How Water Utilities Are Building Stronger Cybersecurity Through Collaboration

For water utilities, open channels of communication are proving to be one of the most effective defenses against an increasingly hostile cybersecurity landscape.

The water sector carries a well-documented vulnerability: a significant portion of utilities continue to depend on aging operational infrastructure while operating with lean IT teams and limited dedicated cybersecurity personnel. Yet a pilot program jointly conducted by the Cyber Readiness Institute (CRI) and the Center on Cyber and Technology Innovation (CCTI) has demonstrated that coordinated, sector-wide incident response can meaningfully strengthen an organization's defensive posture.

The two-year initiative, which engaged 200 small and medium-sized water utilities, surfaced a critical operational insight: cybersecurity training alone is insufficient. To translate awareness into genuine resilience, organizations must pair education with robust, sustained support structures that accommodate the realities of resource-constrained environments.

The urgency of this challenge is underscored by a pattern of real-world incidents. In October 2024, American Water sustained a cyber-attack severe enough to disrupt its customer billing operations. That same year, a water utility in Texas fell victim to a separate intrusion, highlighting the sector's exposure across operational technology (OT) environments. The threat is not confined to North America: Norway and Poland have each reported comparable attacks on their water infrastructure, reinforcing that this is a global systemic challenge rather than an isolated regional concern.

The pilot program, sponsored by Microsoft, distilled its findings into four actionable recommendations for utilities seeking to strengthen their security frameworks. First, organizations should approach free cybersecurity tooling with caution, as such solutions frequently fall short of the functional depth required for effective threat management. Second, utilities must expand access to hands-on technical assistance, ensuring that implementation support keeps pace with the demands of deployment. Third, the program identified a structural gap in workforce development: cybersecurity competency should be formally integrated into operator licensing requirements, embedding security awareness at the professional credentialing level. Finally, utilities are encouraged to deepen their engagement with water sector associations, leveraging collective knowledge-sharing networks to elevate cybersecurity operations across the industry.

The program's concluding report frames the path forward as a fundamental strategic shift: utilities must move beyond passive information distribution toward active capacity building. Only by establishing resilient operational foundations — rather than simply disseminating guidance — can the sector reduce its exposure to future cybersecurity incidents and protect the critical infrastructure communities depend on.
