In their own words
CGPulse
CGPulse scans Azure and AWS resources for misconfigurations and tracks cloud compliance against policy rules and frameworks. Its coverage lists 621 rules across 19 frameworks, including Azure, AWS and cross-cloud policies. Scanning uses read-only access and does not modify cloud resources. Users can review supported fixes before applying them; fixes marked dangerous require a warning and confirmation. The service can generate Terraform, Bicep and CLI remediation templates, while a YAML editor lets users create custom rules. It also provides a REST API and an MCP server for AI assistants including Claude and Copilot. CGPulse is available on the web and through an API, with Free, Team and Business plans. Free costs nothing and allows two cloud accounts and 10 scans monthly; Team costs €99 a month and Business costs €299 a month. Team and Business list a 7-day free trial. CGPulse describes itself as a posture assessment tool, not a certified compliance audit.
Open Policy Agent Gatekeeper
Open Policy Agent Gatekeeper is a free, open-source Kubernetes policy controller for Linux and self-hosted deployments. It runs as a validating and mutating webhook, enforcing CRD-based policies evaluated by Open Policy Agent. Validation constraints can deny requests, warn, run in dry-run mode or report violations without changing resources. Mutation policies can alter matching resources during admission before validation checks the final object. An audit function periodically evaluates existing cluster resources against constraints to identify pre-existing misconfigurations. The project includes an extensible policy library with parameterized examples, and provider connections to external data such as image registries and directory services. Named integrations or backed services include Azure Policy for Kubernetes, Google Kubernetes Engine Policy Controller, Rancher, AWS EKS Blueprints and Alibaba Cloud. Installation options include prebuilt, development or locally built images and Helm. Gatekeeper requires Kubernetes resources introduced in version 1.16 and cluster-admin permissions for installation. The gator CLI is documented as beta from version 3.11.
