Elastic

Elastic provides the Elastic Stack (formerly ELK Stack) — Elasticsearch, Logstash, Kibana, and Beats — the most popular open-source platform for search, logging, and observability. Elasticsearch is a distributed search and analytics engine used by thousands of organizations for log analysis, full-text search, and security analytics. The Elastic Observability solution combines logs, metrics, and APM data in a unified platform, leveraging Elasticsearch's powerful search and analytics capabilities. Elastic Security provides SIEM, endpoint detection and response, and cloud security capabilities built on the same platform. Elastic Cloud provides managed Elasticsearch deployments on AWS, Azure, and Google Cloud, while the self-managed option remains available for organizations that prefer to run their own infrastructure. The platform's machine learning capabilities provide automated anomaly detection across all data types.
