BNGbox: sovereignty score and 8 European alternatives

BNGbox is software for a Broadband Network Gateway (BNG) from BISDN, aimed at broadband network operators. It runs as an application on a Kubernetes cluster of ordinary servers, as containerised network functions. Control plane and user plane are separated, following the Broadband Forum's TR-459 architecture, and sessions can be moved between user planes while running. Features include IPoE/DHCP and PPPoE, RADIUS, hierarchical QoS, BGP, a REST API and a CLI. BNGbox is assembled from open-source components such as Accel-ppp, ISC Kea, FRRouting, VPP/DPDK and FreeRADIUS.

BISDN GmbH is based in Berlin, Germany. No foreign parent company is named. BNGbox itself is not open source: the sources of the open-source components used are supplied, while BISDN's integration code stays with the company and can be deposited with a third party on request. The operator installs BNGbox on its own servers, so subscriber data stays in its own infrastructure; hosting by BISDN is not mentioned. Open interfaces and ordinary hardware limit dependence on a single manufacturer.

Why digital sovereignty matters with BNGbox

BNGbox is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

BNGbox runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

BNGbox is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

What this means for your organisation depends on your whole stack and context. The free assessment weighs BNGbox together with your other vendors and gives a total score, a heatmap and the main risk drivers.
