Does this TA Support Nessus Home installations?
I've tried to use Tenable.io and authentication seems to work but no data is received.
Is Tenable Home a cloud SaaS? If not, this is the TA that does ingestion from "on-prem" style logs: https://splunkbase.splunk.com/app/1710/
Also, I don't have any experience with this one but here it is, might try it out: https://splunkbase.splunk.com/app/2740/
have you verified that the input stanza does actually ingest any files?
