DryRun Security IaC Security vs Kyverno

DryRun Security IaC Security scans infrastructure-as-code changes for security risks by analyzing infrastructure and application code together. It covers Terraform, Kubernetes, and other IaC, with checks for overly permissive IAM policies, publicly exposed resources, insecure defaults, and subdomain takeover risks. Scans run in pull requests and provide guidance during infrastructure design. Teams can write natural-language guardrails for public access, permitted cloud regions, approved resource types, and organization-specific requirements; the Custom Policy Agent enforces them on changes. Terraform findings can appear as pull-request comments and Risk Register entries containing the affected resource, risk description, and remediation guidance. Listed integrations include Claude Code, Claude Desktop, Codex, Cursor, GitHub, GitLab, and Slack. The SaaS service supports GitHub.com personal, organization, and Enterprise Cloud repositories, plus GitLab SaaS; custom instances and other source-control systems require contacting DryRun. DryRun says it uses private models, sends no data to public AI systems, stores minimal metadata and findings, and allows code-access revocation through repository permissions. Pricing is on request, aligned with team size, and a free trial is available.

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.
