A municipal utility is a public service operator owned or run by a local government, such as a water, power, or wastewater provider. These organizations often deliver essential services that communities depend on every day, so their systems are treated as high-priority targets in cybersecurity.
In practice, municipal utilities matter because an outage, data leak, or loss of control can quickly affect public health, safety, and trust. Attackers may use ransomware, phishing, stolen credentials, or exposed remote access to disrupt business systems and pressure operators. Defenders focus on strong segmentation between IT and operational technology, offline backups, incident response planning, privileged access control, and tested recovery procedures. Because continuity expectations are high, even a limited compromise can create major operational and communications demands.
