The threat landscape for cloud-native environments like Kubernetes is always on the move. Attackers continuously apply sophisticated techniques. Cryptojacking, the unauthorized use of computing resources to mine cryptocurrency, is a particularly concerning threat. Cryptojacking can lead to performance degradation, increased operational costs, and potential security breaches. Recent high-profile incidents underscore the importance of addressing these threats.

We’re excited to announce Kubesleep, a smart Kubernetes operator developed by SUSE that optimizes cluster efficiency and significantly reduces infrastructure costs. Kubesleep automatically scales workloads based on actual developer activity, intelligently detecting periods of inactivity and scaling down resources to save energy and expenses. Best of all, your clusters smoothly scale back up before developers even notice.

In March 2025, Wiz researchers disclosed a set of critical vulnerabilities in the popular ingress-nginx controller for Kubernetes. Collectively referred to as IngressNightmare, these issues (CVE-2025-1097, CVE-2025-1098, CVE-2025-24513, CVE-2025-24514, and CVE-2025-1974) allow unauthenticated attackers to exploit the Ingress admission controller, potentially achieving remote code execution or escalating privileges in the cluster.

If you’re new to Kubernetes or looking to modernize your cluster management workflows, Cluster API and SUSE Rancher Prime make it easier than ever to provision and manage clusters declaratively. This guide walks you through enabling Cluster API in SUSE Rancher Prime, deploying your first cluster and exploring advanced features like GitOps. Some helpful documentation can be found here and a few pre-requisites for this hands-on walkthrough.

Blog written by: Ivan Sim SUSE Virtualization – Enforcing Admission Resource Integrity With Validating Admission Policy With more enterprises using SUSE Virtualization (formerly Harvester) as the bedrock virtualization platform to host their modern cloud-native AI and edge workloads, it’s important that the platform provides seamless built-in guardrails to validate and sanitize resources admitted into the environment.

Managing multiple teams in Kubernetes can feel like juggling too many balls at once. Have you ever struggled with resource conflicts, security risks‌ or simply keeping everything running smoothly when everyone shares the same cluster? If so, you’re not alone. Let’s dive into how virtual clusters can transform this chaos into a well-orchestrated symphony.

Kubernetes has revolutionized how we deploy and manage applications, but juggling clusters across clouds and on-premises environments can quickly become a tangled mess. Different tools, inconsistent configurations‌ and manual processes drain your team’s time and energy. What if there was a way to simplify Kubernetes cluster management, bringing order to the chaos? Enter Cluster API (CAPI) and SUSE Rancher Prime.

At SUSE, we’re always looking for ways to make it easier for customers to maintain secure, enterprise-grade environments. The Rancher Security team is excited to announce the public beta launch of the Rancher CVE Portal, available now at scans.rancher.com. This new resource is a significant step forward in providing clear, actionable visibility into vulnerabilities affecting Rancher and its associated dependencies.
