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.
A pragmatic playbook for migrating an entire engineering organisation onto zero-CVE base images, covering pilot selection, registry mirroring, drift control, and the hard people-side of the rollout.
An end-to-end view of container supply chain controls from source through registry to runtime, covering signing, attestation, admission policy, and runtime drift, with concrete checkpoints at each stage.
What it actually takes to put Kubernetes admission policy into enforcement mode without breaking deployments: phased rollout, exception workflows, audit-mode hygiene, and policy authoring conventions that survive contact with engineers.
How to validate supply chain attestations at pod admission time without grinding deployments to a halt: which attestation types actually matter, how to chain verifications, and how to fail useful.
A program plan for getting OCI artifact signing across an organisation: trust roots, key custody, build integrations, registry policy, and the inevitable cleanup of unsigned legacy content.
Runtime drift is the last honest witness in container supply chain defence. This post covers what drift signals tell you, how to instrument for them, and how to investigate without overwhelming on-call.
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.
Service meshes are a control plane and a data plane and a supply chain risk surface all at once. This post covers the policy controls that matter in 2026 for sidecars, control planes, and mesh-issued certificates.
Operators are powerful, privileged, and often under-governed. This post covers the supply chain controls that keep operator installations from becoming the largest attack surface in your cluster.
