The verdict in three sentences
Since the Privacy Shield was struck down (Schrems II ruling), hosting your European customers' data outside the EU creates a real GDPR risk, with fines reaching 4% of global revenue. Properly sized sovereign EU hosting costs between 180 and 3,000 EUR/year depending on traffic and service level. The real trap is not price but the actual location of data and backups, often unclear with US CDNs.
The three hosting tiers and their costs
| Hosting type | 2026 price | For whom | Typical SLA |
|---|---|---|---|
| Shared | 15 - 40 EUR/month | Brochure site, low traffic | 99.5% |
| VPS / managed cloud | 60 - 250 EUR/month | B2B site, CMS, medium traffic | 99.9% |
| Dedicated / cluster | 250 - 900 EUR/month | High traffic, heavy app | 99.95% |
| CDN + WAF | 25 - 90 EUR/month | Acceleration + security | 99.99% |
| Managed backups | 10 - 60 EUR/month | 30-day retention, restore | — |
A B2B institutional site runs well on managed cloud at 90-150 EUR/month with an EU CDN and daily backups, a 2026 ballpark of 1,500 to 2,500 EUR/year all in.
Comparison of compliant EU hosts
| Host | Location | Compliance | Managed price | Strength |
|---|---|---|---|---|
| OVHcloud | France (Roubaix, Gravelines) | GDPR, SecNumCloud (offers) | 70 - 200 EUR/month | Sovereignty, FR support |
| Scaleway | France (Paris, DC5) | GDPR, ISO 27001 | 60 - 180 EUR/month | Dev ecosystem, API |
| Vercel (EU region) | Frankfurt/Paris (edge) | GDPR if EU config | 80 - 250 EUR/month | Next.js performance, edge |
| Infomaniak | Switzerland (EU adequacy) | GDPR, carbon neutral | 50 - 160 EUR/month | Ecology, price |
For a Next.js site, Vercel EU region offers the best performance but requires locking the region to avoid any non-EU transfer. OVH SecNumCloud remains the reference for sensitive sectors (health, public, defense).
Mini case study
Sophie, DPO of a 900-employee industrial group in Lyon, discovers the corporate site is hosted on a US CDN with no location clause. The risk: form data transferred outside the EU, non-compliant with Schrems II. She migrates to managed OVH cloud at 130 EUR/month (1,560 EUR/year) with EU CDN and encrypted backups. One-off migration cost: 2,800 EUR. Against a theoretical GDPR fine of hundreds of thousands of euros, the total 4,360 EUR in year one legally secures 20,000 business contacts.

FAQ
Is French hosting mandatory to be GDPR-compliant?
No, hosting within the EU (or an adequacy country like Switzerland) is enough. What matters is that data neither transits nor is stored outside the EU without safeguards. Both France's OVH and Switzerland's Infomaniak qualify.
What does SecNumCloud certification change?
SecNumCloud is France's ANSSI label guaranteeing a trusted cloud immune to US extraterritorial laws (Cloud Act). It is often required for public tenders and sensitive sectors, at a 20 to 40% premium.
Can I use Vercel or Cloudflare and stay compliant?
Yes, provided you force EU regions and sign the standard contractual clauses. Without explicit configuration, these platforms may route traffic through the United States.
How much does a hosting migration cost?
A 2026 ballpark: 1,500 to 5,000 EUR depending on complexity (database, email, DNS, certificates). A planned migration happens with no visible downtime for visitors.
