Fujitsu on Aug. 20, 2026 launched a supply-chain information-sharing service in Japan designed for secure data exchange and communication within companies and across corporate networks, using functions from U.S.-based Exostar LLC, according to a company statement.
The service, called “Fujitsu Trusted Supply Chain Service,” complies with NIST SP 800-171, a U.S. National Institute of Standards and Technology cybersecurity standard for protecting controlled unclassified information handled by non-federal organizations. Fujitsu said the service is the first software-as-a-service offering in Japan to use Exostar’s functions and is aimed at companies with advanced security requirements, including those in the defense industry and critical infrastructure sectors.
The offering is intended to reduce the cost and operational burden of building and running individual high-security systems while allowing customers to pursue digitization in a secure environment, the company said.
Fujitsu has worked with Exostar since 2019 under an exclusive sales agreement for the Japanese market. The new service uses Exostar’s authentication and authorization functions and is delivered by Fujitsu for Japanese users.
Data management will be conducted at domestic data centers registered under ISMAP, a Japanese government system that evaluates and lists cloud services meeting official security requirements. Operations, including monitoring and support by Fujitsu specialists, will also be carried out in Japan. Fujitsu said the domestic operating model is intended to help minimize information disclosure risks under foreign laws.
The communication function is based on Microsoft 365. Fujitsu is also considering offering artificial-intelligence functions that can be used securely in coordination with Exostar.
At the same time, Fujitsu began offering a related service called “Fujitsu Trusted Supply Chain Service for U.S. CUI,” aimed at companies that need to meet U.S. regulatory requirements when handling controlled unclassified information, including businesses involved in transactions with the U.S. Department of Defense.
Fujitsu cited a tougher cyber threat environment and stricter supply-chain security requirements as the backdrop for the launch. The company said protection of design information, intellectual property and other sensitive data across supply chains has become an urgent management issue as attacks grow more sophisticated.
Japan has tightened economic security and defense-related information protection rules in recent years. Fujitsu said many of the security requirements in those regulations refer to NIST SP 800-171, making compliance with the standard an important condition for companies operating in fields with high confidentiality demands.
