Software Supply Chain Attestation
We run critical infrastructure on software we cannot reliably inventory or verify, and we still treat build provenance as optional metadata.
The Stakes
Software supply chain compromise is a systems-level threat. A single poisoned dependency can cascade across governments, hospitals, and industrial control systems. Attestation infrastructure converts trust from “brand and hope” to verifiable facts.
Headline evidence
- •Executive Order 14028 defines a Software Bill of Materials (SBOM) as a formal record of components and supply chain relationships used to build software. [1]
- •NIST’s Secure Software Development Framework (SSDF) recommends a core set of secure software development practices that acquirers can use in procurement and governance. [2]
- •The SLSA specification defines levels and attestation formats, including provenance, to incrementally improve software supply chain security. [3]
Neglectedness
Why it stays neglected
The ecosystem is fragmented: open-source maintainers, vendors, cloud platforms, and buyers all control different parts. Generating SBOMs is easier than making them actionable. Procurement language is inconsistent. Many organizations lack the policy engines and operational maturity to enforce provenance at deployment time.
Tractability
High enough to win. Standards exist, and regulators are pushing. Tooling for build signing, provenance, and policy gating is rapidly improving. AI helps automate SBOM analysis, vulnerability prioritization, and compliance evidence generation. The hard part is end-to-end adoption and interoperability.
Startup surfaces
- •SBOM ingestion and “action layer”: risk scoring, policy enforcement, and remediation workflows
- •Build provenance and artifact signing integrated into common CI/CD stacks
- Procurement compliance platforms:SSDF mappings, attestations, and audit-ready evidence
- Dependency graph intelligence:exploit likelihood, blast radius, and patch prioritization
- •Managed “secure build pipeline” services for mid-market and critical infrastructure vendors
