Docker best practices for Node.js developers in 2026
Multi-stage builds can cut a Node.js image from 1GB+ down to under 150MB — but most teams still ship dev dependencies, root shells, and unscanned base layers to production.

A balanced 2026 comparison of the leading container image scanners — Trivy, Grype, Snyk Container, Prisma Cloud, Wiz, and Docker Scout — with an honest look at where each fits and how Safeguard compares.
Scanning container images in CI/CD pipelines
Where to put container image scanning in your CI/CD pipeline, what it actually catches, and how to stop CVE floods from blocking every build.
Container image scanning: how it works and best tools
A practical guide to container image scanning: how layer-by-layer CVE detection works, how Trivy stacks up, and where Safeguard adds deeper coverage.
SBOM for Containers: 2026 Buyer's Guide
How to generate, manage, and act on SBOMs for containers in 2026: tool comparison, layered SBOMs, signing, and runtime drift detection.
Container Image Supply Chain: From Dockerfile to Production
Every container pulled in production is a trust decision. Here's how to secure the chain from base image selection through Dockerfile to admission control.
What is Container Security
Container security protects images, runtimes, orchestration, and hosts. Here's what it covers, why 87% of images ship with critical CVEs, and how to fix it.
What is Container Registry Security
Container registries are one of the highest-leverage attack points in the software supply chain. Here's what actually secures one, with real incidents and numbers.
State of Container Security 2026: Survey Summary
A survey-style summary of container security in 2026: what production teams actually ship, where image security stands, and which runtime controls moved the needle.
Best Container Security Tools in 2026
Image scanners, runtime sensors, and Kubernetes posture tools each catch different failures. Here is how the leading options compare in 2026 — and how to pick a stack without buying three overlapping scanners.
Docker Vulnerability Scanners: What They Catch and Miss
Image scanners are excellent at matching OS packages and language dependencies against CVE databases — and structurally blind to config flaws, runtime behavior, and code you compiled yourself. Where the line sits.
Docker Scanners: Comparing the Image-Scanning Options
A docker scanner has to check three separate layers — base OS packages, application dependencies, and the Dockerfile itself — and most tools are genuinely strong at only one or two.
