CRS Interoperability Matrix

This document outlines the supported operating systems and managed Kubernetes environments for the Qualys Container Runtime Sensor (CRS). The CRS relies on eBPF (extended Berkeley Packet Filter) technology, which requires a minimum Linux kernel version of 4.19 or higher for proper operation. 

To ensure full CRS functionality, deploy CRS on environments meeting kernel version ≥ 4.19. CRS has been verified on the listed distributions and managed environments. For other platforms, ensure kernel compliance and contact Qualys support.

For eBPF kernel compatibility details, reach out to Qualys Support.
