The verdict in three sentences
A health insurer collecting health data and bank details through its enrolment forms must justify where that data is stored and who can access it, including any subcontractor subject to US law. Sovereign hosting in the EU costs EUR 15 to 120 a month for the brochure site, but certified sovereign and healthcare-grade offers often multiply the bill by 3 to 10. The right setup separates the low-sensitivity public site from the forms and member database, which go on the most demanding environment.
What sovereign, SecNumCloud-style and healthcare certifications mean
Three notions overlap, and the CIO must tell them apart:
- Data location: servers in the Netherlands or the EU. Necessary, but not sufficient if the host depends on a non-European parent company.
- Sovereign certification: France's SecNumCloud and the upcoming EU cloud certification scheme (EUCS) require immunity from extraterritorial laws. Few offers qualify, and Dutch insurers increasingly ask for equivalent guarantees.
- Healthcare security: in the Netherlands, NEN 7510 certification is the reference for any provider hosting health data, which covers medical questionnaires at enrolment.
The Dutch Data Protection Authority (Autoriteit Persoonsgegevens) also expects any transfer outside the EU to be documented in the processing register and the DPIA.
2026 comparison of hosting options
| Option | Example offer | Monthly cost (excl. VAT) | Stated SLA | Suited to |
|---|---|---|---|---|
| Managed EU hosting, static site | Scaleway, OVHcloud, Hetzner | EUR 15 to 40 | 99.9% | Public brochure site |
| Dedicated EU instances + managed database | OVHcloud Public Cloud, Scaleway | EUR 60 to 120 | 99.9 to 99.95% | Site + simple forms |
| NEN 7510 / healthcare-certified offer | Dutch healthcare hosting providers | EUR 250 to 900 | 99.95% | Forms with medical questionnaire |
| Certified sovereign offer | OVHcloud SecNumCloud, Outscale | EUR 800 to 3,500 | 99.99% | Member database, secure portal |
| Hyperscaler EU region | AWS, Azure, Google Cloud (Amsterdam) | EUR 50 to 400 | 99.99% | Non-sensitive scope, with legal review |
| 24/7 managed operations add-on | Provider or agency | EUR 400 to 1,500 | Per contract | Any production environment |
These figures are a 2026 order of magnitude for the web scope, excluding the core policy administration system.
Hidden costs to price before signing
| Item | What to check | Typical budget impact |
|---|---|---|
| Outbound bandwidth | Free, capped or billed per GB | EUR 0 to 90 a month for 1 TB |
| Backups | Retention, second-site storage, restore test | EUR 20 to 150 a month |
| 99.9% vs 99.99% SLA | 8 h 45 of downtime a year vs 53 minutes | Price multiplied by 2 to 4 |
| SLA penalties | Credit often capped at 10 to 30% of the monthly fee | Little real compensation |
| Non-EU transfer clauses | Support or subcontractors outside the EU | GDPR compliance risk |
| Reversibility | Data export, timelines, exit fees | EUR 1,500 to 6,000 migration |
The SLA gap is the most misleading: moving from 99.9% to 99.99% is only worth it for enrolment forms and the member portal, not for information pages.
Mini case study
Sanne, CIO of a 200,000-member health insurer in Amsterdam, receives 4,500 online enrolment requests a month during the switching season. Her site currently runs on a US hyperscaler with an embedded medical questionnaire.

Proposed setup: public site on managed EU hosting at EUR 35 a month, forms and questionnaires on a healthcare-certified offer at EUR 600, 24/7 managed operations at EUR 900. Total: EUR 1,535 a month, or EUR 18,420 a year, versus EUR 9,600 today. The EUR 8,820 annual premium should be weighed against a GDPR fine of up to 4% of turnover, and the loss of roughly 1% of enrolments per hour of downtime at peak season.
FAQ
Does the public site need sovereign certification?
Rarely. Information pages hold no sensitive personal data and can stay on managed EU hosting at EUR 15 to 40 a month. Only the forms and member database justify the most demanding environment.
Is healthcare certification required for a medical questionnaire?
In practice, yes, as soon as the host stores health data on the insurer's behalf. The premium is around EUR 200 to 800 a month compared with a standard offer.
Is a hyperscaler EU region enough?
Data location is respected, but the parent company remains subject to US law. For sensitive data, many insurers prefer a certified sovereign offer, more expensive but easier to defend before the regulator.
What is a 99.99% SLA really worth?
It allows 53 minutes of downtime a year, versus about 8 h 45 for 99.9%. Penalties are often capped at 10 to 30% of the monthly fee, hence the value of a redundant architecture.
How much does a migration to sovereign cloud cost?
Allow EUR 8,000 to 25,000 for the site and forms, over 6 to 10 weeks, with cut-over scheduled outside the enrolment season.
