Pyramid Research analysis, NTT Hits Light-Speed -- "NTT East, NTT West, and NTT Communications recently announced plans to spend an estimated JPY800bn (US$7.4bn) over the next five years to create the world's largest fiber optic network. Specifically, the NTT companies will upgrade 30m connections nationwide to fiber thereby allowing them to offer a wider array of value-added services on top of traditional voice. As Japan analyst Jane Buenaventura states, the justification for this expense is simple: survival in the increasingly competitive Japanese broadband market."
Enterprise AI adoption keeps running into the same wall: the moment sensitive data, model weights, or agent memory leave a tightly controlled environment, security teams lose visibility into what happens to them while the workload is actually running. Confidential computing exists to close that gap, and new research from ABI Research shows the technology has matured enough, across CPUs, GPUs, containers, and now agentic AI, to become a foundational requirement for enterprises building sovereign AI infrastructure: computing environments they control end to end rather than simply rent. Protection is Moving From CPUs to GPUs ABI Research finds that CPU-based confidential computing is closest to mass-market adoption, the product of years spent hardening chip-level isolation for general workloads. GPU-based confidential computing is now generating the strongest momentum, and for good reason. It addresses one of the largest unresolved gaps in AI security: protecting data and models while inf...
