OT Risk Management: Strategies, Lessons Learned, and Challenges

Mathias Pfister
OT Risk Management: Strategies, Lessons Learned, and Challenges

Content of the Presentation

Risk analysis is far more than completing checklists, spreadsheets, and traffic light matrices. When conducted properly, it creates transparency, makes risks understandable, and provides a solid foundation for informed decision-making.

This presentation highlights what truly matters in practice and explains why effective OT risk analysis is much more than a compliance exercise.
