View affected systems Topic Red Hat Edge Manager Version 1.1.4 Security Update Description Red Hat Edge Manager (RHEM) provides simple, scalable, and security-focused management of edge devices and applications. It supports image-mode RHEL and container workloads that run on Podman/Docker or Kubernetes. RHEM is now available as a standalone feature, providing greater flexibility for edge deployments. In addition to the standalone version, RHEM continues to be offered as a plugin for the following platforms: Red Hat Advanced Cluster Management (RHACM): Extends fleet management to edge devices. Red Hat Ansible Automation Platform (AAP): Integrates edge management with Ansible automation. This integration enables organizations to optimize the management and orchestration of their fleets of edge devices; whether its thousands of dispersed retail point-of-sale systems or industrial machinery on remote factory floors. Value for customers and partners: This solution not only helps customers manage thousands of devices but helps scale operations. To manage large-scale deployments, customers need to be able to integrate with their existing management systems, support remote configuration and over-the-air updates, and collect telemetry data for advanced analytics. Red Hat Edge Manager offers a simple and security-focused lifecycle management, from onboarding to decommissioning of edge devices. This complete end-to-end solution empowers organizations to gain the most value from the fleets of devices that generate data, all from a centralized location.
