SIEM Tool -- Query Translator

SIEM Query Translator

Translate detection queries between Splunk SPL, Microsoft Sentinel KQL, IBM QRadar AQL and Elastic EQL. Handles field filters, time ranges, aggregations and common SOC patterns. Not a compiler -- a practical translation aid for migration and cross-platform work.
