 Automatic Import helps you quickly parse, ingest, and create https://www.elastic.co/elasticsearch/common-schema[ECS mappings] for data from sources that don't yet have prebuilt Elastic integrations. This can accelerate your migration to {elastic-sec}, and help you quickly add new data sources to an existing SIEM solution in {elastic-sec}. Automatic Import uses a large language model (LLM) with specialized instructions to quickly analyze your source data and create a custom integration. 
 
 While Elastic has 400+ {integrations-docs}[prebuilt data integrations], Automatic Import helps you extend data coverage to other security-relevant technologies and applications. Elastic integrations (including those created by Automatic Import) normalize data to {ecs-ref}/ecs-reference.html[the Elastic Common Schema (ECS)], which creates uniformity across dashboards, search, alerts, machine learning, and more.
