Are your city’s vital systems protected from cyber threats?

Municipalities allocate much of their resources to developing smart cities, efficient services and connected infrastructure. Bridges, traffic lights, waste bins and air meters have become a part of this digital network. But is enough attention being paid to its vulnerabilities? The digital progress comes with cybersecurity risks, which must be considered, as single attack can paralyse critical public services and undermine citizen trust.

more ransomware attacks hit government agencies in early 2025 compared to the year before.

Keep your OT safe from digital risks Why OT and IoT systems need protection in every municipality

Municipalities are increasingly relying on connected technologies for their physical infrastructure. Here are some prominent examples of OT and IoT systems and devices:

OT systems control:

IoT devices measure:

These systems are essential for public safety and daily services – but many were built without cybersecurity in mind. Outdated setups, lack of network segmentation and outsourced management leave many municipal networks exposed to attacks, failures or even sabotage.

What can go wrong in unsecured public networks

Ransomware

Can shut down bridges, traffic systems or crowd control — disrupting daily life and public safety.

Unsecured access

Poorly secured SCADA or PLC systems can be exploited to disrupt water treatment, shut down heating in public buildings or interfere with public transport.

Loss of data or control

A compromised OT system leads to service disruption, loss of public trust and even social unrest.

Compliance with new regulations

NIS2 and similar laws demand proof of strong cybersecurity or risk penalties and reputational damage.
