Summary
Government agencies and national security organizations require connectivity models that provide more than basic transport. They need private encrypted infrastructure, operational sovereignty, geographic control over data flows, and the ability to expand quickly as mission needs change.
Traditional approaches often relied on specialized appliances, complex licensing, costly hardware refreshes and manually engineered site-by-site designs. These models delivered control, but they also made secure networking expensive to scale, slow to adapt, and difficult to align with modern sovereignty and data-assurance requirements.
Fujitsu’s Graphiant-powered offering provides a different model. By combining Fujitsu’s trusted government delivery, integration, and operational expertise with Graphiant’s secure network fabric, agencies can build private networks that they own and control. The Graphiant control plane can be deployed in a government cloud or on premises, while Graphiant Data Assurance enables application-level geographic traffic boundaries. Sensitive applications can be kept within approved geographies, while other applications can access global services only through infrastructure located in approved allied countries.
The result is a secure, sovereign-ready connectivity model that allows Fujitsu to help government customers modernize faster, reduce cost and complexity, and retain the control required for sensitive public-sector and national security operations.

Creating Private, Encrypted Networks for Sensitive Government Missions
Government agencies that handle sensitive state data have historically required private, highly reliable connectivity across distributed sites, secure facilities, cloud environments, and operational locations. In traditional deployment models, this type of connectivity often depended on private circuits, specialized appliances, complex encryption overlays, and manually engineered site-by-site configurations. These approaches delivered control, but they were expensive, slow to deploy, and difficult to scale when agency requirements changed.
With Graphiant, Fujitsu is enabling government customers to build private encrypted networks using a secure network fabric designed for mission-critical connectivity. Agencies can create customer-owned private network environments,define how sites and applications connect, and operate with clear separation between traffic domains. This model supports the security and reliability requirements of sensitive government operations while reducing the complexity associated with traditional private network architectures.
For example, an agency connecting headquarters, regional offices, secure facilities, and cloud-based applications can use Fujitsu’s Graphiant-powered offering to establish encrypted private connectivity across all locations.Rather than treating each new site as a custom engineering project, Fujitsu can help activate connectivity through a repeatable service blueprint. New locations can be brought online quickly, policies can be applied consistently,and encrypted connectivity can be extended without redesigning the network.
This gives government customers the control and reliability they require while allowing Fujitsu to deliver secure connectivity faster, more consistently, and at significantly lower cost.
Preserving Infrastructure Ownership and Sovereign Operating Control
UK and EU government technology strategies increasingly emphasize trusted local providers, domestic control, and the ability to operate critical infrastructure within defined sovereign and regulatory boundaries.Historically, agencies often had to balance modern networking capabilities against concerns about vendor dependency, external control planes, specialized hardware, and limited visibility into how traffic was governed. For national security and sensitive public-sector environments, that tradeoff was difficult to accept.
Fujitsu’s Graphiant offering gives government customers a different operating model. Agencies can own the infrastructure that supports their private network, retain direct governance over the environment, and deploy the Graphiant control plane in a government cloud or on premises. These capabilities are related but distinct: infrastructure ownership supports accountability and operational control, while flexible control-plane deployment supports sovereignty, assurance, and alignment with agency-specific security architectures.
In practice, a government customer can choose to deploy the control plane in an approved government cloud environment or within its own premises,depending on its policy requirements and operating model. Fujitsu provides the deployment, integration, and operational expertise required to support the environment, while Graphiant provides the secure connectivity fabric that allows the agency to retain control over how the network is governed.
For Fujitsu’s government customers, the value is not only improved connectivity. It is the ability to modernize secure networking while preserving local control, trusted delivery, and ownership of critical infrastructure.
Enforcing Geographic Traffic Boundaries with Data Assurance
Government and national security organizations need to know not only that their traffic is encrypted, but also where it is allowed to flow. Historically,enforcing geographic boundaries for application traffic was difficult. Agencies often relied on static routing designs, complex regional segmentation, manual policy enforcement, or separate infrastructure stacks to keep sensitive applications within approved locations. This made the network harder to operate and increased the risk of inconsistent policy application.
With Graphiant Data Assurance, Fujitsu is enabling agencies to define geographic traffic boundaries at the application level. Sensitive application scan be prevented from leaving specific geographic regions, while other applications can be permitted to reach global destinations only through infrastructure located in approved allied countries. This allows agencies to align network behavior with national security policy, data sovereignty expectations, and mission-specific risk requirements.
Agencies often require one class of applications to remain entirely within the UK, another to operate across the UK and EU, and a third to access global resources only through infrastructure in allied countries. Fujitsu’s Graphiant-powered offering allows these policies to be defined and enforced through the secure network fabric rather than through a patchwork of manual routing rules and separate network designs. Different applications can follow different geographic policies while remaining part of a common private connectivity model.
By embedding geographic control into the network fabric, Fujitsu is helping agencies reduce operational burden, improve policy consistency, and support sovereign operating requirements across complex government environments.
Reducing Cost, Complexity, and Deployment Time
Secure government connectivity has traditionally been expensive to build and maintain. Agencies often had to purchase specialized hardware, manage costly refresh cycles, license features separately, and increase spend whenever they needed additional capability or bandwidth. These models created financial,operational, and procurement friction, particularly for agencies that needed to scale quickly or respond to changing mission requirements.
Fujitsu’s Graphiant-based offering is designed to simplify the economics and operations of secure networking. It can be up to 90% cheaper than similar solutions and deployed up to 4x faster by using commercial off-the-shelf hardware, reducing specialized appliance dependency, and simplifying the commercial model. Rather than requiring separate licenses or per-feature pricing, Graphiant provides all features in a single offering with a single subscription.
If a government customer needs to expand to a new office, secure facility, or operational site, Fujitsu can help activate the location without waiting for specialized hardware procurement or a lengthy circuit-and-license process. The agency can use COTS hardware, apply the appropriate connectivity and security policies, and bring the site into the private encrypted network in minutes. When additional bandwidth is needed, it can be increased through the portal without changing licenses or triggering a new feature entitlement process.
This commercial and operational simplicity lowers cost, accelerates deployment, reduces procurement friction, avoids expensive hardware refresh cycles, and gives agencies predictable access to the capabilities they need. For mission teams, secure connectivity can keep pace with operational requirements while preserving encryption, policy control, and infrastructure ownership.
