CFRipper vs KloudSec IaC Security

CFRipper is a free, open-source Python library and command-line security analyzer for AWS CloudFormation templates. It examines template files to help keep vulnerable infrastructure from reaching production. The CLI accepts templates as arguments and can return text or JSON findings, with an option to save results in an output folder. Example findings include wildcard principals and IAM role policies that grant excessive permissions. Rules can be configured with a rules file and filters folder, and users can add plugins for their own compliance checks. Documented exit codes distinguish successful scans, scanning errors, invalid templates, and unhandled exceptions. CFRipper runs on Linux, macOS, Windows, or as self-hosted software. The project uses uv for dependencies, provides installation instructions for those operating systems, and is distributed under the Apache License 2.0. Its analysis scope is CloudFormation; Terraform and Kubernetes are not supported.

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.
