Cybersecurity for Water & Wastewater Utilities

Water and wastewater utilities face serious cybersecurity threats but often struggle with a lack of resources to ensure a strong cybersecurity program. We help you maintain resilience and do more with less.

The Nozomi Networks platform helps water and wastewater utilities bolster cyber and operational resilience by automating asset inventory, calculating asset risk, prioritizing vulnerability management, detecting threats and anomalies, and assisting with incident response.

Top Cyber Challenges for Water & Wastewater Facilities 

Budget Constraints

Tightly controlled rate increases are earmarked to replace aging water and sewer pipes, not bolster cyber resilience.

Lack of Expertise

Especially at small municipal water systems, water districts typically can’t afford trained OT security staff to deal with cyber threats.

Poor Cyber Hygiene

Outdated equipment connected to the internet, default passwords and unpatched vulnerabilities are the norm.

High “Scare Factor”

Nation-state actors know they can exploit weak cyber defenses to cause disruption and gain notoriety without actually harming the water supply.
