CTI-REALM is an open-source Microsoft benchmark that measures AI agents’ ability to operationalize threat intelligence into validated detections by reading CTI reports, exploring telemetry, iterating KQL queries, and producing Sigma/KQL rules across Linux, AKS, and Azure cloud environments; the paper details dataset curation, checkpoint-based scoring, evaluation of multiple model configurations, key findings, and how the community can contribute.
