Reduce Risk
- Identify potential OT exposure
- Evaluate remote access architectures
- Assess cybersecurity vulnerabilities
- Recommend practical risk-reduction strategies
Protect Critical Operations From Escalating Cyber Threats
Water and wastewater utilities are now facing intentional, targeted cyberattacks against OT and ICS systems. Attackers are using simple, repeatable, browser‑based tools to identify open ports, default passwords, and misconfigured remote access on systems that remain exposed to the public internet. For utilities that rely heavily on remote access for operators, contractors, and integrators, any weak or outdated configuration becomes an immediate vulnerability and one of the most frequent ways to attack systems.
The Modernization Gap
Many of these utilities run on infrastructure not built for today's threat landscape. Legacy PLCs, HMIs, networking gear, and remote connections frequently lack:
-
Modern authentication and centralized access control
-
Effective network segmentation and secure remote architecture
-
Security updates and lifecycle-managed firmware
As these systems age, vulnerabilities multiply. Closing this modernization gap is a practical, necessary step to reduce risk and secure long-term operations.

OT Security for Water Wastewater Facilities
This webcast highlights the importance of valuable partnerships throughout automation journeys especially in the water/wastewater utility industry.
It's our responsibility to collaborate together to protect critical infrastructure like water, wastewater, and cybersecurity.
Protect What Keeps Your Community Running
As a System Integrator, you are your utility customers' most trusted advisor. While municipalities recognize the threat, many do not see how exposed their aging architecture and unmanaged remote access have left them. Cybersecurity is no longer just an IT concern, it is a core matter of operational reliability and system modernization.
ISN works directly alongside municialities, local utilities, and System Integrators to tackle infrastructure and security challenges with proven technology and clear operational expertise:
-
Reduce Risk: Pinpoint all exposed OT assets, evaluate remote access security, and implement practical, high-impact risk mitigation strategies.
-
Modernize with Confidence: Assess aging PLC and HMI platforms, build structured migration roadmaps, and upgrade network architecture.
-
Support Secure Operations: Connect facilities safely, provide secure access for operators, and align your systems with current compliance frameworks.
