Supplier and Manufacturer Reader Path

Use this path when a customer, assessor, auditor, or procurement team asks you to provide supply chain security evidence for a product, component, service, update, vulnerability response, or lifecycle event.

Decisions you probably need to make​

  • What evidence should we provide for a customer or buyer review?
  • Which product, version, component, service, or lifecycle stage does the evidence cover?
  • Which claims can we support with artifacts, records, or verification paths?
  • Which limitations, gaps, or exceptions need to be declared?
  • How should evidence be retained for later customer assurance, audit, renewal, or incident response?

Read these pages in order​

  1. Supplier Security Questions
    Understand the kinds of evidence customers may ask for.
  2. Evidence Maturity Model
    Distinguish assertions, documented processes, produced artifacts, verifiable artifacts, and lifecycle-retained evidence.
  3. Evidence Package Template
    Package evidence so reviewers can understand the decision, scope, source, verification path, gaps, and retention owner.
  4. Evidence Checklist
    Check whether your evidence is decision-ready before sending it.
  5. Worked Examples
    See realistic examples of weak, better, and stronger evidence packages.
  6. Technology Options
    Understand mechanisms that may help produce, protect, exchange, verify, or retain evidence.

What you should leave with​

After following this path, you should be able to produce:

  • a customer-ready evidence package;
  • scoped answers tied to product, component, service, version, or lifecycle stage;
  • declared limitations, gaps, and exceptions;
  • a retention plan for reusable customer, audit, renewal, or incident-response evidence;
  • a clear statement of what each artifact does and does not prove.

Evidence you should expect or produce​

Prepare evidence that names the artifact, owner, product or service scope, version, lifecycle stage, verification method, known gaps, exception status, and retention expectation. Make clear whether the evidence is a process description, produced artifact, verifiable artifact, or lifecycle-retained record.

Common weak answers​

  • "We have a secure process."
  • "We are certified."
  • "We can provide an SBOM."
  • "The issue has been fixed."

Stronger answers​

A stronger answer explains what evidence exists, what it applies to, who owns it, how a recipient can check it, how long it will remain available, and what limitations remain. It avoids overstating what a certificate, questionnaire, SBOM, signed update, or technology mechanism proves by itself.
