Isolate Endpoints from Alerts

Workflow #0014

This workflow fetches alerts from Cisco Secure Cloud Analytics (SCA) for the past 24 hours based on the alert name and status provided. Observations are extracted from the alerts and devices are searched for in Cisco Secure Endpoint. If an endpoint is found, host isolation is enabled. Finally, a Webex message is sent with a summary.
