Checkov vs Trivy in 2026: a field guide for Terraform teams

Who's writing this

We build audytx, a context-aware AWS Terraform and CloudFormation reviewer, so we're not neutral here. Two things keep this piece useful anyway: every statement about Checkov and Trivy cites the project's own README, checked 2026-10-01, and we say "use Checkov" and "use Trivy" below, without hedging, where each is the right call. audytx's own measured results are on the benchmark page, with the engine version and date beside each number.

Two tools, two missions

Checkov describes itself as "a static code analysis tool for infrastructure as code (IaC) and also a software composition analysis (SCA) tool for images and open source packages." Its README says "Over 1000 built-in policies cover security and compliance best practices for AWS, Azure and Google Cloud."

Trivy calls itself "a comprehensive and versatile security scanner." It scans container images, filesystems, remote git repositories, virtual machine images and Kubernetes, and looks for vulnerabilities, IaC misconfigurations, secrets, licenses and SBOM data. The tfsec README says that project's scanning effort moved to Trivy; we cover the migration on the tfsec page.

What differs

Don't read the columns as grades. Each tool does the job it was built for: Checkov casts a wide net over IaC, and Trivy puts many kinds of scanning into one binary.

Pick by scope — both are defensible

Choose Checkov when IaC policy coverage is the whole point: you want a wide checklist, you work across more than one cloud, or you scan several IaC formats in one pass.

Choose Trivy when consolidation is the point: one maintained tool for images, dependencies, SBOMs and IaC misconfiguration checks. If you are coming from tfsec, it is the path tfsec's own README points to.

Run both if image scanning and IaC policy live with different teams. They scan different things, so they sit side by side in a pipeline.

One more job, for AWS

Both tools check what is in the files they scan. audytx adds a different job for AWS Terraform and CloudFormation: it maps how your resources relate, keeps the findings that context supports, and lists each finding it sets aside with the reason written beside it. It does not replace either tool above. It is an AWS-focused review you can run beside whichever breadth tool you use. The mechanism is on the false-positives page; per-tool pages: vs Checkov · vs Trivy.
