BunkerWeb: sovereignty score and 8 European alternatives

BunkerWeb is an open-source web application firewall (WAF) that sits in front of web services and filters malicious HTTP traffic before it reaches the application. It can be installed on Linux, with Docker or on Kubernetes, and is also offered as a managed cloud service called BunkerWeb Cloud. The project publishes release candidates for its next version, so development is ongoing. Organisations can run the software on their own infrastructure and read its code.

Bunkerity SAS is a French company headquartered in Agen, and the BunkerWeb software is licensed under the AGPLv3. The company's own website is hosted by OVHcloud in France. For the managed cloud service, the cloud provider and the region are chosen on request, so a European organisation should confirm the hosting location in writing before relying on it. The self-hosted version runs without a vendor cloud, which keeps traffic and configuration under the operator's own control.

Why digital sovereignty matters with BunkerWeb

Data is hosted exclusively in the EU, so BunkerWeb scores best on data residency.

BunkerWeb 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 BunkerWeb together with your other vendors and gives a total score, a heatmap and the main risk drivers.
