Reducing Docker image build time without sacrificing security
Multi-stage builds and minimal base images can cut CI build times dramatically — and they're the same changes that shrink your CVE attack surface.
Why You Need a Kubernetes Admission Controller
RBAC decides who can call the Kubernetes API — it has no concept of what a pod spec contains, which is why privileged containers still slip through into clusters every day.
Docker Secrets Management: Stop Baking Credentials Into Images
A secret written into a Docker layer is recoverable forever, even after you delete it. Learn the build-time and runtime patterns that keep credentials out of your images entirely.
Securing Managed Kubernetes: EKS, AKS, and GKE Compared
A cross-cloud guide to hardening managed Kubernetes — the shared responsibility line, cloud IAM-to-pod integration, network policy, Pod Security Standards, and node hardening across EKS, AKS, and GKE.
Minimal Base Images for Security: A Practical Guide
Minimal base images cut CVE counts by up to 95% by shipping only what your app needs. Here is how to choose between distroless, Wolfi, Alpine, and scratch — and build on each safely.
Trivy vs Grype: A Neutral Open-Source Scanner Comparison for 2026
Trivy and Grype are both free, open-source vulnerability scanners loved by engineers, but they differ in scope and philosophy. An honest side-by-side, plus where a managed third option fits.
Alpine vs Debian Base Image Security: Which Is Safer?
Alpine is tiny and dodged the xz backdoor; Debian has deeper security tracking and broader compatibility. Here is how the two base images actually compare on security — and how to harden either one.
Cloud Workload Protection: A Practical Guide to CWPP in 2026
What cloud workload protection (CWPP) actually covers across VMs, containers, and serverless — how it differs from CSPM and CNAPP, what to configure, and where build-time scanning fits.
Distroless vs Alpine: Which Base Image Is More Secure?
Alpine is tiny and familiar; distroless is tinier and shell-free. The right choice depends on what you value more — debuggability or a minimal attack surface. Here is the honest tradeoff.
Scanning Docker Images in CI/CD Pipelines
Scanning a container after it deploys is an incident report. Scanning it in the pipeline is a one-line diff. Here is how to gate builds on image scans without drowning developers in false positives.
Container Image Scanning Best Practices
A practical guide to container image scanning: when to scan, what to block, what scanners like Snyk miss, and how to build a policy that actually gets remediated.
Container Security for Beginners: Keeping Your Docker Images Safe
Containers made shipping software wonderfully simple, but they also package up whatever risks come along for the ride. Here is a beginner-friendly introduction with a first image scan you can run today.
