Executive Summary

Cybersecurity has become one of the most pressing challenges for today’s utilities. As operators of critical infrastructure, utilities are prime targets for cyberattacks that can disrupt service, compromise customer trust, and trigger costly regulatory penalties. Threats have evolved far beyond simple viruses, now including ransomware, insider risks, and data manipulation aimed at undermining billing and operational accuracy.

Many utilities remain vulnerable due to fragmented meter data systems, relying on spreadsheets, paper logs, and disconnected databases that create gaps attackers can exploit. The stakes are high: financial losses in the millions, reputational damage, compliance fines, and even operational disruptions that jeopardize grid reliability.

This white paper examines the growing threat landscape, outlines the consequences of cyber breach, and explores how utilities can move from risk to resilience. It highlights best practices such as centralizing meter data, enforcing role-based access, and ensuring audit-ready reporting. It also showcases how solutions like TESCO’s Meter Manager Software provide utilities with a secure, centralized system of record that strengthens compliance, protects data integrity, and streamlines operations.

The path forward is clear: by modernizing meter data management and prioritizing cybersecurity, utilities can safeguard their systems, protect their customers, and build lasting confidence in an increasingly complex digital environment.
