IT and OT Services for Power & Utilities

Operational Technology (OT) security protects industrial control systems such as SCADA, DCS, PLCs, and historian systems that manage physical processes in power plants and utilities. Unlike IT systems, where a breach may result in data theft, an OT breach can lead to physical damage, power outages, and safety incidents. Traditional IT security tools often cannot be deployed on OT systems without risking operational disruption. ProArch applies OT-specific security frameworks, including NERC CIP and IEC 62443, and uses passive monitoring technologies to gain network visibility without impacting production systems.

NERC CIP (Critical Infrastructure Protection) is a mandatory set of cybersecurity standards developed by the North American Electric Reliability Corporation to protect the Bulk Electric System (BES). It applies to owners, operators, and users of bulk power transmission and generation assets operating at 100 kV or higher. NERC CIP covers 14 security standards spanning asset identification, access control, personnel training, incident response, physical security, and supply chain risk management. Non-compliance can result in significant fines enforced by NERC's regional entities.

ProArch gives power generation teams continuous, realtime visibility into their IT and OT environments showing what assets are connected, how data flows between systems, who is accessing them, and what has changed.

Working with ProArch, operators can detect issues earlier, reduce downtime, and make decisions with confidence instead of reacting after problems occur.

ProArch helps power plants manage third-party cyber risk by tightly controlling, monitoring, and documenting all vendor access to IT and OT systems.

We implement secure, timebound remote access, enforce least privilege credentials, continuously monitor vendor activity for malicious behavior, and maintain audit ready documentation aligned to NERC CIP requirements so vendors can do their jobs without introducing hidden risk to critical operations.

Yes. ProArch works with independent power producers and utilities to build data platforms that consolidate telemetry from assets and siloed systems into a unified analytics layer.

This enables AI-driven predictive maintenance — detecting equipment degradation patterns before they cause failures — as well as performance optimization, curtailment analysis, and compliance reporting. The result is reduced unplanned downtime, lower maintenance costs, and stronger market confidence.

ProArch provides an integrated portfolio of IT and OT services purpose-built for power generation and utility operations:

• OT Insights & Managed Services — Continuous OT monitoring, asset visibility, secure remote access, and compliance reporting
• IT/OT Managed Detection & Response — 24/7 SOC coverage across IT, OT, and IoT environments
• IT & OT Security — Network segmentation, threat detection, security assessments, and remediation
• NERC CIP Compliance — Gap assessments, documentation, audit preparation, and ongoing compliance support
• IT Refresh & Modernization — Infrastructure refresh, lifecycle management, patching, and operational support
• Cloud Transformation — Hybrid and cloud ready architectures to improve scalability, resilience, and cost control
• AI & Data Analytics — data strategy, AI predictive maintenance, performance monitoring, intelligent operational insights
• Vendor & Remote Access Management — Secure, governed third-party access across DCS, SCADA, and historian systems
• IT Transitions for M&A — Day1 operational continuity, system integration, and inherited risk reduction

ProArch helps power plant owners navigate M&A transitions by keeping operations running, securing and integrating IT and OT systems, eliminating inherited cyber risk, and modernizing infrastructure for scalable, future ready operations.

Our work focuses on Day1 readiness, risk reduction, and long-term operational resilience across critical infrastructure environments.

Yes. ProArch works alongside existing MSPs and OT vendors—including DCS, SCADA, and historian providers—acting as an integration and coordination layer rather than displacing them.

We manage access, documentation, security alignment, and escalation paths across all parties to ensure systems remain operational, secure, and compliant throughout the transition and beyond.
