Keep scan and test evidence associated with the artifact it describes, and distinguish that evidence from an authorization decision.

Editorial update · October 6, 2026

Revised by TestifySec Editorial for the current technical-evidence focus. Unsupported authorization timelines, savings figures, and earlier AI security-plan offers have been removed. Existing article and section links are preserved.

Security checks often run well before an artifact reaches the team that must review it. When the result stays behind in a CI log, the reviewer has to reconstruct the relationship between the test, the source, and the deployed artifact.

 

Attestations can carry that relationship across systems. They support technical evidence collection; they do not automate an entire FedRAMP authorization.

 

## Container evidence needs an artifact binding

 

For a container scan, retain the image digest, scanner configuration, result, and producer identity. A report for an image tag may refer to different bytes later if the tag moves. Review the evidence for the exact image being accepted.

 

Container requirements also include matters outside a single scan, such as configuration, runtime operation, inventory, and response. Use the applicable FedRAMP requirements to determine scope rather than treating a scan as complete compliance.

 

## A signature needs a trust model

 

Signature verification checks integrity and attribution under the configured trust roots and identity constraints. A signer may still be compromised or dishonest. A signed artifact is not necessarily safe, and a signed test result is not necessarily accurate.

 

## An SBOM has a different role

 

An SBOM describes components and can support inventory and vulnerability analysis. It does not by itself establish which tests ran or which results were accepted. Combine component information with artifact-bound test evidence and the relevant review process.

 

## Capture once, review where it matters

 

Define a test, run it, retain the result, and connect it to the requirement it supports. A policy verifier can then evaluate that evidence at a configured decision point. The mapping should explain what the test does not cover and when the result becomes stale.

 

## Witness and the current product workflow

 

Use the [Witness documentation](https://witness.dev/) for the open-source workflow discussed in the original article. Use [CI/lock](https://www.testifysec.com/docs/cilock/getting-started/first-attestation) for TestifySec’s current capture workflow. The platform manages gates and technical evidence mappings; Pushgate checks configured requirements at the Git push boundary.

 

For FedRAMP 20x, consult the [current package guidance](https://www.fedramp.gov/2026/agencies/use/packages/20x/) and the [technical evidence overview](https://www.testifysec.com/blog/fedramp-20x-guide). A test can support a scoped requirement. Assessment, certification, and agency authorization decisions remain separate.
