Redis Sovereignty: Beyond "Hosted in Switzerland"
Major managed Redis services — Amazon ElastiCache, Azure Cache for Redis, Google Cloud Memorystore, Redis Cloud — run on US-owned infrastructure under US law. Your cached data, session tokens, and real-time streams are accessible under the CLOUD Act without Swiss judicial process.
Running Redis on Swiss infrastructure solves the data residency question — but sovereignty is more than where data is stored. The EU Cloud Sovereignty Framework defines eight dimensions that determine whether your provider is truly sovereign.
Redis and the licence question
Redis changed its licence from BSD to a dual licence (RSALv2 + SSPLv1) in March 2024, restricting how cloud providers can offer Redis as a managed service. This licence change triggered the creation of Valkey, a fully open-source fork under the Linux Foundation.
VSHN operates both Redis and Valkey on Swiss infrastructure. For customers who need Redis specifically (compatibility with Redis modules, existing contracts, or Redis Stack features), we provide managed Redis under a commercial agreement. For customers who prioritise open-source licensing, we recommend Valkey as a sovereign alternative.
Regardless of which engine you choose, VSHN's Swiss ownership and operations provide the same sovereignty guarantees.
Redis sovereignty compared
| Dimension | Amazon ElastiCache | Redis Cloud | VSHN Managed Redis |
|---|---|---|---|
| Ownership | Amazon (USA) | Redis Ltd. (USA) | VSHN AG (Switzerland) |
| Governing law | US law | US law | Swiss law |
| CLOUD Act | Exposed | Exposed | Not exposed |
| Data location | AWS EU regions available | GCP/AWS EU regions | Switzerland (cloudscale.ch, Exoscale, or your choice) |
| Source code | Proprietary service layer | RSALv2 + SSPLv1 | Redis (RSALv2 + SSPLv1) or Valkey (BSD) |
| Operations team | USA | USA/India | Switzerland (Swiss-only option) |
| Certifications | SOC 2, ISO 27001 | SOC 2 | ISO 27001, ISAE 3402 Type II |
VSHN sovereignty self-assessment
We applied the EU's Cloud Sovereignty Framework (v1.2.1, October 2025) to our own services. This framework was used to score providers in the EU's EUR 180M sovereign cloud tender in April 2026 — three pure-European providers achieved SEAL-3, while a consortium involving Google Cloud scored only SEAL-2.
This is a self-assessment, not a formal SEAL certification. We publish it for transparency so customers can evaluate our sovereignty profile using the same structured criteria the EU uses.
| # | Dimension | Weight | Assessment | Evidence |
|---|---|---|---|---|
| SOV-1 | Strategic | 15% | Strong | Swiss AG, no foreign parent, all shareholders Swiss citizens (Commercial Register) |
| SOV-2 | Legal | 10% | Strong | Swiss law (GTC), no CLOUD Act, EU adequacy decision |
| SOV-3 | Data & AI | 10% | Strong | Swiss DCs by default. Sovereign key management via Managed OpenBao + Swiss HSM |
| SOV-4 | Operational | 15% | Strong | Swiss 24/7 ops, Swiss-only support option. All services on vanilla Kubernetes |
| SOV-5 | Supply Chain | 20% | Strong | Infrastructure-agnostic — customer chooses provider. Open-source software |
| SOV-6 | Technology | 15% | Strong | 100% open source. VSHN contributes to K8up (CNCF), Crossplane providers, Project Syn |
| SOV-7 | Security | 10% | Strong | ISO 27001, ISAE 3402 Type II, Swiss SOC. FINMA-regulated customers |
| SOV-8 | Environmental | 5% | Moderate | DC operators: Green Datacenter AG (ISO 22301/27001/27701), Exoscale sustainability. VSHN CSR policy |
Overall: SEAL-3 equivalent — the same level achieved by the winners of the EU's own sovereignty tender. No provider worldwide achieved SEAL-4, as it requires fully EU/EEA-sourced hardware supply chains and open-source foundations — structural gaps shared by every cloud provider.
