Trivy
Security scanner for container images, file systems, Git repositories, and Kubernetes configurations to detect CVEs.
Technical Architecture & Overview
Trivy is an open-source security scanner from Aqua Security. It scans container images, code repositories, virtual machine disks, and Kubernetes clusters for known CVEs, misconfigurations, exposed secrets, and license issues. Aqua offers a premium version of Trivy in its commercial container security product.
Targeted Technical Use Cases
Scanning Docker images and Kubernetes manifests in CI/CD pipelines and container registries.
Evaluation & Trade-offs
Core Strengths
- +Fast scanning engine with vulnerability databases built as frequently as every 6 hours.
- +Covers OS packages (Alpine, Debian, RHEL) and language dependencies (npm, pip, Go, cargo).
- +Integrates directly into GitHub Actions, GitLab CI, Harbor, and VS Code.
Trade-Offs & Limitations
- -Focuses on known CVEs and static configs; does not perform runtime behavior monitoring.
- -Reports can be large without proper severity filtering.
Defensive Security Application
Preventing vulnerable container images and misconfigured cloud manifests from reaching production clusters.
