GDPR Hosting for a B2B Website: EU Compliance (2026)

The verdict in three sentences

GDPR-compliant hosting rests on three pillars: data located in the EU, a signed data processing agreement (DPA) with the host, and end-to-end TLS encryption. EU hosting with OVHcloud or Scaleway costs 30 to 200 EUR/month in 2026 and avoids data transfers outside the EU, the main point of friction with regulators. For sensitive sectors (health, defence, public finance), SecNumCloud qualification becomes a prerequisite.

EU host comparison 2026

The choice of host determines data sovereignty. European players guarantee EU location and a compliant DPA, unlike hyperscalers whose parent companies fall under extraterritorial legislation.

Hosting in a US hyperscaler's EU region is not enough: the parent remains subject to the Cloud Act. For a standard B2B site, a European player covers the need.

Regulator requirements and fines

Compliance does not stop at hosting: consent banner, records of processing and privacy policy are required. Fines are dissuasive.

The 4% of worldwide turnover ceiling (or 20M EUR) makes compliance non-negotiable, even for an SME.

Mini case study

Sophie, DPO of a financial services SME in Paris (120 staff), audits hosting before redesigning the corporate site. The site collects contact forms containing business data. She migrates from a US hyperscaler (EU region) to OVHcloud at 120 EUR/month, signs the DPA, enables TLS 1.3 and sets up a compliant consent banner. Total compliance cost: roughly 3,500 EUR of work + 120 EUR/month. Against a fine risk that could reach hundreds of thousands of euros, the return on investment is immediate.

FAQ

Is hosting in a US cloud's EU region enough? No. Even with EU-located servers, the US parent remains subject to the Cloud Act, which allows data access. For robust compliance, favour a European host.

What is a DPA and is it mandatory? The DPA (Data Processing Agreement) is the processing contract between you and the host. It is mandatory whenever a third party processes personal data on your behalf, under penalty of fines up to 4% of turnover.

Is SecNumCloud mandatory for everyone? No. This national security-agency qualification concerns sensitive sectors (health, critical operators, public administration). A standard commercial B2B site does not need it but can leverage it with large accounts.

How much does compliant hosting cost? In 2026, budget 30 to 200 EUR/month with a European player for a B2B site. Dedicated sovereign cloud rises to 200-800 EUR/month for critical needs.

Is the cookie banner really mandatory? Yes as soon as you set non-essential cookies (analytics, advertising). Refusal must be as easy as acceptance, otherwise the regulator can fine up to 2% of turnover.
