Siemens, a large enterprise in the United States with over 50 thousand employees and $25 billion in annual revenue, faces significant security challenges due to its complex systems and large network of suppliers. Kurt John, Chief Cybersecurity Officer at Siemens USA, shares insights on how the company manages security risks and leads its transformation into a data-first, cloud-first company. The key to their success lies in collecting real-time data and analytics, which enables them to detect anomalies and flag potential security threats quickly. This approach also has operational benefits, such as improving efficiency and reducing costs. Additionally, Siemens is leveraging digital twins technology to transform its business model, with applications including internal efficiency, production operations, training for technicians, and customer-facing solutions. By scaling a real-time data layer, modernizing applications, and optimizing hybrid clouds, IT leaders can find short-term benefits through cost, efficiency, and other operational improvements, while the longer-term benefits come from learning customer needs and deploying real-time experiences.
