About

The ServiceNow Certified Implementation Specialist - Discovery (CIS-Discovery) is a professional-level credential for IT Operations Management specialists who design and implement automated discovery of IT infrastructure assets. Launched circa 2014 and updated three times yearly to align with ServiceNow release cycles, it validates expertise in MID Server configuration, discovery pattern design, probe and sensor behavior, CMDB reconciliation logic, credential management, IP-based and cloud discovery techniques, service mapping integration, and troubleshooting of discovery pipelines. Prerequisite: CSA (foundational) plus hands-on Discovery Implementation course. Suitable for ServiceNow ITOM engineers, CMDB specialists, infrastructure automation consultants, and solution architects leading discovery initiatives in mid-to-large IT environments.

Domain context — IT Operations Management (ITOM)

Automated discovery, mapping, and management of IT infrastructure across physical, cloud, and hybrid environments. ServiceNow Discovery module: MID Server agents, discovery patterns, CI/service mapping, CMDB data population, reconciliation workflows, IP-based scanning, cloud connector discovery (AWS/Azure/GCP), credential and schedule management, performance tuning.
