Model, analyze, and prioritize cyber risk in water treatment OT environments without disrupting real-time operations.
Municipal water treatment plants are a critical operational technology environment with demanding real-time constraints. They support essential public services and depend on interconnected SCADA, PLC, HMI, and sensor systems, often alongside legacy infrastructure that cannot tolerate disruptive cybersecurity practices. This creates a difficult challenge: organizations need deeper cyber insight, but traditional active scanning methods may introduce operational risk.
That challenge is the focus of our latest whitepaper, “Operational Technology (OT) Cybersecurity Compliance with ASSURANT™ Suite: Enhancing Cybersecurity for Municipal Water Treatment Plants with ASSURANT™ Suite.” The paper explains how ASSURANT extends beyond monitoring by helping organizations model their environments, analyze attack paths, evaluate risk, prioritize mitigations, and generate compliance-ready reporting for cyber-physical systems.
Many organizations already use strong open-source tools to improve visibility across OT and IT environments. Platforms such as Suricata, Sysmon with Winlogbeat, Logstash, Elasticsearch, Kibana, and Apache NiFi play an important role in monitoring logs, events, and network traffic. The whitepaper’s central point is that while these tools provide valuable visibility, organizations also need a way to understand how systems are connected, where attack paths exist, which vulnerabilities matter most, and how to document cybersecurity posture in a form that supports regulatory and operational requirements.
The whitepaper shows how ASSURANT addresses that gap through passive system modeling and visualization. By building a data-flow-based representation of the environment, ASSURANT helps teams uncover hidden dependencies, identify exposed interfaces, and visualize where vulnerabilities and mitigations exist across the system. In OT environments where uptime matters, that kind of passive analysis is especially valuable because it supports better decisions without forcing disruptive changes to live operations.
It also highlights advanced cyber analyses that help organizations move from reactive monitoring to proactive planning. These include compromised data analysis, compromised dependency analysis, target risk analysis, attack path clustering, and near-real-time vulnerability awareness based on newly published CVEs. Together, these capabilities help teams understand not just that something is vulnerable, but how that weakness could be exploited, what systems are at risk, and where mitigations may have the greatest operational impact.
Another major takeaway from the paper is mitigation optimization. Security teams rarely have unlimited time or budget, especially in municipal environments. The whitepaper explains how ASSURANT supports prioritization by correlating risk, mitigation cost, and expected effectiveness. That allows decision-makers to focus on the actions that can produce the best reduction in cyber risk for the resources available, rather than treating every finding as equally urgent.
The paper also presents compliance as an integral part of cybersecurity management, alongside vulnerability identification, mitigation, and reporting. ASSURANT is described as supporting reporting and documentation aligned to frameworks and standards such as SOC 2, ISO 27001, NERC CIP, and NIST 800-53 by tying modeled systems, vulnerabilities, controls, and mitigation data into auditable outputs. For organizations managing critical infrastructure, that can reduce manual reporting burden and improve traceability across cybersecurity activities.
To make the discussion concrete, the whitepaper walks through an illustrative use case centered on the Cranberry Water Treatment Plant in Westminster, Maryland. In that scenario, ASSURANT is shown supporting five phases: modeling the environment, documenting vulnerabilities and dependencies, analyzing threats, evaluating risks and mitigations, and generating compliance reports. Just as important, the paper presents ASSURANT as complementary to existing open-source tooling rather than a replacement for it.
The message is clear: municipal water treatment cybersecurity requires more than monitoring alone. It requires context, analysis, and a practical way to connect system architecture, cyber risk, and compliance evidence into a unified workflow. That is the value proposition this whitepaper presents, and it is why ASSURANT is well positioned to help organizations strengthen cyber resilience across complex OT environments.
