Trivy

Trivy is a free, open-source scanner for vulnerabilities, secrets, licenses and infrastructure misconfigurations across software and Kubernetes. It suits teams that want security checks in development pipelines or self-hosted environments. Its range of scan types and deployment options is useful, but package blind spots and plugin risks make careful configuration important.

Overview

Trivy covers repositories, binary artifacts, container images and Kubernetes clusters, and can generate software bills of materials. Its vulnerability scanner detects known issues in operating-system and language packages, some non-packaged software, and Kubernetes components. That breadth makes it relevant beyond container scanning, though it is not a complete inventory of every binary: third-party and self-compiled packages and binaries are unsupported, and third-party packages may be skipped.

The Go project uses the Apache-2.0 license. Trivy maintains the security databases it needs by fetching them automatically. It can run as a CI/CD binary without middleware or database dependencies and supports air-gapped environments, which suits teams with isolated infrastructure or a preference for a lightweight self-hosted deployment.

Key features

Multiple scanner types

Alongside vulnerability scanning, Trivy includes secret, license and infrastructure-as-code scanners. Built-in configuration checks cover Docker, Kubernetes, Terraform and CloudFormation files, and teams can write custom checks. This gives development and security teams several kinds of checks in one tool; package coverage remains the important caveat for vulnerability findings.

Reporting and integrations

Trivy generates SBOMs and can export results in formats including JUnit XML, SARIF and AWS Security Finding Format. Those formats can fit existing reporting and security workflows. Official pipeline integrations include a GitHub Action and Azure DevOps Pipelines Task, while the ecosystem also includes a VS Code plugin. The documentation distinguishes core-team-supported official integrations from community integrations, whose security and maintenance are not guaranteed.

Trivy Operator can be installed in a Kubernetes cluster to scan workloads and the cluster continuously. That is a useful option for teams managing Kubernetes in-cluster, rather than a substitute for checking software outside that environment.

Installation and security trade-offs

Official installation options include container images, release binaries, package repositories, Homebrew and Windows downloads. Supported platforms include Linux, macOS, Windows and FreeBSD, alongside self-hosted deployment. The broad choice makes it practical to fit into varied environments. Plugins need more caution: they run with the user's permissions, are not sandboxed, and publicly available plugins are not audited for security.

Pricing

Trivy's plan costs free. It is an Apache-2.0-licensed open-source scanner, with no paid tier or free trial. That makes it a strong fit for teams seeking scanning without a software fee, especially those able to operate it themselves. There are no published seat or scan quotas to weigh, but the free plan does not remove the need to account for its package-coverage limits or evaluate third-party plugins carefully.

Platforms

Trivy supports Linux, macOS, Windows and FreeBSD, and is also distributed as an official container image. It can be deployed self-hosted as a binary or in a Kubernetes cluster through Trivy Operator. This range is useful for teams spanning developer machines, build pipelines and Kubernetes, while air-gapped support accommodates isolated environments.

Who it's for

Trivy is a good choice for development and security teams that want one free tool for vulnerability, secret, license and configuration checks, SBOM generation, and pipeline integration. It is particularly suitable when self-hosted operation, air-gapped use or Kubernetes scanning matters. Teams whose software depends on third-party or self-compiled packages should not treat its vulnerability results as comprehensive. Those considering plugins should also account for the fact that they run unsandboxed with user permissions.

Pros and cons

• Pros: Free and Apache-2.0 licensed, with vulnerability, secret, license and misconfiguration scanning plus SBOM generation in one tool.
• Pros: Runs without middleware or database dependencies, supports air-gapped environments, and offers official integrations for GitHub Actions and Azure DevOps Pipelines.
• Pros: Trivy Operator supports automatic, continuous scanning of Kubernetes workloads and the cluster.
• Cons: Third-party and self-compiled packages and binaries are unsupported, and third-party packages may be skipped, limiting vulnerability coverage.
• Cons: Plugins are not sandboxed, inherit user permissions and are not audited for security.
• Cons: Community integrations are not guaranteed to be secure or maintained.

Alternatives

Grype is another free, Apache-2.0-licensed open-source vulnerability scanner; choose it if you want a focused vulnerability-scanning alternative to Trivy's broader scanner set.

Kubescape offers an Apache 2.0-licensed, self-hosted open-source option with a CLI and Kubernetes operator; consider it when those are the capabilities you want to compare.

Intruder has a free plan capped at five infrastructure targets, excludes web apps, and includes weekly external scans and one connected cloud account; choose it if those limits and its infrastructure focus suit your needs.

Mondoo CSPM has free open-source tools for cloud, Kubernetes, OS, SaaS and API scanning, with a Kubernetes operator and extensible provider system; consider it for that broader stated scan scope.

Prowler Cloud offers a 15-day free trial with no cloud account limit and access to every check and compliance framework; it may suit a time-limited evaluation of those capabilities.

Cy5 Cloud-Native Vulnerability Management is an alternative with web access and three named plans.

Qualys TotalCloud offers a free license with limited API calls for control evaluation; consider it if that evaluation use is the priority.

RapidFort offers five curated near-zero-CVE images from a limited catalog, with daily rebuilds and patching; choose it if ready-to-use container images are your focus rather than broad scanning.

Compare more options in Cloud Vulnerability Scanners, Container Image Scanning Tools, Container Security Software, Infrastructure as Code Security Software and Software Composition Analysis Software.

Verdict

Choose Trivy if you want a free, self-hosted scanner that spans several security checks, generates SBOMs and can fit into CI/CD or Kubernetes workflows. Its strongest case is breadth without a software fee or infrastructure dependencies. Look elsewhere, or supplement its coverage, if you need dependable vulnerability detection for third-party or self-compiled packages; use plugins only when you accept their unsandboxed security model.
