Dimension by dimension
| Dimension | Hitachi Systems | NTT DATA |
|---|---|---|
| Staying power of the core product | Hitachi Systems is rated hard to displace, running SOC and managed security work for governments and banks inside the Hitachi group. | NTT DATA is rated defensible for now, as commodity delivery and BPO work erodes under AI coding agents. |
| Exposure to AI | AI partly touches Hitachi Systems services, mainly in the more standardized parts of its IT and security work. | AI partly touches NTT DATA too, and it is already cutting into the delivery and BPO side of the business. |
| How easily a giant copies them | Hitachi Systems is marked as blocked from being copied by a larger rival. | NTT DATA is marked as possible to copy, leaving it more open to being replicated by bigger players. |
| Pressure from rivals | Hitachi Systems faces lighter competitive pressure, with NTT DATA itself gaining ground in Japanese cyber and managed services. | NTT DATA faces heavier direct pressure than Hitachi Systems, squeezed by Accenture, TCS, Cognizant, Infosys, and Wipro, and has cut US headcount 24% since 2023. |
| Financial footing | Hitachi Systems posted Y672,169 million in FY2025 sales with 20,947 employees, backed by parent Hitachi Ltd's record Y10,586.7 billion revenue, up 8% year over year. | NTT DATA reports $30 billion plus in self-described annual revenue, with parent NTT Inc posting Y14,409.1 billion in consolidated operating revenue, up 5.1% year over year. |
| Defensive strength of the business | Hitachi Systems' defensive strength rests on its government and banking security work within the Hitachi group, backed by parent Hitachi Ltd's record FY2025 revenue, assessed July 2026. | NTT DATA's defensive strength rests on its scale and its backing from parent NTT Inc, whose consolidated operating revenue rose 5.1% year over year, assessed July 2026. |
