NTT Docomo Business has announced the launch of “Sekihi TEE,” a cloud service designed to securely process sensitive data and confidential algorithms without exposing them. Leveraging Trusted Execution Environment (TEE) and data sandbox technology, Sekihi TEE enables organizations to collaborate across industries without the risk of data leaks or unauthorized access.
The platform runs data and logic in a secure, hardware-encrypted space. This keeps information safe from outside access, even if data gets intercepted. Its workflow interface allows users to easily set up processing steps, approval flows, and notifications with a simple GUI. Processing needs consent from both data providers and logic owners. This stops misuse and keeps things clear.

By enabling secure cross-organizational data analysis without requiring full data disclosure, Sekihi TEE supports new collaborative use cases in sectors where privacy and confidentiality are paramount. The solution is offered under a pay-as-you-go plan and a monthly subscription, with NTT Docomo Business aiming to expand its integration with other services like SDPF for Healthcare. This launch reflects a broader trend toward privacy-preserving computing in enterprise and public-sector data ecosystems.
