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.
Scanning tells you what could go wrong before deploy. Runtime monitoring tells you what is going wrong right now. Here is how to detect container attacks as they happen.
Layer caching makes builds fast — and quietly bakes secrets into layers, hides unpatched base images, and poisons shared CI caches. Here is how to keep caching without the exposure.
eBPF lets you observe and enforce security at the kernel level — every syscall, network connection, and process exec — without kernel modules or instrumenting your apps. Here is how tools like Falco, Tetragon, and Cilium use it to catch what image scanning cannot.
A service mesh can give you mutual TLS between every service, identity-based authorization, and encrypted traffic without touching application code — or it can become an over-privileged proxy layer you never locked down. Here is how to do it right.
A fail-the-build scanning pipeline is a few YAML lines away — but pin the Action wrong and you inherit its supply chain risk too.
Docker retires Content Trust on December 8, 2026, while fewer than 0.05% of Hub pulls ever used it — here's how Sigstore and Notary v2 actually replaced it.
A CVSS 9.0 flaw in NVIDIA's Container Toolkit let any GPU container escape to the host — and its first patch didn't fully close it. Here's how to defend AI infrastructure.
A container-local root shell is not the flag. CVE-2019-5736 and CVE-2021-4034 both show how a SETUID binary inside a container can become a host compromise.
Multi-stage builds can cut a Node.js image from 1GB+ down to under 150MB — but most teams still ship dev dependencies, root shells, and unscanned base layers to production.
