Netwrix support exporting events using either CEF or event-log formats - both of which Loom can easily ingest.
To connect Netwrix and Loom, please install one of the two (free) plugins found here.
Then, create a scheduled task that creates an export file periodically (the instructions can be found in the corresponding quick-start guides, e.g. here).
Once the file is created, follow the instructions in Loom data-input screens to have the data streamed in real-time to Loom.
