Tenzir is a German company that builds a security data pipeline platform for security operations teams. Its programmable pipelines collect, shape, enrich, route and store security telemetry, for example to send logs to a SIEM or to lower-cost storage. The base engine is available as open-source software and can run from the command line or on the organisation's own infrastructure. Commercial editions add a web interface, hosted delivery (SaaS) and enterprise features.
The company is based in Germany, an EU member state. The vendor's public material does not say where hosted editions store customer data. Because the open-source engine can run on your own infrastructure, European users can keep telemetry within their own environment. For a European organisation, the key question is therefore where the hosted editions run and who operates them. That can be settled in the contract before telemetry is sent to a SaaS environment.
