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.
Alpine, distroless, and scratch images don't automatically cut risk. The real attack-surface drivers are capabilities, root filesystem, network policies, and seccomp.
AWS built Firecracker to run Lambda. The security model is the entire value proposition, and it holds up under scrutiny.
A practical walkthrough for signing container images with Cosign using keyless OIDC, verifying signatures, and enforcing policy in your Kubernetes cluster.
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.
containerd runs most of Kubernetes today. Its defaults are reasonable, but reasonable is not hardened. Here is how to close the gaps.
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.
BuildKit's caching is what makes container builds fast. It is also a potential vector for cache poisoning attacks if not properly secured.
What is CIEM? A clear breakdown of Cloud Infrastructure Entitlement Management, how it differs from CSPM, and why excessive cloud permissions keep piling up.
