Innovating the SOC – Bridging Cisco XDR and Splunk EnterpriseSecurity at Cisco Live EMEA 2026

The Cisco Live EMEA 2026 SOC team built a bidirectional integration between Cisco XDR and Splunk Enterprise Security to eliminate manual escalation friction between analyst tiers. Tier 1/2 analysts trigger escalations by changing incident status to 'Open: Reported' in XDR, which automatically sends full incident context via API to Splunk's HTTP Event Collector. Two analytics then extract observables and generate native ES alerts with threat topology. Splunk SOAR playbooks promote findings into ES Investigations, copying XDR worklogs and AI summaries. A closing playbook syncs investigation outcomes back to XDR and sends Webex notifications, creating a fully automated, context-preserving bidirectional workflow across platforms.
