NTT Docomo Business and Exawizards have launched a closed AI agent service, which runs AI systems within private, controlled environments rather than public internet networks.
This allows enterprises to use AI for tasks involving sensitive data while maintaining strict data governance and compliance — a capability that addresses growing demand from organizations that cannot expose proprietary or regulated information to external cloud platforms.
What happened
NTT Docomo Business and Exawizards have begun offering a "closed AI agent" service, a type of AI system designed to operate within controlled, private environments rather than on public internet infrastructure.
Why it matters
Closed AI agents allow enterprises to deploy AI that processes sensitive or proprietary data without exposing it to public cloud services, addressing data security and compliance concerns for businesses handling confidential information.
What to watch
The service targets organizations that require AI capabilities but cannot risk data leaving their internal systems — a segment may be particularly important for regulated industries and large Japanese enterprises handling customer or operational data.

The launch of a closed AI agent offering reflects a broader market shift toward on-premise and hybrid AI deployment models. Enterprises increasingly face regulatory requirements, data residency mandates, and competitive sensitivity that make cloud-based AI services risky for certain workloads. By partnering, NTT Docomo Business — a major telecommunications and IT services provider — and Exawizards are positioning themselves to capture demand from Japanese corporations that need AI capability but cannot tolerate the data exposure of public platforms. This approach contrasts with the current AI industry trend toward centralized, internet-connected models, suggesting that enterprises see material value in isolation and control.
