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.
Kubernetes SecurityContext: The Settings That Matter
A pod's securityContext decides whether a compromised container is contained or a launchpad. Here are the fields that actually reduce blast radius — and the copy-paste block that sets a hardened baseline.
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.
Reducing the Attack Surface of Your Docker Images
Every binary, library, and shell in a Docker image is attack surface. Here is how to strip an image down to the bytes your app actually needs — and cut your CVE count by up to 95%.
