What Is Software Provenance? A Complete Guide for Security Teams
Software provenance tracks the origin, history, and integrity of every component in your codebase. Learn why it matters for supply chain security and how to implement it.
Software provenance is the evidence trail behind your code
Software provenance records where code originated, who changed it, which dependencies it includes, and whether AI systems contributed to the final artifact. For security teams, that evidence turns vague supply-chain risk into an auditable record.
Why provenance matters now
AI-assisted development, open-source transitive dependencies, and faster release cycles make it harder to answer basic audit questions after the fact. Today ProvenanceOS scans public GitHub, GitLab, and Bitbucket repository URLs, checks npm and PyPI packages against OSV, computes an AI-origin score over a bounded source sample, records policy decisions, and can export a completed scan as CycloneDX. Automated policy enforcement and compliance-report export remain planned.
What teams should track first
Start with repository lineage, dependency source, and vulnerability evidence. A completed scan also includes an AI-origin score over a bounded sample and a recorded policy decision. Automated enforcement and compliance-report export are still planned, and those gaps still matter for SOC 2, EU AI Act, and internal governance reviews.
