- This is an IoT gateway deployment across Oil & Gas OT levels — smaller gateways fitting field cabinets near sensors and controls
- while higher-level gateways handle larger data volumes
- dashboards
- cloud or enterprise connectivity
- giving the site a tiered architecture rather than one gateway type trying to do every job
Case Studies
Layered Oil & Gas IoT Gateway Architecture
26 Jun 2026DIN-rail IoT and cybersecurity gateways for field aggregation, real-time management, and OT/IT protection.
Overview
ChallengesThe main challenges were
- Oil and gas sites need compact field gateways
- protocol conversion
- data filtering
- reliable operation in hazardous field cabinets
- remote management
- wireless connectivity options
- cybersecurity protecting the boundary between OT and IT
ObjectivesThe system needed to
- Aggregate sensor and control data
- optimize processes
- provide real-time management
- support remote monitoring and dashboards
- protect the OT/IT boundary from abnormal packets or cyberattacks
Solution DeliveredThe solution included
- Compact gateways were used at the field level for sensor and control-data aggregation and command forwarding, sized to fit inside space-constrained hazardous-area cabinets near the equipment itself
- Higher-performance gateways handled the larger data volumes and dashboard functions further up the architecture, where more processing headroom and connectivity options matter more than compact footprint
- A DIN-rail cybersecurity gateway sat specifically between the OT and IT layers, providing firewall/VPN protection and packet filtering at that boundary — the point in the architecture where a compromise on the IT side could otherwise reach directly into field control systems

Conclusion
IoT gateway deployment covering, Field data acquisition, operational management, and cybersecurity at the OT/IT boundary. A strong Oil & Gas application story!
