Discussion

A Tanium Sensor, also called content, enables an organization to gather real-time inventory, configuration, and compliance data elements from managed computers. Sensors gather specific information from the local device and then write the results to the computer's standard output channel. The Tanium Client captures that output and forwards the results through the platform's unique "ring" architecture for display in the Tanium Console.

The language used for Sensor development is based on the scripting engine available on the largest number of devices under management as well as the scripting experience and background of the people who will be responsible for creating new Sensors. VBScript and PowerShell are examples of common scripting languages used for developing sensors.

Because errors in scripting can and will provide errant feedback at best and will impact functionality of the endpoint to which the content is directed, it is imperative to ensure content is only accepted from trusted sources.
