Conftest vs KloudSec IaC Security

Conftest is a free utility for testing structured configuration data, designed for use in CI environments. It uses the Open Policy Agent Rego language to express policies, then evaluates deny, violation, and warning rules within namespaces. Configuration can be read from individual files, directories, multiple files, or standard input. Supported inputs include Kubernetes-style YAML, JSON, HCL and HCL2, Dockerfiles, Terraform-related data, JSONnet, TOML, and XML. Results can be output as plaintext, JSON, TAP, table, JUnit, GitHub, Azure DevOps, or SARIF; the GitHub outputter can annotate test results in workflows. The `conftest verify` command runs policy unit tests. Policies can be pulled from HTTPS URLs, Git repositories, and OCI registries, or pushed to compatible OCI registries. Plugins extend the CLI, with downloads available from sources including OCI, Git, HTTP/HTTPS, Mercurial, and cloud storage. Pre-commit hooks support policy workflows, and integrations are documented for CircleCI, GitHub Actions, and Tekton. Conftest is available for Linux, macOS, and Windows.

KloudSec IaC Security scans Terraform and CloudFormation changes in pull requests to identify infrastructure misconfigurations before they merge. Its GitHub App runs scans automatically and reports findings as check runs and inline comments, without requiring CI pipeline changes. Teams can configure critical findings to stop a merge until they are resolved or explicitly acknowledged. The analysis considers relationships among resources, including network exposure, IAM permissions, encryption, and public access. Findings include AI-generated corrected Terraform blocks or CloudFormation snippets. The platform maps nine frameworks: CIS, PCI-DSS, SOC 2, ISO 27001, GDPR, HIPAA, NIST, DORA, and FFIEC. AWS is available, while Google Cloud Platform and Microsoft Azure are listed as coming soon. The Free plan allows five code scans per month and includes email support. A 14-day trial is offered without a credit card; paid plans start at $79 a month. KloudSec describes its intended users as startups, small and medium-sized businesses, and enterprises.
