OT environments often use legacy components and protocols, have access to external providers, and need to be available 24/7. What’s more, the impact of a security incident is potentially significant: financially due to the unavailability of the production environment and environmentally due to the impact on the surroundings, the environment or the health of the employees. The OT assessment maps out the current situation and provides advice on safety measures to be taken in the short and longer terms. To do this, we use frameworks such as ISA/IEC 62443.
