Nano SIEM

Lightweight, open-core SIEM for search, detection, and triage, built on ClickHouse and Postgres.

Webfreemium

Nano SIEM is a lightweight, open-core SIEM for security analysts, offering log search, a piped query language for hunting, and a staged detection-rule lifecycle. The open-source engine installs with one Docker command and stores data in ClickHouse and Postgres; a paid hosted plan adds case management, incident orchestration, an AI assistant, and risk scoring. It's built for security operations teams that want SIEM search and detection without managing a full data lake.
