CyberArk Workload Identity Manager secures Istio service meshes by replacing insecure self-signed certificates with enterprise-approved PKI, ensuring all workload identities are trusted and compliant. It issues unique SPIFFE IDs to workloads, enabling strong mutual TLS authentication and consistent policy enforcement across multi-cluster and multi-cloud environments, including VMs. The solution provides observability, automates short-lived identity issuance, and simplifies secrets management, supporting zero trust and post-quantum readiness. By integrating with cert-manager, it streamlines workload authentication, reduces outages, prevents impersonation attacks, and consolidates mesh identity governance under a single, scalable platform.
