A technical tutorial on SBOMs and Vulnerability Exploitability eXchange that explains how software inventories become product-specific exploitability decisions, how VEX information is represented and exchanged across CISA, CSAF, CycloneDX, SPDX, and OpenVEX, and how trust, lifecycle management, automation, interoperability, and regulatory obligations under the EU Cyber Resilience Act shape their practical use.
