In their own words
KICS
KICS is a free, open-source static analysis solution powered by Checkmarx. It scans Infrastructure as Code for security vulnerabilities, compliance issues, and configuration mistakes across Terraform, Kubernetes, Docker, AWS CloudFormation, Ansible, Helm, Google Deployment Manager, AWS SAM, Microsoft ARM, Azure Blueprints, OpenAPI, Pulumi, Crossplane, Knative, and Serverless Framework files. Its security queries can be edited, extended, or supplemented with new queries, using OPA Rego policy language. Documented CI and delivery integrations include GitHub Actions, GitLab CI, Jenkins, Azure Pipelines, CircleCI, Bitbucket Pipelines, Terraform Cloud, AWS CodeBuild, pre-commit hooks, and others. A Visual Studio Code extension can scan automatically. KICS runs as a Docker image, from source, or through downloadable Linux, Windows, and macOS releases. Reports can be exported as JSON, SARIF, GitLab SAST, JUnit, HTML, PDF, CycloneDX, ASFF, or CSV. Terraform functions and environment variables are unsupported, and unofficial or custom Terraform modules are not supported.
Sonobuoy
Sonobuoy is a free, open-source diagnostic tool for examining Kubernetes cluster state with non-destructive configuration tests. It can check a cluster against official Kubernetes specifications and produce diagnostics for troublesome workloads. Teams can build plugins for additional tests and data collection. Its default plugins run Kubernetes end-to-end tests and gather systemd logs; community options include CIS Benchmarks, Kube-hunter, Who-can, Cluster-Inventory, and Reliability Scanner. It is cluster agnostic and officially supports the latest three minor Kubernetes versions. Beginning with version 0.20, it supports Kubernetes 1.17 or later. Sonobuoy can run end-to-end tests with custom registries in air-gapped deployments. It requires an active Kubernetes cluster and an admin kubeconfig, and can be installed from binary releases or through Homebrew on macOS. The project provides community support through GitHub. Its documentation warns that default settings need explicit hardening, and notes that some logging and retrieval commands can fail on Docker Desktop Kubernetes.
