Splunk

Splunk is an industry-leading SIEM and observability platform that ingests machine data from across an organization's infrastructure to deliver real-time security monitoring, threat detection, and compliance reporting. Its powerful SPL (Search Processing Language) enables security analysts to query petabytes of logs and events to investigate incidents and build automated detection rules.

With both on-premise and cloud deployment options, Splunk fits enterprise environments with strict data residency and sovereignty requirements.
