The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Water utilities depend on distributed operational technology across source-water intake, treatment and chemical dosing, pumping and storage, distribution and metering, wastewater operations, and physical security. Long asset lifecycles, remote sites, vendor access, and uneven visibility can make legitimate connectivity difficult to govern. Cybersecurity must reduce risk without interrupting safe, continuous service.
Cisco® industrial switches and routers, combined with Cisco Cyber Vision, provide a network-integrated foundation for securing water operations—continuously identifying OT assets, assessing risk, and turning process context into actionable security policy. Comprehensive asset visibility, AI-assisted segmentation, secure remote access, and integrations across Cisco and Splunk give operations, IT, and security teams a shared view from source water through wastewater.
How Cisco Cyber Vision helps secure water utility operations
Cisco Cyber Vision gives operations, IT, and cybersecurity teams a common understanding of OT inventory, risk, and communications. AI-assisted grouping and policy recommendations help design segmentation, while simulation shows potential impact before enforcement. Cisco Cyber Vision provides zero-trust remote access to specific OT assets when needed. Asset, vulnerability, activity, and security-event telemetry can be operationalized in Cisco Extended Detection and Response (Cisco XDR) and Splunk for dashboards, correlation, investigation, and response.

● Comprehensive visibility:
See sanctioned and unsanctioned assets, communications, and remote-access paths across plants and remote sites.
● Current, risk-informed inventory:
Maintain asset profiles with identity, firmware, vulnerabilities, behavior, and prioritized risk context.
● Network-native protection:
Use compatible industrial switches and routers for OT sensing and enforcement without a separate visibility network.
● Controlled remote access:
Give employees, integrators, and vendors least-privileged, time-bound access to authorized OT assets.
● Unified IT/OT operations:
Share operational context with Cisco and Splunk workflows for correlation, investigation, and response.

Create a protected, resilient, and controlled foundation for water operations
Secure the OT infrastructure that supports safe, continuous water service.
Keep critical sites connected
Build resilient connectivity across plants, pump stations, storage facilities, and remote sites using ruggedized switching, redundant paths, and appropriate uplinks.
Know what is connected—and at risk
Identify OT assets from source water through wastewater, identify their vulnerabilities and risk, and map communications without disrupting the process.
Protect operations by restricting communications
Use observed communications and AI-assisted recommendations to create process-informed zones. Simulate proposed rules before enforcing boundaries.
Control remote access
Provision identity- and context-based access to named OT assets with MFA/SSO, schedules, approvals, and auditable sessions—without broad network reach.
Align operations, IT, and cybersecurity
Give stakeholders a shared understanding of OT assets, risk, and activity. Bring OT context into Cisco and Splunk workflows for detection, investigation, and response.
● Greater resilience across plants, pump stations and remote sites
● Continuous visibility into connected assets, communications, and risk
● Smaller blast radius through process-informed segmentation
● Safer, auditable access for operators, integrators, and equipment vendors
● Faster, coordinated response across operations, IT, and cybersecurity
