Hi Azeemering and gsales,
It is NOT mandatory to install Splunk Enterprise Security to use ForeScout Adaptive Response add-on. We can still do the response actions without Splunk Enterprise Security.
The error message you see is possibly because communication from CounterACT to Splunk as well as communication from Splunk to CounterACT may not be fully setup or correctly setup. When you have configured all the pieces correctly, you will see that CounterACT will publish the list of actions that can be taken in response to the alerts triggered. This is what you would use to configure the response the alerts. Please refer to the doc here - https://www.forescout.com/products/forescout-app-guide-splunk-2-7-0. This should explain all the necessary steps.
For further assistance, please reach out to email@example.com
Hope this helps.
