GUAC (Graph for Understanding Artifact Composition) is an OpenSSF incubating project that ingests software security metadata such as SBOMs, SLSA attestations, and vulnerability advisories into a high-fidelity graph database. It normalizes entity identities and maps relationships between software artifacts so organizations can query the graph for audit, policy, and risk management outcomes.
Use cases
- find which of my applications are affected by a newly disclosed CVE
- aggregate SBOMs and security metadata from my whole organization into one queryable graph
- answer 'who depends on this library?' across my software estate
- audit the software supply chain for policy violations
- map relationships between software artifacts from SPDX and CycloneDX SBOMs
- check if any of my dependencies have known vulnerabilities or VEX statements
- query software supply chain metadata via GraphQL
- assess risk before approving a new open source dependency
When to choose
- you need a centralized, queryable graph of SBOMs, attestations, and vulnerability data across many projects
- you want to answer transitive dependency and vulnerability impact questions across your organization
- you need to correlate multiple metadata standards (SPDX, CycloneDX, in-toto, SLSA, VEX, OSV) in one place
- you are building supply chain policy, audit, or risk management workflows
When to avoid
- you just need to generate a single SBOM for one project rather than aggregate many
- you want a lightweight vulnerability scanner without graph ingestion infrastructure
- you cannot operate a multi-service stack (databases, message queue, collectors, GraphQL API)
- you need a turnkey commercial product with support rather than an actively developing project
