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.
The Kubernetes pod security context controls the privileges your containers run with. Here is how to configure it, and how it relates to the retired PodSecurityPolicy.
The Docker Node version you pin decides your patch cadence, image size, and vulnerability exposure. Here is how to pick and maintain a Node base image safely.
Go and Docker pair well because Go compiles to a static binary that fits in a tiny, near-empty image. This guide shows how to build that image securely.
Picking a Docker security company means judging vendors on the whole container lifecycle — image scanning, runtime, registry, and admission — not just the count of CVEs their scanner prints. Here is a buyer's checklist.
Linux capabilities are the privileges inside a container that attackers reuse after a breakout. Setting Kubernetes securityContext capabilities to drop ALL is the cheapest hardening you will do.
How security context in kubernetes actually works at the pod and container level, what kubernetes runasuser and capability drops do, and a sane default policy to start from.
Real Kubernetes security breaches rarely start with an exotic zero-day — exposed dashboards, misconfigured RBAC, and default credentials show up again and again.
A Java Docker container done right: multi-stage builds, a JRE not a full JDK, non-root users, JVM container-awareness, and a base image that does not ship the world.
A secure Node.js Dockerfile pins a specific base image, runs as a non-root user, and uses multi-stage builds to keep build tooling out of production. Here is a hardened template and why each line matters.
