# Yandex SIEM

Yandex SIEM is Yandex Cloud's proprietary SIEM system for monitoring and analyzing security events in a cloud infrastructure. Yandex SIEM collects data from the cloud infrastructure to detect anomalies. When Yandex SIEM detects an anomaly, it creates an <a href="../security-deck/concepts/alerts.md">alert</a> indicating a potential incident.
