What is CIS Data Foundations (CMDB and CSDM)?
CIS Data Foundations is a ServiceNow certification that demonstrates the ability to model, govern, maintain, and extract insights from data. CMDB Aligned with CSDM, it serves as a fundamental link for other implementations and certifications on the platform, standardizing the understanding of data before advanced modules.
Why did ServiceNow create CIS Data Foundations?
ServiceNow has made CIS Data Foundations a mandatory prerequisite for several CIS certifications—including ITSM, Discovery, HAM, SAM, Service Mapping, SIR, and VR. The goal is to ensure that professionals who implement or maintain advanced modules share a common foundation on CMDB and CSDM, reducing modeling issues, inconsistent data, and poor governance.
For those who already hold active certifications, the deadline to obtain the CIS Data Foundations certification is December 31, 2026; without it, current credentials may expire. In practice, the certification has become the new "ground zero" of the ServiceNow ecosystem.
What does CIS Data Foundations cover?
The certification assesses a broad set of CMDB management competencies and CSDM adoption:
| Domain | What is being evaluated? |
|---|---|
| CMDB Fundamentals | CI classes, hierarchy, attributes, lifecycle, identification and reconciliation. |
| CSDM Fundamentals | Domains and layers of CSDM (technical, business, and portfolio services) and mapping of CIs through best practices. |
| Ingestion and reconciliation | Data import, IRE, identification rules, and integration via Service Graph. |
| Governance and health of CMDB | Quality controls, health dashboards, compliance, data certification, and duplicate prevention. |
| Insight and report | Reports, dependency maps, Query Builder, and data visibility for IT decisions. |
The exam also requires mastery of best practices in implementation, ongoing maintenance of the CMDB, and data-driven design—critical factors for ensuring reliable data over time.
What is the Data Foundations (CMDB and CSDM) Certification Suite?
The Data Foundations Suite Certification consolidates a set of data-centric credentials as the foundation of the platform. To obtain it, you need to:
- to pass the CIS Data Foundations exam (CMDB and CSDM);
- Complete the non-proctored micro-certifications "CMDB Health" and "Configure the CMDB".
Thus, the professional demonstrates not only theoretical knowledge, but also practical mastery of governance, health, and CMDB configuration — a value recognized by clients and employers.
Practical impacts of the change
The mandatory requirement has generated mixed reactions. For those who work with CMDB/CSDM, it makes sense: it consolidates standards, improves data quality, and avoids rework. For consultants with older certifications and little recent experience in CMDB, it represents additional study and costs.
Advantages
- Standardization of knowledge among professionals who implement critical modules;
- Greater data quality, consistency, and governance, with more robust implementations;
- Recognition of competence in CMDB/CSDM by the market and clients.
Challenges
- The need to revalidate old certifications by 2026 requires time and study;
- Extensive content for those who do not routinely deal with CMDB;
- There is an urgent need, for companies and partners, to plan the updating of their teams.
CIS Data Foundations is free of charge.
