Cybersecurity for a Global Construction Leader
Interval delivered specialised cybersecurity, cloud and OT expertise to help a major construction group close critical security gaps and build long-term resilience across its global IT and OT environments. The programme focused on strengthening network security, introducing modern cloud architectures and improving remote access controls to protect high-value operations.
Background
A global construction enterprise identified urgent vulnerabilities across its IT, cloud and operational technology (OT) landscape. Legacy systems, inconsistent access controls and fragmented network security had created operational risks that required immediate remediation.The client needed niche expertise across cloud architecture, network security and OT platforms to address short-term gaps and establish a future-ready cybersecurity foundation.
The Challenge
The client required a coordinated cybersecurity uplift across multiple domains:
Limited internal capacity to strengthen cloud, IT and OT security in parallel
Lack of specialist expertise in edge computing, network security frameworks and industrial architectures
Legacy OT environments requiring modern segmentation, monitoring and access controls
Manual and inconsistent remote access revocation processes on F5 platforms
The need for a unified approach that could support global operations and future cloud adoption
Our Solution
Interval assembled a blended team of cloud, network and OT security specialists to deliver a structured and scalable programme.
Cloud Architecture
Developed a full edge computing concept
Defined a cloud-aligned reference architecture and support model
Identified technical requirements for edge services and optimised data storage and protection for critical workloads
Network and Security
Designed and implemented updated network and security standards
Delivered a Proof of Concept for enhanced network protection
Defined an OT LAN segmentation model to strengthen isolation from cyber threats
Established equipment standards and vendor recommendations for the OT LAN architecture and industrial DMZ (iDMZ)
OT Remote Access
Assessed and automated the access revocation process on F5 platforms
Designed automation scripts and a roadmap for implementation
Upgraded the VPN approval flow to tighten security and streamline remote access
Results
New edge computing concept enabled secure cloud integration and improved management of critical application data
Network and security enhancements resolved key vulnerabilities and improved resilience across production and office environments
OT LAN segmentation and iDMZ architecture delivered stronger protection for industrial systems
Automated remote access controls reduced risk by preventing unauthorised connections and improving operational efficiency
The client achieved a more robust, cloud-enabled and secure global IT and OT environment, better prepared to withstand emerging cyber threats
Client Testimonial
“Interval quickly understood the complexity of our IT and OT landscape and delivered experts who could make an immediate impact. Their ability to strengthen our network security, define a modern cloud architecture and streamline OT access controls has significantly reduced our risk exposure. The quality of delivery and the clarity of communication made a real difference to the success of this programme.” - Vice President IT
Conclusion
By providing targeted cloud, network and OT expertise, Interval helped the client strengthen its cybersecurity posture and establish a scalable foundation for future digital transformation. The programme not only mitigated immediate risks but also equipped the organisation with the architecture, processes and controls needed to protect operations worldwide.
