Red Hat OpenShift And Zero Trust: Securing Workloads With Cert-manager And OpenShift Service Mesh
Red Hat News, Friday, April 4th, 2025
Version 1.15.1 might feel like a run-of-the-mill new release of cert-manager Operator for Red Hat OpenShift but actually it features more than a few notable enhancements to improve the security posture of your OpenShift clusters.
This exciting release improves the overall security posture of your OpenShift clusters, and expands upon your ability to protect your cluster networking communications with TLS certificates managed by cert-manager. The release of Red Hat OpenShift 4.18 emphasises zero trust architecture, and introduces as Technology Preview, the powerful istio-csr agent via cert-manager's new release.
The istio-csr agent enables a seamless integration with the Istio service mesh, allowing cert-manager to secure Istio workload and control plane components. The istio-csr agent is responsible for receiving all certificate signing requests from members of the Istio mesh and signing them with cert-manager.
