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.
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.
A practical guide to rolling out Tetragon for kernel-level runtime visibility, covering policy authoring, performance overhead, and integration with existing detection pipelines.
What is Cosign? A precise look at how this Sigstore tool signs and verifies container images, keyless signing, and how it compares to Notary v2.
Alpine, distroless, and scratch images don't automatically cut risk. The real attack-surface drivers are capabilities, root filesystem, network policies, and seccomp.
Helm charts are the most common Kubernetes deployment artifact and the least scrutinised. This blueprint covers chart provenance, signing, value validation, and the runtime correspondence checks that close the loop.
Why multi-architecture container images break assumptions baked into signing, SBOM, and attestation tooling, and how to build a multi-arch pipeline that stays verifiable.
A container escape lets attackers break out of a container into the host or other workloads. Learn how these attacks work, real CVEs, and Kubernetes risk.
