Splunk Add-on for Cisco ESA allows the Splunk software administrator to leverage Textmail, HTTP, Consolidated Event Logs, AMP, Delivery, Bounce, Authentication, Antispam, Content Scanner, Error, and System logs of Cisco ESA. You can use the Splunk platform to analyze these logs directly or use them as a contextual data source to correlate with other communication and authentication data in the Splunk platform.
