Provenance explains how an artifact was built and which systems touched it. Artifact integrity proves the shipped file still matches the expected output from that build. You need both. Provenance tells you whether the path was trustworthy, while integrity tells you whether the output was altered after the fact.
How provenance and artifact integrity differ
Provenance asks where an artifact came from, who built it, what pipeline produced it, and what systems or inputs were involved along the way. Artifact integrity asks whether the artifact you have now is still the exact output you expected from that build. The distinction matters because a trustworthy build path does not guarantee a tamper-free file, and an untampered file does not prove the build path was trustworthy.
Think of provenance as the story of creation and artifact integrity as the state of the delivered object. Provenance is about traceability and trust in the process that produced the artifact, while integrity is about detecting alteration after release, transfer, or storage. SLSA is the clearest external reference for keeping those ideas separate while still treating them as complementary controls in software supply chain security.
In practice, teams often need provenance metadata plus a verification mechanism such as a digest, signature, or attestation check. Provenance answers whether the artifact can be linked back to a controlled build process; integrity answers whether the bytes match what that process produced. That is why both checks appear together in modern software release and consumption workflows, including secure supply chain guidance from NIST SSDF (SP 800-218) and the broader supply chain ecosystem around OpenSSF.
Why you should not treat one as a substitute for the other
Provenance alone can tell you that a build came from an approved path, but it cannot tell you whether the artifact was swapped after signing, mirrored incorrectly, or corrupted in transit. Integrity alone can tell you the file matches a known checksum or signature, but it cannot tell you whether the build process was compromised, the inputs were malicious, or the artifact was produced in an untrusted environment.
The practical failure mode is false confidence. A team may verify provenance and assume the release is safe, even though a storage layer, distribution channel, or deployment step altered the payload. Or the team may verify integrity and assume the object is safe, even though the build itself embedded malicious code or pulled in an untrusted dependency. Supply chain controls work best when the trust chain for creation and the tamper check for delivery are both present.
That separation is also why security programs pair build-time controls with post-build verification. The build system establishes origin and traceability, while the consuming system or release gate checks that the artifact has not changed since it was produced. NIST SP 800-53 Rev. 5 reinforces this pattern through integrity, configuration management, and audit controls that support both trust in the process and trust in the delivered object.
How practitioners should use both in a release workflow
Use provenance when you need to answer, “Can I trust how this was built?” Use artifact integrity when you need to answer, “Can I trust that this is still the same thing?” The right operational pattern is to collect provenance at build time, then verify integrity at every boundary where the artifact is stored, transferred, promoted, or deployed.
What to verify: Confirm that provenance records identify the build source, build identity, and relevant dependencies, then confirm that the delivered artifact matches the expected digest or signed attestation before release promotion. If the two disagree, treat it as a release-blocking event, not a routine exception.
Decision rule: If you must choose where to invest first, start with provenance for high-value or frequently rebuilt software, because it helps you prove trustworthy origin and narrow the blast radius of upstream compromise; then add integrity checks at distribution and deployment points to catch alteration after build.
Practitioner takeaway: Provenance reduces uncertainty about origin, while artifact integrity reduces uncertainty about tampering, and mature delivery pipelines need both to answer the full trust question.

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
SLSA, NIST SP 800-53 Rev 5 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| SLSA | Supply chain levels for software artifacts | Directly addresses build provenance and artifact integrity in software supply chains. |
| Recommendation — Adopt SLSA-aligned controls to preserve build provenance and verify artifact integrity before release. | ||
| NIST SP 800-53 Rev 5 | SI-7 — Software, Firmware, and Information Integrity | Covers integrity verification for delivered software and related artifacts. |
| CM-3 — Configuration Change Control | Supports controlled build and release paths that provenance depends on. | |
| AU-2 — Event Logging | Supports traceability of build and release actions needed for provenance evidence. | |
| Recommendation — Apply SI-7 to verify artifacts have not been altered before promotion or deployment. Use CM-3 to control changes across build and release pipelines. Log build and release events so provenance can be traced and audited. | ||
| OWASP ASVS | V15 — Secure Coding and Architecture | Supports build and release integrity expectations for application artifacts. |
| Recommendation — Embed integrity checks in the software lifecycle to prevent unauthorized artifact changes. | ||
