Cert-manager is the universal open-source standard for automating X.509 certificate management in Kubernetes, but by itself it lacks the observability, policy enforcement, and governance required for enterprise security. CyberArk Certificate Manager for Kubernetes extends cert-manager with full visibility across clusters, automated policy controls, certificate audit logging, and removal of self-signed or untrusted certificates. It enforces Infosec policies, validates issuers, and provides developer guardrails while supporting multi-cluster environments. By combining automation with centralized oversight, it reduces outage and breach risks, streamlines developer workflows, and strengthens Kubernetes machine identity security.
