Initiative around a reported 34,000 engineers. He hasn’t left Microsoft; instead, he has shifted into a role focused on engineering quality.
To fill the gap, Gallot brought back Naseem Tuffaha, an 18-year Microsoft veteran who’d been away since 2022, as corporate vice president, alongside Rajesh Sundaram, a NetApp and Hewlett Packard Enterprise veteran.
Gallot is explicitly steering the organization toward an AI-first strategy, prioritizing tools like Microsoft Security Copilot, automated code-vulnerability scanning, and systems that monitor AI agents.
In an internal memo, she told staff that the industry is reimagining itself from the ground up and that the company now has to execute the hard choices it made months ago.
Gallot has also cut hundreds of roles within the division as part of that execution.
Why this fits the pattern of Microsoft’s broader AI restructuring
The timing lines up directly with Microsoft’s company-wide cuts announced earlier this month, 4,800 jobs, or 2.1% of its workforce, with Xbox absorbing the deepest hit at roughly 3,200 people let go under what its CEO, Asha Sharma, called the “Xbox reset.”
The parallel between Gallot and Sharma is hard to miss: both joined Microsoft in February, and both spent their first five months in the job cutting significantly into the teams they inherited rather than easing in gradually.
Gallot’s own path back to Microsoft adds another layer to the story. She spent 16 years at the company before leaving in 2024 for Google Cloud, where she led customer experience, and Satya Nadella brought her back specifically to run security, describing her as combining product-building instincts with a focus on customer value realization.
That she now reports directly to Nadella rather than through a broader engineering chain underscores how much weight the company is putting on security keeping pace with its AI push, especially given Microsoft’s position as the industry’s largest security vendor makes any leadership shake-up there consequential well beyond its own org chart.
Two of Nadella’s highest-profile February hires have now each used their first half-year in the building to make the same kind of call: keep the mission, replace much of the leadership underneath it. That’s a specific signal about what Nadella recruited both of them to do in the first place.
