audytx vs Trivy

audytx analyzes AWS infrastructure code and Terraform pull requests, presenting security and cost findings in GitHub and to coding agents. Its deterministic, non-AI engine models resource relationships such as invocation topology, encryption chains, network exposure, resource lifetimes, and IAM trust graphs. The maker lists 303 AWS Terraform checks and 27 cross-resource reasoning axes. A GitHub App posts pull-request digests, inline review, and SARIF, using read-only contents permission while writing comments, reviews, statuses, and SARIF uploads. An optional GitHub Actions step uploads a resolved Terraform plan over OIDC without shared secrets. A hosted MCP server exposes the engine to Claude Code, Cursor, and Codex; autofix applies line-anchored changes and rescans for up to three passes. AWS, Terraform, and CloudFormation are supported in stated hosted workflows. Free includes 100 scans monthly; Plus costs $20 a month and Pro $100 a month.

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.
