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 practical guide to hardening container images and deployments. Covers base image selection, build-time security, runtime protections, and Kubernetes-specific controls.
Container security has evolved far past vulnerability scanning. Here is what mature container security programs look like heading into 2025.
Root in the container often means root on the host. Rootless mode breaks that assumption. Here is how to run Docker and Podman without root and why it matters more than you think.
A comprehensive checklist for hardening your container images, from base image selection to runtime protections, with practical Dockerfile examples.
Docker Desktop's WSL2 backend reshaped container security on Windows. Here is what changed in 2022 and the defects that forced those changes.
Podman is daemonless, rootless by default, and fork-exec instead of client-server. Here is what those architectural differences mean for container security in practice.
A review of Tern, the open source tool that generates SBOMs by inspecting container image layers, including its strengths, limitations, and where it fits in your toolchain.
Container images are opaque by default. Here's how to crack them open with SBOMs to see exactly what's running in production.
Every Docker image is a stack of layers, and each one can introduce vulnerabilities. Learn how to dissect image layers for security risks and what tools actually help.
