Winners will make the hard choices: Microsoft's security chief to employees after layoffs

Microsoft's cybersecurity business is being rebuilt from the inside out, and the person running the overhaul isn't being quiet about what it takes. Hayete Gallot, who took charge of the division in February, has replaced several senior executives, consolidated engineering teams, and cut hundreds of roles as she pushes the world's largest cybersecurity software seller toward AI-powered products. In an internal memo, she told staff the industry is being "reimagined from the ground up." The message was blunt about what comes next. "It will reward the companies that see the shift early, make the hard choices, and execute with discipline," Gallot wrote, per The Information, which first reported the shake-up. "A few months ago, we made those choices. Now we must execute."
