CFRipper vs Trivy

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.

Trivy is a free, Apache-2.0-licensed scanner for code repositories, binary artifacts, container images, and Kubernetes clusters. Its scanners cover vulnerabilities, infrastructure-as-code misconfigurations, secrets, and licenses, and it can generate software bills of materials. Vulnerability checks include operating-system and language-specific packages, some non-packaged software, and Kubernetes components. Configuration checks cover Docker, Kubernetes, Terraform, and CloudFormation files, and users can write custom checks. Trivy supports ecosystems including Ruby, Python, PHP, Node.js, .NET, Java, Go, Rust, C/C++, Elixir, Dart, Swift, Julia, and operating-system packages. It can run as a CI/CD binary without middleware or database dependencies and can be used in air-gapped environments. Installation options include container images, release binaries, package repositories, Homebrew, and Windows downloads; official integrations include Azure DevOps and GitHub Actions. Results can be exported as JUnit XML, SARIF, and ASFF. The vulnerability scanner documentation says third-party or self-compiled packages and binaries are unsupported, and the scanner may skip third-party packages. Trivy automatically fetches and maintains the security databases it needs for scans. The project is identified as Go software under the Apache-2.0 License; Aqua Security is listed as founded in 2015 with headquarters in Boston and Ramat Gan.
