Infrastructure you own, for missions you cannot outsource.
The problem
“Sovereign” cloud that still answers to someone else isn’t sovereign.
Foreign root access
An “EU region” of a US hyperscaler still sits under foreign jurisdiction. Under the US CLOUD Act, data residency is not the same as control.
Connectivity you cannot assume
Tactical and crisis operations run denied, degraded, intermittent or limited (DDIL). Infrastructure that needs constant reach-back to a central cloud is a vulnerability.
Vendor lock-in is strategic risk
Broadcom’s VMware repricing and closed-source relicensing turn your core infrastructure into someone else’s budget lever.
The definition
Digital sovereignty, defined honestly
Digital sovereignty means open code you can audit, software you self-host, and no foreign root access to your systems — not merely where the datacenter sits.
Open code
Auditable by construction. Control you can inspect, not a black box you must trust.
Self-hosted
Runs on your infrastructure — private cloud, on-prem, bare metal, air-gapped.
No foreign root access
No foreign vendor holds the keys, the control plane, or a legal backdoor.
The platform
One sovereign, open-source stack. Three ways in.
Built on CNCF-conformant open source and operated by your own cleared team.
Secure Operations
Air-gapped Kubernetes fleets from core to tactical edge, run by a small cleared team.

Sovereign VMs
Exit VMware/Broadcom without giving up your virtual machines. Keep the VMs, drop the licence hostage situation.

Secrets & Zero-Trust
Self-hosted, Kubernetes-native secrets management with no foreign vault dependency.
Explore →Operational scale
Built to run fleets, not pets.
Vendor figures from Kubermatic production deployments — your results depend on workload and environment.
Proof
Trusted where sovereignty is non-negotiable.
Swisscom runs a sovereign Kubernetes-as-a-Service on the underlying platform — 390 clusters, 2,100 worker nodes, 160 TB — with full in-country data residency. (Published CNCF case study.)
