TDC Software Launches "Nenoa," a Private AI Appliance for High-Security Environments

TDC Software Inc. (Headquarters: Chiyoda-ku, Tokyo; President and Representative Director: Hiroyoshi Kobayashi; hereinafter "the Company") will begin offering "Nenoa," a private AI appliance that operates entirely within an internal network, starting April 1, 2026. This product was developed for all types of companies and departments, particularly those in operational environments requiring strict security. With the slogan "Safe AI for every job," the service allows for the secure use of AI without an internet connection and can be easily implemented through a fixed monthly subscription without the need for large-scale infrastructure investment.

Background of Development As the use of generative AI in business expands rapidly, there is a growing need to utilize AI for tasks involving highly confidential information, such as customer data, contracts, internal documents, and source code. However, in operational environments handling sensitive data, there are many cases where cloud-based AI cannot be used due to security policies. In particular, for industries requiring strict information management—such as finance, healthcare, manufacturing, and government agencies—or in closed network environments where internet access is prohibited, cloud AI is physically inaccessible.

On the other hand, field challenges such as the risk of losing operational know-how due to the retirement of skilled staff and the need for operational efficiency due to chronic labor shortages are highly compatible with AI. Previously, there was an approach to building an on-premises AI environment from scratch, but the introduction of large GPU servers required initial investments ranging from tens of millions to hundreds of millions of yen, as well as specialized expertise, making the barrier to entry extremely high.

Overview of "Nenoa" "Nenoa" is a standalone hardware terminal equipped with a local LLM, AI chat, AI editor, and API integration. It can be put into operation immediately simply by connecting it to a power source and a network.

Six Features of "Nenoa" ・Structural Security The biggest differentiator of "Nenoa" is its design, which ensures "there is no path for data to leave the internal network." It realizes a mechanism where data leakage is physically and structurally impossible, and input data is not used for training the AI model.

・Ease of Implementation Because the environment necessary for AI execution is delivered fully built and verified, there is no need for the time and effort of server construction or software installation.

・Vendor-Neutral Model Selection It does not rely on any specific AI vendor and selects the optimal model from open-source LLMs.

・Cost Predictability With a fixed monthly fee and no API rate limits, no additional costs are incurred even with 24-hour continuous execution or bulk processing of large files.

・Small AI Terminal Eliminating Large-Scale Investment It does not require large-scale investment in massive GPU servers; by consolidating the AI execution environment into a small terminal, users can start utilizing AI on a small scale.

・Appliance-Type Subscription Rather than a one-time hardware purchase, it is provided as a fixed-rate monthly subscription that lowers the initial cost of the appliance, which integrates the software environment.

With the purpose of "Making the world smarter," our company supports the DX promotion of enterprises. Through Nenoa, we will provide an environment where companies and departments that have previously passed on AI adoption due to security concerns can safely utilize AI.
