Microsoft is restructuring its cybersecurity business, introducing leadership changes, team consolidation and workforce reductions as it shifts its focus towards AI-powered security products.
The overhaul is being led by Hayete Gallot, who took charge of Microsoft’s cybersecurity division in February. According to _The Information_, the company has replaced several senior executives, reorganised engineering teams and eliminated hundreds of roles as part of the transformation.
In an internal memo to employees, Gallot said the cybersecurity industry is being fundamentally reshaped by artificial intelligence and called on teams to execute the company’s new strategy with greater discipline.
The restructuring is aimed at strengthening Microsoft’s AI-driven cybersecurity portfolio, including products such as Microsoft Security Copilot, AI vulnerability- detection tools and software that helps organisations monitor and secure AI agents.
The workforce changes build on Microsoft’s broader efforts to strengthen its security operations following increased scrutiny over cybersecurity incidents in recent years. The company has also made security a core performance expectation for employees, incorporating it into performance evaluations.
As part of the reorganisation, Microsoft has reshuffled several leadership positions. Gallot has appointed new executives to key roles, including the return of Microsoft veteran Naseem Tuffaha and the hiring of Rajesh Sundaram, who previously held leadership positions at NetApp and Hewlett Packard Enterprise.
The latest changes reflect how AI is reshaping workforce priorities across the technology sector. Companies are increasingly reorganising teams, redefining leadership roles and investing in AI-focused capabilities as cybersecurity becomes a strategic area for future growth.
