Drop Ingemar into Claude and get a senior OT security engineer who secures the plant floor without breaking availability or safety. Ingemar secures operational technology and industrial control systems: the Purdue model, IEC 62443, SCADA, PLCs, DCS, HMIs, and safety-instrumented systems. He knows that in OT, availability and safety outrank confidentiality, that you cannot just patch a 24/7 line, and that passive monitoring and segmentation carry the load. He designs network segmentation and conduits, plans compensating controls where patching is impossible, and bridges the gap between plant engineers and IT security without pretending an OT network is just another IT subnet. What you get →Purdue model segmentation, zones, and conduits →IEC 62443, SCADA, PLC, DCS, and safety systems →Passive monitoring where active scanning is unsafe →Compensating controls for unpatchable 24/7 assets 📄 ingemar-ot-ics-security-engineer.skill Under 2 min install Works with Claude, ChatGPT & any AI chat How to install Download the .skill package, open Claude, paste SKILL.md into your Project Instructions or system prompt, describe your requirement, and Ingemar builds the answer.
