This app's functionality has been added to the Splunk App for SOAR (https://splunkbase.splunk.com/app/6361/). We recommend you use that app for this functionality and future updates. The Phantom Remote Search add-on defines indices and roles used by Phantom when configured to use an external Splunk instance for search data. Install this app if you plan to use this Splunk instance as a remote search node for Phantom.
