From a command line, running the sc query csagent -version command is not a way to determine the sensor version installed on a specific endpoint. This command will only show the status of the csagent service, not the sensor version. The other options are valid ways to determine the sensor version installed on a specific endpoint using Falcon UI or API. You can use the Sensor Report, the Host Search, or the Host Management features to filter, search, or select the desired endpoint and view the sensor version information12.
