== 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.
Supply chains have become a strategic focus area for utilities and critical infrastructure operators. Globally sourced hardware, software, and connected technologies introduce cybersecurity, operational, and geopolitical risks that can impact reliability, resilience, and business operations.


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.
At the same time, utilities are investing in advanced visibility and decision-support capabilities including Artificial Intelligence (AI), Supply Chain Control Towers, Digital Twins, and supplier-risk monitoring. These capabilities help organizations improve situational awareness, identify disruptions earlier, and strengthen long-term resilience.

For utilities, uncertainty surrounding deployed technologies can complicate asset management, cybersecurity monitoring, incident response, and overall operational awareness. The challenge is often less about a specific technology and more about understanding exactly what has been deployed and how it communicates.
 
=== Software Supply Chain Risk ===


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.
Modern utility operations depend on software vendors, cloud providers, embedded firmware, open-source components, and third-party integrators.


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.
A compromise of a trusted software supplier can potentially affect multiple organizations simultaneously. As software ecosystems grow increasingly complex, visibility into software dependencies becomes more important.


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.
EPRI's Technical Assessment Methodology (TAM) emphasizes evaluating attack surfaces, identifying security gaps, and validating security controls throughout technology deployments. <ref>[https://www.epri.com/research/programs/112046/results/3002021184 EPRI Technical Assessment Methodology (3002021184)]</ref> <ref>[https://www.epri.com/research/programs/112046/results/3002017149 EPRI Technical Assessment Methodology (3002017149)]</ref>
