For global energy organizations, Operational Technology (OT) is inseparable from safety, reliability, and continuity of operations. As OT environments expand across sites, systems, and vendors, visibility alone is not enough. Without strong governance and access control, visibility can quickly become risk.
A global energy organization launched an initiative to modernize how OT data is governed and secured on the ServiceNow platform. The goal was to define a Minimum Viable Product (MVP) that could safely support OT visibility, data ingestion, and access control while laying the groundwork for long-term scale.
To accelerate progress and reduce risk, the organization engaged CoreX for an OT MVP advisory engagement focused on security architecture, data strategy, and execution readiness.
Challenge
The organization faced several structural challenges early in its OT modernization effort. These challenges created a real risk: moving quickly could expose sensitive OT data, while moving cautiously without clarity could stall momentum.
- OT access controls relied heavily on scripted ACLs, creating security gaps where GlideRecord queries could bypass protections
- Subproduction environments carried elevated administrative access, increasing the risk of unauthorized OT data exposure
- OT data ingestion through Service Graph Connector (SGC) and IntegrationHub ETL was early-stage and lacked consistent transformation logic
- MVP scope and success criteria were not clearly defined, creating uncertainty around what “ready” looked like
- The CMDB approach required careful alignment to support OT-specific data models without introducing performance or governance issues
Solution
CoreX partnered with the organization to deliver a focused OT MVP advisory engagement designed to reduce ambiguity and harden the foundation before build activities began. The work centered on four pillars:
OT-Specific RBAC Architecture
A comprehensive review of all OT-related tables and access paths was conducted to define a multilayered RBAC model that enforces security across UI, reporting, workflow, and scripting contexts. The recommended approach reduced reliance on scripted ACLs and established scalable access patterns aligned to OT governance requirements.
Security Risk Identification and Mitigation
The engagement identified specific ACL bypass risks and subproduction exposure scenarios. CoreX delivered short-, medium-, and long-term recommendations to immediately reduce risk while positioning the organization for mature OT governance.
SGC and OT Data Ingestion Guidance
CoreX evaluated the organization’s Service Graph Connector and IntegrationHub ETL approach, providing guidance on data modeling, transformation logic, and OT asset representation to ensure completeness and long-term usability of ingested data.
Clear MVP Definition and Validation Strategy
The engagement produced a clearly defined OT MVP scope, success criteria, and validation approach to support a confident transition into build and UAT phases.
Rather than resetting the program, the advisory work strengthened and clarified the existing design while preserving momentum.
Results
The advisory engagement delivered immediate clarity and risk reduction:
- A clearly defined OT MVP scope aligned to security, governance, and visibility objectives
- A hardened RBAC architecture that reduced OT data exposure risk
- Validated guidance for OT data ingestion and CMDB alignment
- Reduced ambiguity for implementation teams entering build and UAT
- Stronger alignment between IT, OT, and security stakeholders
With foundational risks addressed and expectations aligned, the organization was positioned to proceed confidently into OT MVP implementation with a secure, scalable architecture.
Summary
By investing in advisory work upfront, this global energy organization avoided common pitfalls that derail OT modernization efforts. Instead of rushing visibility at the expense of security, it established a governed, production-ready OT foundation designed for scale.
As the organization moves forward with OT MVP build and expansion, it does so with confidence that the foundation is secure, intentional, and built to last.
