Harbor

Open Source

About Harbor

Harbor is an open source registry that secures artifacts with policies and role-based access control. Harbor is a CNCF Graduated project. It manages artifacts across cloud native compute platforms such as Kubernetes and Docker. It can be installed on any Kubernetes environment or on a system with Docker support.

Used for

Scanning images for vulnerabilities
Replicating content across many registries, including Harbor
Managing identity integration and role-based access control
Validating content signing

How to evaluate Artifact & Package Management

This is how the CIOPages Research Team evaluates this category. It is not an assessment of Harbor. It comes from our Container Registry & Artifact Management buyer guide.

25%

Supply-Chain Security & Provenance

Built-in vulnerability scanning (and whether it scans the binary or just the manifest), Cosign/Notation signing with content-trust enforcement, SBOM generation and storage (CycloneDX / SPDX), SLSA-style build provenance and attestation, and proactive quarantine of malicious or typosquatted dependencies before they enter

20%

Artifact & Format Breadth

Container/OCI plus the language ecosystems you actually use (npm, Maven/Gradle, PyPI, NuGet, RubyGems, Go, Helm, Debian/RPM); OCI-artifact support for non-image content; remote/proxy and virtual (aggregating) repositories; and whether one platform covers everything or you stitch several together

15%

Access Control, Multi-Tenancy & Governance

SSO/SAML/OIDC and SCIM, fine-grained and project-scoped RBAC, immutable tags and retention/cleanup policies, environment-promotion gates (dev→staging→prod), tamper-evident audit logging, and compliance posture (SOC 2 Type II, ISO 27001, FedRAMP where relevant)

15%

Distribution, Performance & Availability

Pull-through caching of upstream registries, geo-replication / edge distribution to your runtime regions, deduplication and storage efficiency, high availability and DR, and pull latency and throughput under CI burst and large-image load

15%

CI/CD & Platform Integration

Native hooks into your CI (GitHub Actions, GitLab, Jenkins, Argo), Kubernetes admission-control and OIDC-based keyless auth, webhooks/events, a complete REST API and Terraform provider for IaC, and cloud IAM integration if you live in one provider

10%

Operations & Cost Model

Self-managed vs. SaaS effort, upgrade and HA burden for self-hosted options, and how the meter works — per-user, storage, egress/data-transfer, or per-scan — because the unit of billing, not the headline rate, decides what you pay as pulls and image counts grow
