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.
Docker isolation relies on Linux namespaces, cgroups, and capabilities, not a hypervisor. Here is what that really protects and where the boundary is weaker than teams assume.
Most container security policies get written once, ignored during the next sprint, and rediscovered during an audit — here's how to write one that engineers actually follow.
A pod's securityContext decides whether a compromised container is contained or a launchpad. Here are the fields that actually reduce blast radius — and the copy-paste block that sets a hardened baseline.
Docker packages an application and everything it needs into a portable container that runs the same everywhere. Understanding that model is the first step to securing it.
The Docker Ubuntu image is a fine base, but a naive Dockerfile ships a bloated, vulnerable container. Here is how to pin, slim, and scan it properly.
A Kubernetes security tool covers one slice of cluster risk — image scanning, admission control, runtime detection, or posture. Here is how to combine them.
A practical guide to scanning a Snyk Docker image for vulnerabilities: the CLI workflow, base-image advice, free-tier limits, and where container scanning needs a second look.
A Kubernetes security policy is the set of enforced rules that decide what workloads may run and how. This guide covers Pod Security Standards, admission control, and turning intent into rules the cluster actually enforces.
A guide to the Node Ubuntu Docker pattern: when an Ubuntu base makes sense for Node.js, how to build it safely, and the security trade-offs versus slim images.
