Full name:
Elasticsearch HTTP API
What is port 9200?
Port 9200 is the HTTP REST API endpoint for Elasticsearch, one of the most popular search engines and analytics platforms. It is a core component of the ELK Stack (Elasticsearch, Logstash, Kibana) used for log analysis. Older versions had no authentication by default — thousands of exposed instances led to massive data breaches affecting billions of records. Always enable X-Pack security (or OpenSearch Security) and place Elasticsearch behind a firewall.
