Chainguard is a cybersecurity company that specializes in securing the open-source software supply chain. Founded in 2021 by the creators of foundational open-source projects like Sigstore and Kubernetes, the company provides hardened, minimal, and secure-by-default container images (Chainguard Containers), language libraries, and virtual machines. By delivering artifacts with significantly reduced attack surfaces and near-zero CVEs (Common Vulnerabilities and Exposures), Chainguard helps engineering and security teams safely accelerate software development. Their solutions enable organizations to simplify continuous compliance for stringent standards like FedRAMP, SOC 2, and PCI DSS, while mitigating the risk of software supply chain attacks.
