A list of companies relying on Elasticsearch reveals a wide range of use cases — from documentation search at Read the Docs to SIEM and XDR logging at LawVu. GitHub hosts cloud infrastructure on it, while Ivanti leverages it for data hosting tied to its Neurons MDM platform. The diversity of implementations across 133 total results shows how deeply the search engine has embedded itself in developer tooling and enterprise security stacks.

Among the listings, companies like Check Point Software use Elasticsearch for search functionality, Keap applies it to search and analytics, and Resend runs in-app search on a lean 50-person team. Writer relies on it for infrastructure, and Torq taps it for search functionality in incident response. Help Scout uses it for data processing enhancement. Each deployment reflects different engineering priorities — some prioritize user-facing search, others lean on it for backend analytics and logging.

What stands out is the variety of company sizes deploying Elasticsearch, from 50-person startups like Resend to 1000+ employee firms like GitHub and Ivanti. The data confirms Elasticsearch has moved well beyond log aggregation into search, analytics, and infrastructure support across documentation platforms, security tools, and developer services.
