!The Challenge
Development teams were deploying containerized applications to Kubernetes without standardized security controls. CI/CD pipelines lacked security scanning, container images were not validated, and there was no runtime security monitoring in the cluster.
→The Solution
Implemented pod security policies, network policies, and RBAC across all Kubernetes namespaces. Integrated container image scanning (Trivy, ECR scanning) into CI/CD pipelines. Deployed runtime security monitoring with Falco. Established GitOps workflows with security gates and implemented secrets management with AWS Secrets Manager.
✓Key Results
Container vulnerabilities reduced by 75% through automated image scanning
40-55% cost reduction through optimized container resource allocation and spot instances
CI/CD pipeline security gates blocking 100% of critical vulnerabilities from production
Runtime threat detection with <5 minute alert time via Falco
Secrets management centralized — eliminated hardcoded credentials across 50+ repos
Security-as-Code adopted by all development teams
