The verdict in three sentences
For a B2B site handling European prospect data, EU hosting (OVHcloud, Scaleway) removes the non-EU transfer risk and ticks the GDPR box with no legal engineering. A US cloud stays technically excellent but requires Standard Contractual Clauses (SCCs) and leaves you exposed to the Cloud Act, with a theoretical fine of up to 4 % of global turnover. On public tenders and enterprise accounts, sovereign hosting is often a knockout criterion: the extra cost is marginal, the risk avoided considerable.
Hosting comparison 2026
Monthly price is only part of the equation: what matters to a DPO is data location, reversibility and the legal basis for transfer.
| Criterion | EU (OVH, Scaleway) | US cloud (AWS, GCP, Azure) |
|---|---|---|
| Monthly price (B2B site) | 15 to 60 EUR/month | 20 to 80 EUR/month |
| Data location | EU guaranteed | EU region possible but Cloud Act |
| Transfer legal basis | None (data in EU) | SCCs + impact assessment |
| GDPR compliance | Native | Must be documented |
| EU public tenders | Often required | Often penalized |
| Reversibility | SecNumCloud available | Proprietary lock-in |
| Support language | EN + local | EN mostly |
The net billing gap is about 5 to 20 EUR/month; the real trade-off is legal exposure and tender access.
The regulatory risk quantified
Non-compliance is not just the theoretical maximum fine: regulators usually issue proportionate sanctions, but reputational damage and exclusion from public tenders cost far more.
| Scenario | 2026 exposure | Cost avoided with EU hosting |
|---|---|---|
| GDPR maximum fine | up to 4 % of global turnover | Risk neutralized |
| Common SME regulator fine | 5,000 to 50,000 EUR | Strongly reduced |
| Formal notice + remediation | 3,000 to 10,000 EUR advisory | Avoided |
| Lost public tender | 1 contract = 50,000 EUR+ | Criterion met |
| Undocumented non-EU transfer | Illegal without SCCs | Not applicable |
Mini case study
Sonia, DPO of a B2B digital-services SME, weighs a US cloud at 35 EUR/month against OVHcloud at 45 EUR/month. The premium is 120 EUR/year. By choosing sovereign hosting she removes the transfer impact assessment (saving ~4,000 EUR in legal advice), meets the sovereignty criterion of a regional tender worth 60,000 EUR and secures compliance. The return on those 120 EUR/year is immediate: one won tender funds ten years of hosting.

Is a US cloud EU region GDPR compliant?
Partially: data may sit in the EU, but the Cloud Act allows US authority access. You need SCCs and an impact assessment, i.e. 3,000 to 5,000 EUR of advisory.
What does sovereign hosting really cost?
Between 15 and 60 EUR/month in 2026 for a B2B site at OVHcloud or Scaleway, often 5 to 20 EUR/month more than an equivalent US cloud.
Is EU hosting mandatory for public tenders?
Not always legally, but it is frequently required or heavily favored, and lack of sovereignty can be disqualifying on sensitive tenders.
What fine does a non-compliant SME risk?
The GDPR ceiling is 4 % of global turnover, but common SME sanctions run 5,000 to 50,000 EUR, plus remediation and reputational impact.
What is SecNumCloud?
It is the ANSSI security visa for sovereign hosts, required for sensitive state data. Scaleway and OVHcloud offer qualified plans in 2026.
