Exostar Provides Secure Environment Technology for Fujitsu Japan Trusted Supply Chain Service

en.Wedoany.com Reported - Exostar, a provider of trusted, compliant, and secure business collaboration software for highly regulated industries such as aerospace and defense, life sciences, and healthcare, will provide the secure environment construction technology based on Exostar Managed on Microsoft 365™ for Fujitsu Limited's "Fujitsu Trusted Supply Chain Service." Launched by Fujitsu in Japan, this service enables organizations in Japan's defense and critical infrastructure sectors to benefit from a secure environment built on Exostar's expertise for collaboration, information sharing, and compliance support.

This collaboration is set against the backdrop of converging cybersecurity compliance requirements across allied supply chains. The U.S. Department of Defense's Cybersecurity Maturity Model Certification (CMMC) program establishes cybersecurity requirements for defense contractors handling Controlled Unclassified Information (CUI); CMMC, based on NIST SP 800-171, provides a framework for protecting CUI across the defense industrial base. Japan's Ministry of Defense and the Acquisition, Technology & Logistics Agency (ATLA) have introduced defense supplier information security requirements highly aligned with NIST 800-171, alongside the 2022 Economic Security Promotion Act. Multinational aerospace, defense, and critical infrastructure supply chains require a common layer of trust that satisfies both regulatory regimes.

Exostar is responsible for building the secure Microsoft 365 environment within Fujitsu's "Fujitsu Trusted Supply Chain Service," designed to protect sensitive information while streamlining collaboration across complex supplier ecosystems. The environment provides managed enclaves, along with centralized identity and access management, multi-factor authentication, partner onboarding, information sharing controls, and auditable activity logging. This managed environment helps organizations strengthen security and simplify compliance efforts through a shared responsibility model: customers inherit multiple technical security controls provided by Exostar while remaining responsible for organizational-level requirements such as policy, training, personnel, and physical security. Sensitive information remains within the managed enclaves rather than being distributed across uncontrolled systems.

Exostar's technology platform supports organizations within the U.S. defense industrial base through Microsoft GCC High enclaves with FedRAMP Moderate equivalency, a capability validated in the most stringent U.S. defense environments. This mature technology is integrated into services operated by Fujitsu on its ISMAP-registered infrastructure in Japan, providing customers with data residency and domestic operations.

Stuart Wilson, Senior Vice President of Products at Exostar, stated that Exostar is honored to provide the secure MM365 environment construction technology for Fujitsu's "Fujitsu Trusted Supply Chain Service." Through this partnership with Fujitsu, Exostar is helping Japanese organizations address these defense and critical infrastructure challenges, delivering proven solutions that combine secure collaboration, compliance support, and operational efficiency. This initiative reflects Exostar's commitment to strengthening supply chain security and supporting trusted collaboration under allied requirements.

Exostar has partnered with Fujitsu since 2019, when Fujitsu integrated Exostar's secure collaboration and identity capabilities into its Fort# Forum product, helping Japanese suppliers protect Controlled Unclassified Information in accordance with NIST SP 800-171. The latest technology provided for the "Fujitsu Trusted Supply Chain Service" builds on this foundation, extending the secure collaboration platform to a broader supplier community as cybersecurity requirements continue to evolve.

This initiative marks a broader shift in how allied nations protect their industrial bases: the United States, Japan, and their allied partners are raising the security bar for suppliers, and multinational programs require solutions that enable secure collaboration without adding unnecessary cross-border complexity while respecting each nation's data residency requirements. Exostar's platform—trusted by more than half of the U.S. defense industrial base—and its integration with Fujitsu's domestic infrastructure provide a solid foundation for collaboration, information sharing, and compliance readiness across allied supply chains.
