ICS Vulnerability Monitoring for Water and Wastewater Utilities
Monitor CISA ICS advisories and vendor vulnerability feeds for the OT systems inside your treatment plants, pumping stations, and distribution networks. Filtered alerts for Rockwell Automation, Siemens, Schneider Electric, AVEVA, Yokogawa, ABB, and other water sector vendors — matched to your watchlist, delivered by email.
Why Water Sector OT Security Is Different
Ageing SCADA Infrastructure
Water utilities run some of the oldest OT in any sector. PLCs and RTUs installed in the 1990s are still active in distribution networks — often running firmware that predates modern vulnerability disclosure processes. Vendors have issued patches; the challenge is knowing when they apply to you.
Remote and Unmanned Sites
Pumping stations, booster stations, and reservoir monitoring points are typically unmanned and connected over cellular or radio links. Remote access for maintenance expands the attack surface, and many sites lack the logging needed to detect intrusion.
AWIA and EPA Obligations
America's Water Infrastructure Act 2018 (AWIA) requires community water systems serving over 3,300 people to conduct risk and resilience assessments and certify emergency response plans. EPA guidance and CISA's water sector advisories are the primary technical reference for meeting those obligations.
Regulatory Context — Water Sector
America's Water Infrastructure Act requires community water systems serving more than 3,300 people to assess risks to their systems — including cyber risks to SCADA and control systems — and certify those assessments to the EPA. Vulnerability monitoring is a core component of demonstrating ongoing risk management. OTWarden supports the evidence requirements by logging every advisory matched to your watchlist.
The EPA's cybersecurity technical assistance program and its Incident Action Checklist for Water and Wastewater Utilities both reference CISA ICS-CERT advisories as a primary source of vulnerability intelligence. Tracking those advisories against your specific vendor assets — rather than reviewing every advisory manually — is the practical implementation of that guidance.
CISA regularly publishes ICS-CERT advisories covering vulnerabilities in control system products used across water treatment and distribution infrastructure — Rockwell FactoryTalk, Siemens SIMATIC, Schneider Electric EcoStruxure, AVEVA InTouch, and others. OTWarden monitors these advisories continuously and alerts you when one affects a vendor on your watchlist.

What OTWarden Monitors — and What It Doesn't
OTWarden monitors CISA ICS-CERT advisories, the National Vulnerability Database (NVD), and vendor-published security bulletins from Siemens ProductCERT, Rockwell Automation, Schneider Electric, and BSI. No network sensor or on-site agent is required — OTWarden works entirely from public advisory databases, matched to the vendor and product watchlist you configure.
Key vendors in water sector OT infrastructure that OTWarden covers:
FactoryTalk View, ControlLogix, MicroLogix, and Allen-Bradley PLCs are among the most common control platforms in water treatment and pumping applications.
SIMATIC S7 PLCs, WinCC SCADA, and TIA Portal are widely deployed in water infrastructure — particularly in larger municipal systems.
Modicon PLCs, EcoStruxure, and ATV drives appear throughout water and wastewater applications. Schneider publishes advisories through CISA and its own security portal.
InTouch HMI, System Platform, and Historian are common supervisory layers in water SCADA deployments. AVEVA advisories are tracked via CISA.
CENTUM VP and ProSafe-RS appear in larger water treatment plants, particularly in the UK and Asia-Pacific. Covered via NVD and CISA.
ABB RTUs, AC500 PLCs, and 800xA are used in water distribution telemetry and remote monitoring. ABB publishes advisories through CISA and its PSIRT portal.
You can also watch by sector — adding "water" as a sector watchlist entry matches any advisory CISA has tagged to the water and wastewater sector, regardless of vendor. Combine sector and vendor watches to get comprehensive coverage without irrelevant alerts.
Why OTWarden for Water Utility OT
Filtered to your assets
Set up a watchlist with the vendors in your water system — Rockwell, Siemens, Schneider, AVEVA — and only receive alerts that are relevant to you. No manual triage of every CISA advisory.
AWIA evidence trail
Every alert is logged with timestamp, CVE identifiers, CVSS score, and remediation guidance. Your alert history supports documentation of ongoing vulnerability monitoring for AWIA risk assessments.
No sensor required
OTWarden doesn't connect to your OT network. It monitors public advisory databases and vendor feeds. That means no OT network exposure, no firewall changes, and no agent to maintain.
Immediate gap analysis
When you add vendors to your watchlist, OTWarden retroactively checks the last 30 days of advisories — so you can see what your team may have missed before you signed up.
"Water and wastewater OT runs some of the oldest control hardware in any critical infrastructure sector. When a CISA advisory drops for a Rockwell ControlLogix or a Schneider Modicon — the kind of hardware sitting in pumping stations and treatment plants — the people who need to know about it are often the last to find out. OTWarden is the monitoring layer that should have existed already."
Free 14-day trial — no card required
Add the vendors in your water system — Rockwell, Siemens, Schneider, AVEVA — and receive filtered alerts from CISA, vendor feeds, and NVD as soon as a relevant advisory is published.
