QueryPie KAC (Kubernetes Access Controller) by CHEQUER is a Kubernetes API protection solution designed for managing cloud infrastructures such as AWS EKS or on-premise Kubernetes clusters. It enables administrators to manage Kubernetes access, monitor API requests, and replay container command executions. QueryPie KAC integrates into existing Kubernetes environments, allowing administrators to manage user lifecycles with identity providers. Users can request Kubernetes resources via API using third-party clients, with 'kubectl' commands passing through QueryPie's proxy for access control and audit. The solution is designed to protect Kubernetes both within and outside of namespaces.
