Microsoft Security Overhaul Cuts Jobs, Bets Big On AI

Quick Reads

• Microsoft is overhauling its security business around AI and has already cut several hundred jobs.
• New security chief Hayete Gallot leads the changes and reports directly to Satya Nadella.
• The focus centers on tools that fight AI threats with AI, including Security Copilot.
• Microsoft folded its threat-intelligence tools into one Defender portal this week.
• The push aims to win back security spending flowing toward Anthropic and OpenAI.

Microsoft’s security overhaul marks a major shift for the world’s biggest cybersecurity vendor, rebuilding its business around AI. Consequently, the changes introduce more AI-driven security tools, fewer traditional products, and merged engineering teams. As a result, the shift has already cost several hundred jobs, according to The Information.

Meanwhile, money and fear are driving the decision. Companies increasingly fear AI-powered hacks, while more security budgets now flow to Anthropic and OpenAI instead of Microsoft. Therefore, Microsoft wants to win that spending back. Hayete Gallot has led the transformation since February after 15 years at Microsoft and a Google Cloud leadership role. She reports directly to CEO Satya Nadella. Moreover, her message was clear: the industry is being rebuilt, and Microsoft must execute quickly.

Accordingly, the new strategy focuses on AI tools that combat AI-powered threats. For example, Gallot is advancing Security Copilot for code scanning alongside tools that monitor AI agents for risks. Importantly, every autonomous AI agent creates another potential entry point for attackers. Therefore, Microsoft aims to sell the guardrails that reduce those risks. Already, Microsoft has unified threat-intelligence tools in one Defender portal and launched expert-led Defender services.

Meanwhile, Microsoft’s retreat from older security products appears intentional, according to The Next Web. Instead, the company presents itself as a cheaper, all-in-one alternative to competing AI labs. Ultimately, Microsoft is betting it can sell protection against AI-driven attacks before rivals capitalize on the threats.
