Securing container images is a foundational part of protecting modern cloud‑native applications. Teams need a reliable way to ensure that the images moving through their pipelines are authentic, untampered, and produced by trusted publishers.
We’re excited to share an updated approach that combines the Notary Project, the CNCF standard for signing and verifying OCI artifacts, with Artifact Signing—formerly Trusted Signing—which is now generally available as a managed signing service.
The Notary Project provides an open, interoperable framework for signing and verification across container images and other OCI artifacts, while Notary Project tools like Notation and Ratify enable enforcement in CI/CD pipelines and Kubernetes environments. Artifact Signing complements this by removing the operational complexity of certificate management through short‑lived certificates, verified Azure identities, and role‑based access control, without changing the underlying standards.
If you previously explored container image signing using Trusted Signing, the core workflows remain unchanged. As Artifact Signing reaches GA, customers will see updated terminology across documentation and tooling, while existing Notary Project–based integrations continue to work without disruption.
Together, Notary Project and Artifact Signing make it easier for teams to adopt image signing as a scalable platform capability—helping ensure that only trusted artifacts move from build to deployment with confidence.
