Marc Strub

Head of OT, IT & ISM (Information Security Management)

Own Renata's OT, IT, and ISM end-to-end — risk posture, access models, and change discipline that hold up in audits and on the night shift; accountability stays with the role, not a vendor deck.

• Ship ADDA on HLL2 — forensic battery-defect analytics from VALTR/MQTT ingest through DuckDB warehouse to a floor investigation UI quality and production rely on under pressure.
• Design and operate the production MQTT/EMQX backbone — broker topology, OT boundary, and access so PLCs/SCADA feed analytics without flattening security or inviting downtime.
• Lead OT/IT integration and industrial IAM decisions that survive real incidents — not paper programs that never touch the plant.
• Apply IEC 62443 thinking to systems that ship — secure IIoT that respects a running factory, not parallel compliance theatre.
