Background
Digitalising critical infrastructure means connecting things that were never designed to be connected. The networks at the edge, with sensors, meters, controllers and legacy equipment, are heterogeneous, long-lived and often severely constrained in power and processing, which rules out most conventional security mechanisms.
CRITISEC developed security products, services and standards for exactly this layer, addressing legacy systems, constrained devices and the scalability required when a single utility runs tens of thousands of endpoints.
