Who is Chainguard?
Chainguard is a software supply chain security company that provides tools, managed services, and hardened container images to help organizations build, verify, and run cloud-native workloads with provenance and policy controls.
- Hardened, minimal container images and base images for cloud-native workloads (container security)
- Build, signing, and provenance tooling aligned to software supply chain security frameworks (DevSecOps)
- Policy-based controls for verifying software artifacts before deployment (governance and compliance)
- Support for Software Bill of Materials (SBOM) generation and attestation to improve package and dependency transparency (software composition analysis)
- Professional services and expertise around secure build pipelines and software supply chain hardening (security services)

More About Chainguard
Chainguard focuses on software supply chain security for organizations that operate containerized and cloud-native workloads. Its offerings are used by enterprises that need to attest to the origin, integrity, and contents of software artifacts across build, test, and runtime environments. The company emphasizes verifiable builds, provenance metadata, and policy enforcement so that technical teams can control which artifacts are allowed into production.
A core part of Chainguard’s portfolio is hardened and minimal container images (container security). These images are designed to reduce the package footprint and exposed attack surface while maintaining compatibility with common application stacks and runtimes used in Kubernetes and other container orchestration platforms. Enterprises often use these images as base layers for applications that must comply with internal security baselines or external regulatory frameworks.
Chainguard also provides tooling for artifact signing, provenance capture, and verification aligned with supply chain security practices (DevSecOps). This includes support for software Bill of Materials (BOM) (SBOM) generation and attestation formats widely referenced in the ecosystem. The tooling is designed to integrate into existing Continuous Integration and Continuous Deployment (CI/CD) systems so that build pipelines can emit verifiable metadata about source, dependencies, and build steps.
Policy-based controls are another focus area (governance and compliance). Chainguard’s approach allows platform and security teams to define policies that gate deployments based on criteria such as signature validity, provenance completeness, or SBOM presence. These controls are typically integrated with Kubernetes admission workflows or other deployment stages, enabling only artifacts that meet policy to progress to production.
From a technology perspective, Chainguard aligns with established industry efforts around container security, artifact signing, and supply chain integrity, and it interoperates with common cloud-native platforms, registries, and orchestration frameworks. The company addresses requirements that arise from frameworks and guidance related to software Supply Chain Risk Management (SCRM), helping organizations document and enforce controls around software origin and composition.
In enterprise environments, Chainguard is generally categorized under container security, software supply chain security, DevSecOps tooling, and security services. Its offerings are used by platform engineering teams, security engineering groups, and compliance-focused stakeholders who need consistent baselines for container images, verifiable metadata for software artifacts, and enforceable policies across build and deployment workflows.
