Trivy vs Grype: Which Vulnerability Scanner for CI?
By Kaveh Alemi·Latchkey
Both are fast open-source vulnerability scanners; Trivy is broader (images, IaC, secrets), Grype is focused and pairs with Syft for SBOMs.
Trivy (from Aqua) scans container images, filesystems, and repos for vulnerabilities, plus misconfigurations (IaC), secrets, and licenses. Grype (from Anchore) is a focused vulnerability scanner that pairs with Syft for SBOM generation, emphasizing accuracy and SBOM-driven workflows.

All-in-one security gate
Focused vuln/SBOM workflow
In CI
Trivy is a strong all-in-one gate: one tool scans images for CVEs and also checks IaC misconfigurations, secrets, and licenses, which simplifies the pipeline. Grype focuses on vulnerability detection and shines in SBOM-centric workflows with Syft - generate an SBOM once, scan it, and reuse it across stages. Both are fast, free, and CI-friendly, and both can fail the build on severity thresholds.
Choosing for pipelines
Want one tool covering vulns plus IaC/secrets/licenses: Trivy. Want a focused vuln scanner in an SBOM-first workflow (Syft + Grype): Grype. Pin the database/version and set severity thresholds in CI on either.
Benchmark on your repository before choosing
Build-tool benchmarks published by vendors use repositories chosen to show a difference. Yours is the only one that matters, and both a cold and a warm measurement are needed because CI mostly runs cold.
Terminal
# cold: no cache, the CI condition
rm -rf node_modules/.cache dist && time <tool> build
# warm: the local development condition
time <tool> build
# and the one people forget: incremental after a one-line change
echo "// touch" >> src/index.ts && time <tool> build
The verdict
Want an all-in-one scanner (vulns + IaC + secrets): Trivy. Want a focused, SBOM-driven vuln scanner with Syft: Grype. Both make solid CI gates - set severity thresholds and pin versions.
