In their own words
AWS Control Tower
AWS Control Tower sets up and governs multi-account AWS environments, bringing account structure, identity and policy enforcement under centralized management. It automates landing zone setup for new or existing AWS Organizations, including federated access and central backup integrations. Account Factory provisions accounts from configurable templates, with support for custom resources and requirements. Organizations can also use the Control Catalog on its own: it contains 750+ managed controls for security, cost, durability and operations. Controls can be detective, preventive or proactive; proactive controls use AWS CloudFormation Hooks to identify and block noncompliant deployments. Predefined integrations include AWS Organizations, IAM Identity Center, AWS Config, AWS Backup and AWS CloudTrail. AWS Marketplace also offers integrated third-party solutions. Control Tower has an API. The service has a free plan and no additional charge for Control Tower itself; underlying AWS services are billed based on usage, and optional controls or configured resources may add costs. The landing zone’s home Region cannot be changed after creation, and some detective and proactive controls do not work in every supported Region.
Kyverno
Kyverno is a free, open-source policy engine for defining and enforcing policy as code in Kubernetes. Its stable policy types can validate, mutate, generate or delete resources, and verify container image signatures and attestations. The Kyverno CLI can test policies against Kubernetes resource manifests in CI before they are applied to a live cluster. Documentation describes use with Helm, YAML manifests, GitHub Actions and GitOps tools such as ArgoCD. Kyverno is installed in a Kubernetes cluster; Helm is recommended for production, and YAML manifests are also available. A standard installation requires an admission controller, while background, reports and cleanup controllers are optional. Production installations should use high availability mode. The project supports CEL-based policy types and describes applying Kubernetes-style policies outside Kubernetes as part of its mission. Its webhooks default to fail-closed, so matching requests can fail if the API server cannot reach Kyverno. The project documents Cosign signatures for images and manifests, and lists CLI binaries for Linux, macOS and Windows.
