SIEM Platforms

SIEM platforms aggregate security events from across infrastructure, applications, and endpoints, correlating them to detect threats and generate compliance reports. They are a central component of security operations for regulated industries. European SIEM providers keep security telemetry within EU borders, with differentiation in detection rule languages, correlation engine performance, and built-in compliance report templates.
