Bunker is a European sovereign cloud provider and Cloud Act alternative: managed cloud infrastructure hosted entirely in France, outside US jurisdiction. 100% open-source and fully portable . For businesses that need GDPR-compliant hosting: benefit from redundancy and disaster recovery on Bunker cloud. As you grow, you can migrate to a fully on-premise setup thanks to our open-source stack. Our philosophy: give businesses full control over their data and infrastructure, with European data sovereignty built in from day one.

Is my data really outside US jurisdiction?

Yes. Your data is hosted exclusively in France, in our own datacenters. We are a European company under EU law only. No Cloud Act, no FISA 702, no US government access. Our SOC team monitors your infrastructure 24/7 with end-to-end encryption.

Can I migrate from AWS/GCP/Azure?

Absolutely. Our team guides you through migrating from US hyperscalers to GDPR-compliant European infrastructure, without service interruption. We have already migrated dozens of companies off US clouds.

What SLA do you offer?

We guarantee a 99.9% SLA for our Pro and Enterprise plans, with automatic compensation in case of non-compliance. Our multi-datacenter redundant architecture ensures maximum availability.

How does support work?

Our technical team is available 24/7 for Pro and Enterprise customers. Guaranteed response time under 15 minutes. Email support for all customers, with an average response time of 2h.

What technologies do you use?

We exclusively use open source technologies: Kubernetes, PostgreSQL, Redis, Prometheus, Grafana, and more. This guarantees zero vendor lock-in and complete transparency on how your infrastructure works.
