OT Cybersecurity for Smart Cities

Remotely managed drinking water networks, smart lighting, traffic management, connected urban sensors: the smart city multiplies the points of convergence between legacy physical infrastructure and new digital systems, often managed by public utilities with limited resources. Seclab, for example, supported Sourcéo, the public water utility of the Lille European Metropolitan Area, in securing the industrial networks serving 1.1 million residents. 

Sector-specific challenges 

  • Multiple connected systems: water, energy, mobility, lighting, video surveillance, each of these systems has its own protocols and maturity levels. 
  • Direct impact on the population in the event of an incident: water outages, contamination, traffic gridlock, public lighting failures. 
  • Often limited human and budgetary resources at public utilities and local authorities, which must nonetheless meet the same regulatory requirements as large corporations. 
  • Legacy infrastructure managed remotely, with multiple maintenance access points that are sometimes poorly controlled. 

How Seclab protects your urban infrastructure 

Seclab offers a progressive approach, designed for organizations that don’t always have a dedicated cyber team: a step-by-step increase in maturity, without disrupting services essential to the population. Xplore maps all connected assets across an urban network (valves, sensors, remote management stations), provides views that are easy for field teams to understand, and continuously detects anomalies or attacks; Xchange isolates the most critical systems, such as drinking water production and distribution; and Xport secures on-site USB maintenance operations, often carried out by external contractors. 

Use case 

Sourcéo, public water utility of the Lille European Metropolitan Area (1.1 million residents, 4,000 km of network).
