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.
Kubernetes securityContext capabilities let you strip Linux kernel privileges from a container instead of accepting the runtime default set — here's when to drop, when to add back, and why dropping ALL first is the right starting point.
A well-written docker ignore file keeps secrets, git history, and local cruft out of your images — one of the cheapest and most overlooked container security wins.
The real Kubernetes security risks are misconfiguration, over-permissive RBAC, exposed control planes, and vulnerable images, not exotic zero-days. Here's how to prioritize.
Docker Compose privileged mode hands a container nearly all host capabilities. Here is what --privileged actually turns on, and the scoped alternatives that do the same job safely.
docker run privileged and docker compose privileged both hand a container root-equivalent access to the host — here's exactly what that means and when, if ever, it's justified.
A field-by-field walkthrough of Kubernetes securityContext — fsGroup, runAsNonRoot, and the settings teams leave at their insecure defaults.
You can build a solid container security stack entirely from open source tools — here's which ones cover which layer, and where the gaps show up at scale.
A working checklist for building secure Docker images, from base image choice through image scanning, that you can actually apply to an existing Dockerfile this week.
Container vulnerability management is a lifecycle, not a scan — here's what happens from base image selection through runtime, and where most programs quietly fall apart.
