The UK Ministry of Defence's (MoD's) Single Information Environment (SInfoE) software component will be incorporated into the CSOC (Cyber and Specialist Operations Command) C2 (command-and-control) programme of record as the All-Domain Data Interoperability (ADDI) architecture, a defence source confirmed to Janes on 29 January.

SInfoE, and now ADDI, will provide a standardised protocol to enable information sharing between systems and architectures, according to the source.

Defence Science and Technology Laboratory (Dstl) and industry partners built the foundation of SInfoE architecture in 2021, according to Dstl's 7 January press release. SInfoE architecture enabled information to flow from where it originated to “a point of need”. In August 2025, Janes reported that Nexor Ltd developed SInfoE for the UK MoD under a Defence Condition (DEFCON) 703 contract. When asked about Nexor's role in the architecture development, the defence source said that SInfoE “utilised many different suppliers to develop and test the MoD owned protocols”.

In July 2024, SInfoE was tested during Archeron trials in which units of the Royal Navy, British Army, and Royal Air Force were integrated with unmanned systems from industry partners, according to Dstl. The trials showed “how SInfoE can help different military systems from different suppliers quickly share critical operational data”, as per the release. When asked whether the architecture has been fully integrated with specific platforms, the defence source said that the protocol was developed to be “relevant to all systems”. They added that it was designed to enable interoperability across all domains.
