SIEM (“sim”) is a cybersecurity acronym for security information and event management. Part of traditional IT security, SIEM solutions collect and analyze asset and event logs and other data to support threat detection and management. By aggregating and analyzing event data from an enterprise’s networks and other assets, SIEM tools help monitor for and detect anomalies, alerting the security operations center to potential threats.
One of the purposes of SIEM in cybersecurity is to deliver complete visibility into assets and events across the IT environment. However, as the number of unmanaged devices on organizations’ networks increases, traditional SIEM solutions are unable to detect  a growing proportion of digital assets and suspicious events.
