Description
While the Tanium Server records audit log entries to the Tanium SQL database, retrieval and aggregation of log data through the Tanium console is not efficient. The Tanium Connect module allows for SIEM connectors in order to facilitate forensic data retrieval and aggregation efficiently. Consult documentation at https://docs.tanium.com/connect/connect/index.html for supported Connections.
