archTIS Trusted Data Integration (TDI) is a structured data integration and security policy orchestration solution designed for defence and supply chain environments. It enables organisations to ingest, consolidate, and govern sensitive and classified structured data from multiple distributed sources and formats. TDI applies Attribute-Based Access Control (ABAC) to enforce 'need to know' and 'need to share' principles across the data landscape. It uses a centralised policy authoring engine to create and apply access control and data protection policies, supporting both operational and analytical workloads. Key functional areas include: - Federated identity-based access decisions, where the same data is presented differently based on user identity - Real-time data orchestration from multiple sources and formats - Zero Trust data-centric security applied to structured data access - Management of IP, Export Control, and ITAR data based on access principles - Data augmentation to support access decisions - Self-serviceable data publishing - Comprehensive audit logging with built-in compliance observability and reporting TDI is designed to wrap security around existing services without interfering with them and to scale from edge deployments to hyperscale environments. It does not require specialised technology or compliance skills to operate and is intended to add policy-based access control to legacy systems as well as modern data environments.
