Orange acquires Obvios’ Dome private 5G core technology

September 2, 2026 - 18:52

Orange has moved to bolster its secure connectivity offerings for government and enterprise clients by acquiring Dome, a private 5G core technology originally built by the French firm Obvios. The deal is aimed squarely at customers in defense, public safety, and critical infrastructure sectors, where control over data and network operations is a growing concern.

The Dome technology is designed to run as a standalone, private 5G core, meaning it can support dedicated networks that do not rely on public telecom infrastructure. For Orange, that fits neatly into a broader push toward sovereign digital services, where network ownership and data residency are non-negotiable for state-linked users. By bringing the core in-house, Orange gains more direct oversight over the software stack, which could shorten deployment times and allow for tighter integration with its existing secure offerings.

Obvios, the original developer, has been working on private network solutions for several years, but the technology will now live under Orange's umbrella. Financial terms of the acquisition were not disclosed. Orange has not said whether it will continue selling Dome to external operators or keep it strictly for its own managed services, though the latter seems more likely given the strategic framing.

The move comes as European telecom operators face mounting pressure to offer alternatives to non-European vendors for sensitive network functions. Orange has been vocal about the need for trusted, locally controlled technology, and this acquisition gives it another building block to point to. For customers in defense or emergency services, the pitch is straightforward: a 5G core that stays within French oversight, with no third-party involvement in the control plane.

Dome is not a full radio access network product, so Orange will still pair it with radio gear from other suppliers. But the core is often seen as the most sensitive part of a private network, since it handles authentication, routing, and policy. Owning that piece outright reduces supply chain risk and gives Orange more latitude to customize features for specific missions.

Industry watchers will be watching to see how quickly Orange can turn this into commercial contracts. Sovereign 5G has been a talking point for years, but actual deployments remain limited. With Dome in its portfolio, Orange now has a concrete answer for agencies that want private coverage without depending on foreign cloud or core software. Whether that translates into wins will depend on execution, but the strategic direction is clear.
