Supply chain security refers to the strategies and practices used to protect every stage of a product or service’s journey, from sourcing raw materials to final delivery. In cybersecurity, it focuses on ensuring that all components, software, and vendors involved in the supply chain are trustworthy and free from vulnerabilities that could be exploited by cybercriminals or foreign actors. Effective supply chain security reduces the risk of tampering, data breaches, or unauthorized access, helping organizations safeguard their operations and sensitive information.
