Industrial Network Design & Architecture Services
End-to-End OT Network Design for Manufacturing & Energy Facilities
Your network is a critical component of modern industrial operations. When uptime, safety, and data integrity are critical, you need more than equipment; you need a system engineered for reliability and control.
INS designs and implements secure, high-performance operational technology (OT) networks that enable communication between PLCs, SCADA systems, sensors, and enterprise IT systems.
Our industrial network design services help organizations design resilient, maintainable, expandable, and secure networks that prepare for digital transformation, connecting every asset from the control room to the cloud. Whether you’re upgrading a legacy network, segmenting IT and OT systems, or developing an IIoT-ready architecture, INS delivers solutions built to perform.
Part of the INS Network Lifecycle Ecosystem:
Industrial Network Design represents the first step in the INS Network Lifecycle, right before Provisioning & Kitting Services and OT Network Commissioning & Validation. Together, these phases form a complete design-to-deployment process.
Our Front-End Engineering Process: From Concept to Commissioning
A resilient industrial network begins with a design grounded in engineering discipline. INS follows a structured methodology that moves seamlessly from discovery through commissioning.
Deliverables & Outcomes
With INS, you receive more than a design; you gain a detailed blueprint for ongoing performance and growth.
Our design deliverables typically include:
- Network architecture and topology diagrams
- Layered ISA-95 / Purdue segmentation maps
- Bill of Materials and component specifications
- IP addressing schema and configuration templates
- Redundancy and failover plans
- Cybersecurity zone and conduit documentation
- Acceptance testing and validation plans
- Design-to-commissioning milestone roadmap
Each deliverable is engineered to align technical configuration with operational goals, supporting uptime, scalability, and long-term efficiency.

Common Questions
OT network design is the process of designing the communication infrastructure that connects industrial assets, control systems, and IT environments securely and efficiently.
Segmentation isolates control layers, preventing IT or security incidents from affecting plant operations, while improving traffic flow and monitoring.
IIoT depends on secure, structured data flow. Proper design ensures systems can scale to support analytics, edge computing, and predictive maintenance.
