In today’s increasingly interconnected world, operational technology (OT) and building management systems (BMS) play a critical role in the resilience, security, and efficiency of enterprise environments. Yet many organisations still operate with fragmented, outdated, and inconsistent OT deployments, leaving them vulnerable to cyber threats, operational disruptions, and spiralling maintenance costs. This was the reality for a multinational financial enterprise operating across North America, Europe, and Asia. With each region managing its own IT and OT footprints, the business faced significant challenges: overlapping IP ranges, inconsistent vendor practices, limited visibility, weak cybersecurity controls, and no unified governance model. Remote vendor access alone represented a major risk, with little oversight or security enforcement. Recognising the need for a modern, scalable, and secure OT strategy, the organisation partnered with Juberi to reshape its global operations and build a future-ready standard.
The Challenge: Fragmented Systems, Growing Risks
- The company’s OT landscape had evolved in silos over time:
- No global standards or centralised governance
- Outdated systems with minimal security controls
- Inconsistent network designs and vendor hardware
- Limited visibility of assets and performance
- Localised “island” deployments lacking scalability Such an environment made it difficult to respond to emerging cyber threats, ensure compliance, or introduce modern smart-building capabilities.
Our Approach: A Secure, Standardised, Global OT Model
To address these challenges, we delivered a comprehensive, multi-region programme that modernised the client’s infrastructure from the ground up.
- Detailed Global Site Assessments
We began by conducting in-depth assessments across multiple continents to understand the true scope of legacy deployments, integration gaps, and security vulnerabilities. - A Unified Global IP Schema
We designed a repeatable, enterprise-wide IP schema for Building Services Networks, now serving as the foundation for consistent deployments across international sites. - Secure-by-Design OT Architecture
The new architecture incorporated:
• Micro-segmentation Network zoning
• Alignment to ISO 27001 and IEC 62443
• Modern firewalling and secure remote access controls - Major Site Modernisation Projects
Flagship sites, including a major European headquarters, received secure infrastructure upgrades, with legacy systems integrated wherever feasible. - Governance & Vendor Access Oversight
We strengthened access control, improved oversight of third-party connections, and positioned the organisation for SOC integration and enterprise governance through ServiceNow.
The Results: A Safer, Smarter, More Resilient Operation
The transformation delivered measurable improvements across OT security, operational efficiency, and global standardisation. Key outcomes include:
- A fully standardised OT network model now deployed across multiple countries
- Reduced cyber-attack surface through segmentation, modern firewalls, and secure access
- A comprehensive documentation framework simplifying global integration
- Significant improvements in vendor oversight and audit readiness
- Reduced downtime risk through modernised, resilient infrastructure
Business Benefits: Transforming Operations for the Future
Eight primary business benefits were delivered through this programme, each driving measurable value across the organisation:
- Cybersecurity Resilience
Stronger defences against modern threats and fully auditable vendor access aligned to global standards. - Global Consistency
Unified designs that eliminate IP conflicts and streamline troubleshooting and procurement. - Operational Reliability
Improved uptime and stability across mission-critical sites. - Visibility & Control
Clear oversight of OT assets, enabling faster decision-making and proactive risk management. - Cost Efficiency
Lower maintenance overhead and significant savings from standardised technologies. - Strategic Readiness
A scalable foundation supporting future digital initiatives, SOC integration, and evolving regulatory demands. - Cultural Alignment
Improved collaboration between IT and facilities teams under one security framework. - Platform for Energy Innovation
A modern OT ecosystem that can drive data-powered energy efficiency initiatives.
Building the Future of Smart, Secure Operations
Through this global transformation programme, we helped our client move from fragmented, inconsistent OT systems to a unified, secure, and future-ready operational model. The repeatable architecture is now being deployed internationally; reducing risk, saving costs, and giving the organisation the resilience and agility needed for next-generation smart building operations.
If your organisation is facing similar challenges, we’re ready to help you build a stronger, smarter, and more secure future.
