Microsoft Security Division Cuts Hundreds of Roles During Engineering Restructure

Microsoft Corporation's cybersecurity division, led by Hayete Gallot since February, has undergone a major internal rebuild that included replacing senior executives, consolidating engineering teams, and cutting hundreds of roles. The restructuring is part of a push toward AI-powered security products such as Microsoft Security Copilot and code-scanning tools, and is intended to help the company capture spending now going to rivals like Anthropic and OpenAI. Leadership turnover included executives reporting to Charlie Bell, and the move follows broader security-focused changes at Microsoft since 2022 amid scrutiny from the Department of Homeland Security. Microsoft declined to comment on the changes; the cuts are described in internal communications reported by The Information and summarized by The Times of India.

Microsoft Corporation cut 300 jobs affecting its Cybersecurity / Security division team as of July 17, 2026.

That is roughly 0.1% of the 228,000 people Microsoft Corporation employs.
