Executed + Trivy Vulnerability Scanner Collector

✓ Guardrail ↓ Collector Stable Security And Compliance

Enforce Executed using data collected by Trivy Vulnerability Scanner Collector. Automatically check security and compliance standards on every PR.

Guardrail: Verifies that SCA scanning was executed on the component. Fails if no scanner has written to .sca.

Data Source: Automatically scans repository dependencies for known CVEs using Trivy. Supports Go, Node.js, Python, Java, Rust, and many other ecosystems. Writes normalized vulnerability data to .sca for use with the SCA policy. No secrets or vendor accounts required.

How Trivy Vulnerability Scanner Collector Powers This Guardrail

The Trivy Vulnerability Scanner Collector gathers metadata from your security systems. This data flows into Lunar's Component JSON, where the Executed guardrail evaluates it against your standards.

When enabled, this check runs automatically on every PR and in AI coding workflows, providing real-time enforcement with actionable feedback.

What Trivy Vulnerability Scanner Collector Collects

This collector gathers the following data that the Executed guardrail evaluates.

Collector code

`auto`

Auto-scans the repository filesystem for dependency vulnerabilities using Trivy. Writes normalized findings to .sca with severity counts, CVE IDs, affected packages, and fix versions.

Collector ci-after-command

`cicd`

Detects Trivy executions in CI pipelines. Captures the command, version, and input arguments for audit and compliance tracking.

Example Data Flow

Here's an example of the data that Trivy Vulnerability Scanner Collector writes to the Component JSON, which Executed then evaluates.
