Evidence that supply chain governance works is a set of records produced by normal operation: a signed charter, a decision log, a current inventory, an exception register with expiry dates, review minutes and pipeline results. If you keep these as you go, an audit becomes a retrieval task.
Evidence versus documents
A policy shows intent. Evidence shows the policy ran. Ask of each record: who made it, when, and would it exist if nobody were auditing? Records created as a side effect of work are more convincing than documents written for the audit.
A starter evidence list
| Governance element | Evidence to keep |
|---|---|
| Program agreed by stakeholders (CSF GV.SC-01) | Charter and policy with approval and date |
| Roles established (GV.SC-02) | Owner list, decision rights matrix |
| Integration with risk management (GV.SC-03) | Entries in the main risk register |
| Suppliers prioritized (GV.SC-04) | Tiered supplier and component list |
| Requirements in contracts (GV.SC-05) | Standard security schedule, sample executed contracts |
| Due diligence before adoption (GV.SC-06) | Intake records and automated check results |
| Monitoring over the relationship (GV.SC-07) | Scan history, advisory alerts, review notes |
| Incident planning with suppliers (GV.SC-08) | Contact list, tabletop notes |
| Offboarding (GV.SC-10) | Exit checklists |
The GV.SC identifiers come from NIST CSF 2.0. The Framework is voluntary and not a certification, so this table is a way to organize records, not a claim of conformance.
Records that tend to be asked for
- Decision log. Each entry has what, who, when, why and a review date.
- Exception register. Owner, scope, compensating control, approval, expiry and renewals. See exception audit trail.
- Inventory snapshots. SBOMs for releases, with timestamps. The NTIA minimum elements include a timestamp as a data field, which helps show when each was produced.
- Review minutes. Short, with attendees, decisions and follow-ups.
- Policy change history. Versions, approvers and reasons.
- Pipeline results. Evidence that checks ran on changes, including blocked changes.
How to keep evidence cheaply
- Store records in one agreed place with consistent names.
- Let tools write the records. Pipelines and registers can log automatically.
- Date everything and record approvers.
- Run a quarterly spot check: pick one release and trace its evidence end to end.
- Fix gaps in the process, not by backfilling documents. Backfilled evidence is easy to spot and should not be created.
What not to claim
Do not describe your program as certified or compliant with a framework unless an accredited or authorized party has said so. Say what you do and show the records. Questionnaire answers should be specific and true.
Try it yourself
Click through it at your own pace, or open it full screen. Follow how a control connects to evidence that exists in the system.
Safeguard's compliance and evidence automation, SBOM and dependency scanning, and policies and gates produce several of these records as scans and checks run.
Quick check
How long should we keep evidence?
Follow your contracts, regulators and internal retention policy. Decide it once and write it down.
Is a screenshot enough?
Usually a system record with a timestamp is stronger than a screenshot.
