+Checkov is a static code analysis tool for infrastructure-as-code.
+
+It scans cloud infrastructure provisioned using Terraform, Terraform plan, Cloudformation, Kubernetes, Dockerfile, Serverless or ARM Templates and detects security and compliance misconfigurations using graph-based scanning.
+
+At AOE we use checkov in CI/CD processes to get insights into our Terraform-Modules.
