Women’s Month is a good moment to recognize how much modern manufacturing depends on cybersecurity leadership that can protect global operations without slowing production, innovation, or supply chains. The women in this feature work across industrial giants, advanced manufacturing environments, and multinational enterprises where cyber risk touches everything from plant systems and enterprise applications to governance, privacy, and board-level decision-making. Together, they reflect how manufacturing security now sits at the center of resilience, modernization, and operational trust.
