First Snyk Scan
Dependency scanning.
Overview
Snyk (and the family of similar tools: Dependabot, GitHub Advanced Security, Renovate) automates the work of comparing dependencies against known-CVE databases. The first integration is where supply-chain security moves from periodic manual audit into the routine PR review loop. The patterns established here apply to every repo the team owns.
- Dependency scanning. Lockfile diffed against vulnerability databases on every PR. Known CVEs surface before merge.
- License compliance. Non-permitted licenses caught at PR time. Legal review stops being a quarterly fire drill.
- Container scanning. Base-image and OS-package vulnerabilities. Catches the layer below the application.
- IaC scanning plus PR integration. Terraform, CloudFormation, and Kubernetes manifests checked for misconfiguration; auto-PRs for safe upgrades.
The approach
Three habits make Snyk integration produce real security rather than alert fatigue: CI-blocking thresholds tied to severity, auto-fix PRs for the upgrades that are safe, and explicit suppression with documented rationale for the ones that are not.
- CI integration on every PR. Snyk runs as a check. Regressions surface before merge, not after deploy.
- Severity thresholds. Block on high and critical; warn on medium; ignore informational. The thresholds match the team’s actual risk tolerance.
- Auto-fix PRs. Snyk opens upgrade PRs for safe versions. Remediation toil drops; remediation velocity rises.
- Documented suppressions plus policy.
.snykfile records each suppressed CVE with rationale and expiry; severity thresholds and SLAs documented next to the policy.
Why this compounds
Each scan deposits a little more supply-chain hygiene. The team learns which dependency families bring recurring CVEs; new repos start with the conventions already in place; auditors get evidence instead of promises.
- Supply-chain risk drops. Known CVEs caught at PR time stay out of production.
- License compliance becomes routine. Legal review happens at merge time, not before quarterly compliance reviews.
- Remediation velocity rises. Auto-fix PRs replace manual upgrade tickets.
- Year-one investment, year-two habit. First integration is heavy lift. By year two, every new repo ships with Snyk on day one.
