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 admission controllers intercept every API request before it hits etcd. Here's how validating and mutating webhooks work, what's enabled by default, and where they fail.
Containers and VMs isolate workloads at different layers — kernel vs. hypervisor — which changes attack surface, blast radius, patch speed, and what your scanner actually needs to cover.
Helm chart security means finding and fixing the RBAC, secrets, and supply chain risks baked into Kubernetes' most-used packaging format.
Base image choice sets your CVE floor before any scanner runs. Here's how to evaluate footprint, patch cadence, provenance, and rebuild cycle.
Kata wraps each pod in a lightweight VM. That is a real security boundary. It is also one that comes with real costs and real caveats.
What it takes to standardise on chiseled and distroless container images across an engineering organisation: which workloads benefit, which do not, and how to handle the operational quirks of imageless containers.
Policy design patterns for GCP Binary Authorization that hold up in production: attestor topology, exception handling, continuous validation, and the shapes that stop a deploy-time compromise without blocking legitimate rollouts.
ValidatingAdmissionPolicy GA, VolumeSource for OCI artifacts, and anonymous API cleanup: what 1.30 and 1.31 change for cluster security posture.
Service meshes promise layered policy. The promise is real, but the layers only help if you use them, and most deployments use one.
