2.1.2 SBOM Formats

The SBOM format is also a determining factor for interoperability across the software supply chain. Standardized formats provide a common data model that enables software producers, consumers, security tools, vulnerability management platforms, and compliance solutions to process and exchange software composition analysis information in a consistent manner.

ENISA’s SBOM Adoption State of Play 2026 mentions that almost 73% of the organisations use CycloneDX or SPDX.Table 2 presents the two predominant formats based on their current version.
