One year ago, our team was shipping 120 Docker containers weekly with zero runtime security checks, leaving 68% of production images vulnerable to high-severity CVEs. Today, we’ve reduced that rate to 1.2%, cut secret leak incidents to zero, and slashed compliance audit prep time from 14 days to 4 hours—all using Docker 28, Trivy 0.55, and HashiCorp Vault 1.18. This is the unvarnished retrospective of building zero-trust container security that actually works, not the vendor pitch you’ve been sold.
