Customer portals, mobile apps, and self-service channels must support everyday transactions while staying stable during outage peaks. For multi-company utility groups, modernization means moving from legacy platforms and fragmented journeys toward secure, scalable, cloud-enabled digital services that can handle high demand, payments, account access, and routine customer inquiries without adding operational strain
Digital modernization connects portal migration, native mobile performance, secure cloud foundations, and AI-enabled self-service — so customer experience improves without weakening operational control
Modern platforms help customer portals withstand thousands of users during outage events
Native implementation reduces crashes and navigation issues while improving performance and compatibility
Dynamic configuration enables real-time feature control with less dependency on app marketplace releases
AI-powered assistance handles high-volume, low-complexity inquiries and improves through customer feedback
NTTデータのサポート体制は?
NTT DATA migrates service websites from legacy portal environments to modern cloud-ready platforms supported by microservices and transactional web journeys

We evolve hybrid mobile ecosystems into native applications with shared core capabilities, configurable layers, and deeper device integration

Access controls, encryption, network isolation, identity management, and traffic protection strengthen customer-facing services

We don’t modernize channels in isolation. We build fallback, error-handling, governance, and QA practices around the journeys customers depend on most

Virtual assistance can be shaped around top call drivers, secure system integration, conversational flows, and continuous performance monitoring
