Global value chains are networks that spread a product or service across multiple countries, with different stages such as design, component manufacturing, software development, integration, logistics, and support handled by separate firms or facilities. They are central to modern industry because value is often captured not in basic production, but in the coordination, data, and standards that connect each stage.
In cyber security, global value chains matter because they expand the attack surface beyond one company or one country. A compromise in a supplier, cloud provider, logistics platform, or software integrator can affect many downstream partners at once. Attackers often exploit this by targeting third parties, shared updates, or weak identity controls. Defenders respond with supplier risk management, segmentation, access control, secure integration, and visibility into dependencies. For organizations, protecting a global value chain means securing both the technology and the trust relationships that keep it working.
