A supply chain gateway is a security checkpoint within an organization's software development or deployment pipeline. It is designed to inspect, verify, and validate all incoming software components, dependencies, or updates sourced from third-party vendors or external repositories before they are integrated or deployed into production environments. The primary purpose of a supply chain gateway is to detect and prevent the introduction of malicious code, vulnerabilities, or unauthorized changes that could compromise the security of the organization’s systems. By acting as a control point, the supply chain gateway helps ensure that only trusted, vetted, and compliant software components are allowed to proceed, thereby reducing the risk of supply chain attacks and enhancing overall cybersecurity posture.
