Why traditional IoT security isn’t enough for smart cities

Public infrastructure runs on real-time data, and attackers know it.
Legacy connectivity models like VPNs or public APNs expose devices to risks once they connect to the internet.
For municipalities and technology providers, that means:

 

  • Public exposure:  once traffic leaves the local network, data travels through unknown nodes.

  • Limited visibility: shared networks make it impossible to see which devices are at risk.

  • Compliance pressure: regulations like NIS2 demand secure, segmented communication.

  • Operational risk: downtime in connected infrastructure affects citizens directly.

 

IXT eliminates those weaknesses with Zero Trust built into the SIM, keeping IoT traffic isolated, private, and verifiable.
