VerneMQ: sovereignty score and 8 European alternatives

VerneMQ is an open-source MQTT message broker for IoT platforms and smart products, built on Erlang. The broker scales horizontally across a cluster of standard servers. Built-in plugins handle file-based authentication and authorisation, a Lua scripting engine connects to databases such as PostgreSQL, MySQL, MongoDB and Redis, and webhooks allow custom plugins in any language. It is self-hosted software that the operator installs on its own servers or cloud accounts, licensed under Apache 2.0.

The project is developed openly on GitHub. Commercial support, evaluation and customisation are offered by Octavo Labs AG in Brugg, Switzerland. Switzerland is a European country outside the EU. Because the broker is hosted by the organisation itself, data stays on infrastructure it controls and does not depend on a vendor cloud. For European organisations this keeps supplier dependency limited, although the choice of hosting location and the contract with the support partner still matter.

Why digital sovereignty matters with VerneMQ

VerneMQ is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

VerneMQ hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

VerneMQ is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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