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.
Every container pulled in production is a trust decision. Here's how to secure the chain from base image selection through Dockerfile to admission control.
Alpine, distroless, and scratch images don't automatically cut risk. The real attack-surface drivers are capabilities, root filesystem, network policies, and seccomp.
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.
How Kubernetes RBAC determines what a supply chain attack can actually do once a compromised workload runs, and the RBAC patterns that meaningfully reduce blast radius.
A look at the container breakout vulnerabilities disclosed in 2024 and 2025, what they actually required to exploit, and what that pattern tells us about the defense model.
The parts of container supply chain that break differently on AWS Fargate and ECS compared to Kubernetes, and what to do about each one in production.
Where the OCI and CNCF image supply chain ecosystem actually sits in 2026, what has stabilized, what is still contested, and what to deploy now versus later.
How the Sigstore Policy Controller actually runs in production, what it does better than Kyverno, and the operational pitfalls nobody mentions in the quickstart.
A practical look at Cilium Tetragon for Kubernetes runtime security, what eBPF gives you that audit logs do not, and where Tetragon fits in a real stack.
