The verdict in three sentences
Hosting your B2B prospects' data with a provider subject to US law weakens your GDPR compliance and your data sovereignty. Managed hosting in France/EU (OVH, Scaleway) costs 25 to 300 EUR/month and removes the risk of non-EU transfers. Full compliance — record of processing, DPA, security measures — budgets at 2,000 to 8,000 EUR and avoids regulatory fines that can reach several hundred thousand euros.
Sovereign hosting vs US cloud: the comparison
The hosting choice determines compliance. Here are the 2026 ranges for a B2B site.
| Criterion | OVH / Scaleway (EU) | US cloud (non-EU) |
|---|---|---|
| Data location | France / EU | USA + transfers |
| GDPR compliance | Native | Clauses + legal risk |
| Certifications | HDS, ISO 27001, SecNumCloud | ISO variable |
| Managed cost /month | 25-300 EUR | 30-400 EUR |
| Regulatory risk | Low | High (transfers) |
| Latency to France | < 20 ms | 80-150 ms |
For a B2B site collecting data through forms, sovereign hosting eliminates the main point of legal friction.
What GDPR compliance costs
Beyond hosting, compliance rests on verifiable documents and measures. Here are the 2026 items.
| Item | Budget 2026 | Recurrence | Obligation |
|---|---|---|---|
| Initial GDPR audit | 1,500-4,000 EUR | One-off | Recommended |
| Record of processing | Included in audit | Updated | Mandatory |
| DPA with processors | 0-1,000 EUR | Per contract | Mandatory |
| Compliant consent banner | 500-2,000 EUR | One-off | Mandatory |
| Managed EU hosting | 25-300 EUR/month | Monthly | Recommended |
| HDS certification (if health) | per provider | Annual | Sector-dependent |
Initial compliance for a standard B2B site sits between 2,000 and 8,000 EUR, excluding regulated sectors.

Mini case study
Emma, CFO/IT lead at a B2B services SME in Bordeaux (site collecting 400 leads/month via forms, data on a US cloud). An internal review reveals unframed non-EU transfers. She migrates to Scaleway managed hosting at 90 EUR/month and orders 5,500 EUR remediation: record of processing, DPA, compliant consent banner, encryption. In 5 weeks, the company removes its regulatory exposure and gains a sales argument: its large-account clients now require EU hosting in their tenders. Total annual cost: 1,080 EUR hosting + the amortized audit, versus a five-figure fine risk.
FAQ
Is the US cloud banned in 2026? No, but non-EU transfers must be framed by strict safeguards, and the legal framework remains unstable. EU hosting removes that uncertainty.
What is HDS certification? Health Data Hosting is mandatory for any site processing health data. OVH and Scaleway offer certified HDS plans.
Is the record of processing really mandatory? Yes, for any organization processing personal data. Its absence is one of the first breaches regulators flag during an audit.
What does serious managed hosting cost? From 25 EUR/month for a brochure site to 300 EUR/month for a high-traffic B2B site with backups, monitoring and CDN included.
Is GDPR compliance a sales argument? Increasingly: large accounts require EU hosting and a DPA in their tenders. Compliance is becoming a supplier selection criterion.
