It also ensures that the images are scanned and free from vulnerabilities before signing them as trusted. It secures artifacts using policies and role-based access control. Harbor Container Image Registry is a free and open-source enterprise-class container registry used to store and distribute container images. Multiple authentication systems put measures in place to verify the container images.

Private container registries are preferred since they allow the organization to access the images internally in a more secure way. The most popular Private Registries are Google Container Registry, Amazon Elastic Container Registry (ECR), and the Azure Container Registry. They can be hosted remotely or o-premise.
