this was developed to address a need for the organization I work for and upon its completion we decided to share with the community. At some point id like to port over to windows solely for the benefit of the community, that being said, being we are not a splunk+windows shop, its not on the top of the list. That being said ,you should be able to use this if you install it on a Linux machine and set it up as a universal forwarder/Heavy and point to your windows indexer.. is your whole environment windows ? including your nessus scanners?
