There are currently no plans to support CentOS Stream 9 for Cloud One - Endpoint and Workload Security and this is because CentOS Stream 9 is a collaboration release with the RHEL engineering team.

The main focus of support for version 9 will be on AlmaLinux, RockyLinux, and RedHat Enterprise Linux (RHEL).
