Narrowin

narrowin is a company focused on network and security engineering for operational technology (OT) and industrial environments. Their team works across the full technical stack, including hardware, network protocols, automation, and software, as well as the organizational processes surrounding these systems. The company positions its work as being conducted directly in industrial settings such as substations, heating plants, factory floors, and plant network cabinets rather than in laboratory conditions. This suggests a hands-on, field-based approach to securing and managing OT and industrial network infrastructure. narrowin also engages with the industrial security community through participation in conferences and trade fairs, including NVIDIA GTC, it-sa Expo&Congress, the Industrial Security Conference (ISC-CPH), the Swiss Network User Group (CHNUG), and SPS - Smart Production Solutions. They have presented on topics such as on-premises AI agents for OT network security, indicating an interest in applying AI technologies to industrial network security use cases. The company also runs its own training courses, such as an OT Network & Security course delivered in partnership with FHNW in Brugg-Windisch, Switzerland, suggesting an educational or knowledge-transfer component to their offering alongside direct engineering work. Based on available information, narrowin appears to operate as a specialized engineering and consulting firm serving industrial and critical infrastructure operators, with a focus on the intersection of networking, automation, and cybersecurity in OT environments.
