Phoenix Studio
Convert indexed Sigma rules into analyst-ready detections.
This studio is built around Phoenix's own rule corpus, not a blank editor. Search by title or rule id, choose a live sigma-cli backend, then reveal pipelines only when you actually need them.

falsepositives:
- RoleBindings and ClusterRoleBinding being modified or deleted may be performed by a system administrator. Verify whether the user identity, user agent, and/or hostname should be making changes in your environment.
- RoleBindings and ClusterRoleBinding modified or deleted from unfamiliar users should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
