About
Siren is an investigative intelligence platform used by government and enterprise organizations to safeguard people, assets, and networks.

The platform spans national security, public safety, fraud and compliance, and cyber threat use cases. Siren Investigate delivers an enterprise search engine combined with dashboards and link analysis visualizations. Siren Federate connects distributed data sources without centralizing them. Founded in 2014 as a spin-off from the Data Intensive Infrastructure research group at the National University of Ireland Galway, Siren has received investment from the European Investment Bank and strategic backing from Elastic.
