The models' case: Best overall for mixed-format enterprises: universal repositories, dependency firewalling, recursive vulnerability and license analysis, SBOMs, signed evidence, and. The models' main caveat: Its strongest security workflow requires costly add-ons and substantial administration, so it is excessive for small teams. The strongest alternative is Harbor — The premier open-source OCI registry providing self-hosted data control, native vulnerability scanning via Trivy, immutable image tags, and.
