Energy and Utilities organizations need to strengthen cybersecurity across distributed plants and industrial sites, where legacy systems, remote access, third-party connectivity, and unmonitored OT traffic can increase exposure. The challenge is no longer only deploying controls — it is building a unified, risk-driven capability that combines visibility, prevention, secure access, continuous monitoring, and operational governance
An OT Cybersecurity Program turns scattered security initiatives into a managed resilience model — connecting assessment, roadmap, platform rollout, endpoint protection, secure access, and 24/7 OT-SOC operations
Build a continuously updated inventory of OT assets, communications, protocols, and operational dependencies
Align remediation with ISA/IEC 62443 principles, business criticality, feasibility, and site-specific constraints
Govern vendor, operator, and support-team access through approval workflows, strong authentication, traceability, and least privilege
OT-SOC services bring alert triage, incident handling, escalation, reporting, and continuous tuning into the operating model
How NTT DATA helps
NTT DATA evaluates technical and organizational gaps across architecture, segmentation, remote access, governance, roles, and operational practices

We define the target security model, operating procedures, service model, quick wins, and multi-year roadmap

We deploy and tune platforms for asset discovery, vulnerability management, network analysis, threat detection, and security operations integration

OT-optimized EDR and Secure Remote Access strengthen legacy hosts, vendor access, session traceability, and controlled maintenance support

We don’t leave OT security as a project. We embed OT-SOC monitoring, runbooks, SLAs, reporting, and continuous improvement into daily operations


Assessment report, risk register, and remediation backlog create shared priorities
Target architecture, security model, and rollout strategy define the approved transformation plan
OT security platforms, EDR policies, Secure Remote Access, and integrations create active protection capabilities
OT-SOC runbooks, SLA tracking, vulnerability governance, reports, and tuning keep resilience improving over time
