While capabilities continue to evolve, several platforms have become common within utility, industrial, and critical infrastructure environments.
 
== Executive Summary ==
 
Operational Technology (OT) Asset Visibility platforms have become foundational capabilities for utility cybersecurity, operational resilience, and asset management programs. As industrial environments become more connected, organizations require accurate visibility into assets, communications, software, and network behavior across generation, transmission, distribution, and critical infrastructure environments.
 
Modern OT visibility platforms provide continuous asset discovery, protocol awareness, behavioral analysis, and integration with security operations tools. These capabilities help organizations improve situational awareness, reduce cybersecurity risk, and support operational decision-making.

== Industry Context ==
No single platform is universally "best." Utility organizations typically evaluate solutions based on:


Industrial control systems were historically designed for reliability and availability rather than cybersecurity. As utilities continue integrating modern technologies, remote connectivity, cloud services, distributed energy resources, and vendor support services, maintaining visibility across OT environments has become increasingly important.
* OT protocol coverage (DNP3, IEC 61850, Modbus, OPC, ICCP, etc.)
 
* Passive monitoring capabilities
Unlike traditional IT environments, OT networks often contain specialized devices, proprietary protocols, and legacy equipment that may be difficult to inventory and monitor through conventional security tools.
* Integration with existing security tools
 
* Asset inventory accuracy
Asset visibility platforms provide a continuously updated view of industrial environments without actively interacting with critical assets, helping organizations improve awareness while minimizing operational risk.
* Threat detection maturity
* Scalability across substations and operational sites
* Cloud versus on-premise deployment requirements

== Core Capabilities ==
== Industry Trends ==
 
=== Asset Discovery ===


Asset visibility platforms use passive monitoring techniques to identify and inventory devices communicating across operational networks.
Several trends are shaping the OT visibility market:
 
Commonly discovered assets include:
 
* Programmable Logic Controllers (PLCs)
* Human Machine Interfaces (HMIs)
* Distributed Control Systems (DCS)
* Supervisory Control and Data Acquisition (SCADA) systems
* Intelligent Electronic Devices (IEDs)
* Workstations and servers
* Network infrastructure
 
'''Why It Matters'''
 
Organizations cannot effectively secure assets they do not know exist. Comprehensive inventories provide the foundation for cybersecurity, compliance, vulnerability management, and operational planning.
 
=== Asset Context & Intelligence ===
 
Beyond inventory management, modern platforms correlate multiple data sources to build operational context around assets and communications.
 
This may include:
 
* Industrial protocols
* Communications patterns
* Device relationships
* Software and firmware information
* Asset criticality
* Network dependencies
 
By understanding how assets communicate and interact, organizations can better prioritize cybersecurity risks and operational dependencies.
 
=== Behavioral Visibility ===
 
Many OT visibility platforms establish behavioral baselines by observing normal communications over time.
 
This allows organizations to identify:
 
* Unexpected communications
* Unauthorized devices
* Configuration changes
* Abnormal protocol activity
* Potential cyber threats
 
Behavioral analysis helps security and operations teams identify issues that may not be detected through inventory data alone.
 
=== Security Operations Integration ===
 
OT visibility platforms are increasingly integrated with enterprise security operations programs.
 
Common integrations include:
 
* Splunk
* Microsoft Sentinel
* IBM QRadar
* ServiceNow
* Palo Alto Networks
* CrowdStrike
* Cisco XDR
 
These integrations allow asset intelligence and operational context to be incorporated into broader security monitoring and response workflows.
