Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
A plain explanation of what the "new tag scanned" event actually means in registries like GHCR, ECR, and Docker Hub, and what to do when it flags a vulnerability.
Docker images do not have a special file extension. When you save one it is a .tar archive. Here is what is inside, and how the OCI layout is structured.
How to wire container image vulnerability scanning into your CI pipeline so builds fail on real risk instead of shipping unscanned images to production.

What Docker is actually used for in real teams: packaging apps, consistent environments, and shipping to production, plus the security angles that come with containers.
Gartner's container security research correctly frames the shift toward CNAPP consolidation, but its category boundaries often lag how teams actually operate scanning day to day.
A Docker container is a lightweight, isolated unit that packages an app with everything it needs to run — here's what that actually means under the hood and why it matters for security.
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.
Open-source base images change your patch cadence, your license exposure, and your provenance story — here's what OSS container security actually adds on top of standard image hardening.
