OT Visibility Platform Landscape
While capabilities continue to evolve, several platforms have become common within utility, industrial, and critical infrastructure environments.
| Platform | Primary Strengths | Common Utility Use Cases |
|---|---|---|
| Nozomi Networks | Deep OT protocol visibility, asset discovery, anomaly detection, vulnerability identification | Substations, generation facilities, transmission environments, network monitoring |
| Dragos | Asset inventory, threat detection, ICS threat intelligence, incident response support | OT security operations, threat hunting, industrial cyber defense |
| Claroty | Asset discovery, exposure management, risk analysis, secure remote access | Enterprise OT visibility and asset management programs |
| Microsoft Defender for IoT | Integration with Microsoft security ecosystem, agentless OT monitoring | Organizations using Microsoft Sentinel, Defender XDR, Azure environments |
| Armis | Agentless asset visibility, IT/OT convergence, vulnerability and exposure management | Enterprise-wide asset visibility across IT, OT, IoT, and medical devices |
Selection Considerations
No single platform is universally "best." Utility organizations typically evaluate solutions based on:
- OT protocol coverage (DNP3, IEC 61850, Modbus, OPC, ICCP, etc.)
- Passive monitoring capabilities
- Integration with existing security tools
- Asset inventory accuracy
- Threat detection maturity
- Scalability across substations and operational sites
- Cloud versus on-premise deployment requirements
Industry Trends
Several trends are shaping the OT visibility market:
| Trend | Description |
|---|---|
| IT/OT Convergence | Increased visibility across both enterprise and operational environments. |
| Exposure Management | Prioritization of exploitable vulnerabilities and operational risks. |
| AI-Assisted Analysis | Automated asset classification, alert triage, and risk identification. |
| Secure Remote Access | Improved management of vendor and contractor connectivity. |
| Grid Modernization | Increased visibility requirements driven by DER, IBR, and BESS deployments. |
