NexusVectors helps Saudi organisations prepare for the National Data Index (Nudee) issued by SDAIA, from assessing data management maturity to activating data governance and preparing evidence against NDMO requirements. Senior consultants work alongside the NexusGreenData platform to track readiness and close gaps, while the official score remains SDAIA's alone.
About the index
The National Data Index (Nudee) is issued by the Saudi Data and AI Authority (SDAIA) to measure how mature an organisation's data management and data governance are, and how well it meets NDMO requirements. It gives each entity a single, consistent view of where it stands today and what it needs to improve, with the official score issued by SDAIA alone.
The index has three components: data management maturity, compliance with NDMO controls, and data quality. It spans 15 knowledge domains (14 data management domains plus data security), 77 NDMO controls, 191 specifications and 42 maturity questions, and places each entity on one of five levels from Establishing to Pioneer.
How we help
NexusVectors follows a clear path to Nudee readiness, led by senior consultants and supported by the NexusGreenData platform, taking an organisation from a data management maturity assessment to an improvement plan it can execute and track.
Senior consultants review the organisation's current position across the 15 knowledge domains, benchmark it against NDMO requirements, and identify the main gaps in data governance, data quality and available evidence.
Assessment findings become a roadmap ranked by impact and effort, setting out initiatives, owners and timelines to improve readiness across each component of the index.
NexusVectors helps build the data governance operating model, activate roles and policies, and prepare evidence linked to real data assets through the platform's evidence and compliance management.
The NexusGreenData platform provides an estimated score board and gap-to-action recommendations so the organisation can track its progress continuously, while the official score comes from SDAIA.
What we cover
NexusVectors services and the NexusGreenData platform cover the core areas the National Data Index (Nudee) measures, from data governance and data quality to evidence and compliance, privacy and data classification.
NexusVectors helps assess data management maturity across the 15 knowledge domains and build a data governance operating model with clear roles, policies and procedures. The platform adds a built-in data catalog plus master and reference data management, so governance rests on real assets rather than documents alone.
Data quality is one of the three components of the index. The platform supports defining and measuring quality rules at the data asset level, while consultants help prioritise the dimensions that matter and address root causes, so readiness improves in a measurable way.
The index spans 77 NDMO controls and 191 specifications, each of which needs documented evidence. The platform provides 380 ready evidence templates linked to data assets in the built-in catalog, with document management that tracks the status of every control, and consultants help prepare and review evidence before submission.
Privacy and data classification are covered as part of the index knowledge domains. The platform includes PDPL privacy registers (RoPA, DSAR, breach and DPIA) alongside data classification, linking compliance requirements to the actual data assets they apply to.
The NexusGreenData platform offers an estimated score board for every component and domain, with gap-to-action recommendations that turn findings into tasks with an owner and a date. Teams follow progress in Arabic or English, bearing in mind that these scores are estimates and the official score comes from SDAIA.
Sectors

NexusGreenData's NDI Maturity Index module mirrors NDMO's published structure: 14 data-management domains, their controls and 191 specifications, and 42 maturity questions scored across five cumulative levels — Establishing, Defined, Activated, Managed and Pioneer.
Because it runs on a live data catalog, evidence is linked to real data assets — tables, columns, lineage, glossary terms and policies — instead of a spreadsheet. The result is an estimated maturity and compliance picture your data office can defend internally and act on.
What it does
The 14 in-scope data-management domains, their controls and all 191 specifications, laid out exactly as NDMO publishes them and browsable in Arabic and English.
Each question lists the evidence required at every level, so an entity cannot claim a higher level without the evidence for the levels below it.
Evidence is attached from the data catalog and each item is assigned to an owner. Readiness becomes tracked work with a clear owner, not a static checklist.
Cumulative maturity levels and a compliance estimate are computed from the evidence attached — every number labelled Estimated, with a data-freshness indicator.
Per-level evidence templates speed up collection, and a KPI board tracks indicators over time, including catalog-usage metrics read directly from the platform.
Export the domains, scores, evidence and KPIs as an assessor-ready pack in Arabic and English for internal review and audit preparation.
NexusGreenData reads the data catalog over documented REST APIs and links each NDMO specification to the assets and evidence that prove it, so the assessment stays tied to what is actually in place.
Pick a domain, work through its maturity questions, attach evidence and assign owners. The index updates your estimated level, and the interactive view shows exactly which specifications and evidence stand between you and the next level.

FAQ
Nudee readiness means preparing an organisation to be measured on data management maturity, NDMO compliance and data quality before the official assessment. It covers assessing the current position, closing data governance gaps and preparing the evidence each control requires.
No, the NexusVectors assessment and the NexusGreenData platform scores are estimates intended only to improve readiness. The official National Data Index (Nudee) score is issued solely by SDAIA through its own approved process.
The duration depends on the organisation's size, the number of knowledge domains in scope and how readily documents and evidence are available. It usually begins with a short discovery phase, after which the work plan and estimated timeline for the remaining stages are set.
Typical evidence includes approved data governance policies and procedures, defined roles and responsibilities, the data asset catalog, data quality reports, and privacy and classification registers. The platform provides 380 ready evidence templates linked to real data assets to simplify preparation.
Yes, the service covers privacy and data classification as part of the index knowledge domains and PDPL requirements. The platform includes RoPA, DSAR, breach and DPIA registers alongside data classification, all linked to the data assets they concern.
Yes, the NexusGreenData platform is deployed on-premise within the organisation's own environment, so data and evidence stay fully under its control. The interface is available in Arabic and English to suit different teams.
The National Data Index — المؤشر الوطني للبيانات (نضيء) — is a results-based index published by the Saudi Data and AI Authority (SDAIA). It evaluates how far entities have progressed in data management: the maturity of their practices, their compliance with the national data-management and personal-data-protection standards, and their operational-excellence indicators.
SDAIA owns and publishes the index. Its National Data Management Office (NDMO) issues the National Data Management and Personal Data Protection Standards — the controls, specifications and maturity questions the index measures. Each government entity sets up its own Data Management Office to implement them.
NexusGreenData reproduces the official structure — 14 data-management domains, their controls and 191 specifications — as an interactive index, links every specification to its maturity question and the evidence required at each level, and estimates your achieved level as evidence is attached. Evidence can be assigned to owners, so readiness work is tracked rather than just listed.
No. Every maturity, compliance and operational-excellence number in NexusGreenData is an estimate for internal planning, shown with a data-freshness indicator. SDAIA's NDI platform remains the official system of record; weights and partial-credit rules that SDAIA has not published are configurable and flagged in the interface.
Yes. Master and reference data, data quality, metadata, data classification and personal data protection are all NDI domains. NexusGreenData ships working modules for each, so the gaps a self-assessment reveals can be closed on the same platform, not just reported.
Organisations preparing for Nudee can request an initial readiness assessment that establishes their current position and priority gaps, together with a walkthrough of the NexusGreenData platform.
