The verdict in three sentences
A wealth management firm that collects financial reviews online, whether in Bordeaux or Dublin, handles sensitive financial data: income, assets, family situation, sometimes health for protection products. Hosting in the EU with a European-owned provider (OVH, Scaleway, Outscale) costs 15 to 120 EUR excl. VAT a month and removes exposure to the US Cloud Act, for a price gap often under 30 EUR a month. The rest of GDPR compliance (records of processing, encryption, cookie banner, retention periods) takes a few days of work, compared with regulatory fines of up to 4% of global turnover.
France, EU or US provider: the real comparison
The question is not only where the servers sit but who owns the provider. A server in Frankfurt operated by a US company remains subject to the Cloud Act, which allows US authorities to request access to data. For an adviser whose clients are often business owners or professionals, this argument weighs on trust.
| Criterion | French provider (OVH, Scaleway) | Non-French EU provider | US provider (EU region) |
|---|---|---|---|
| Monthly price, brochure site + forms (excl. VAT, 2026 estimate) | 15 to 60 EUR | 20 to 70 EUR | 20 to 90 EUR |
| Price with encrypted database and backups | 50 to 120 EUR | 60 to 130 EUR | 60 to 150 EUR |
| Cloud Act exposure | No | No | Yes |
| SecNumCloud qualification possible | Yes (dedicated offers) | No | No |
| Non-EU transfer to document | No | No | Yes (DPF or standard clauses) |
| Local-language support | Yes | Variable | Variable |
| Sales argument with clients | Strong | Medium | Weak |
For a firm's website, the cost gap between European and US hosting is usually 0 to 30 EUR a month. The promise "your data stays in Europe" can be used directly on the contact page and in client onboarding documents.
The website's GDPR compliance budget
The items below are market orders of magnitude for an 8-adviser firm with a financial review form and a document upload area.
| Item | 2026 cost (excl. VAT, estimate) | Frequency |
|---|---|---|
| EU hosting with encrypted backups | 50 to 120 EUR | Monthly |
| Regulator-compliant cookie banner (SaaS) | 0 to 30 EUR | Monthly |
| Encryption of forms and attachments | 800 to 2,500 EUR | One-off |
| Records of processing and legal notices | 600 to 1,500 EUR | One-off, then updates |
| Retention policy and automatic purge | 500 to 1,200 EUR | One-off |
| Light security audit (scan, headers, TLS) | 800 to 2,000 EUR | Yearly |
| Cookieless or consent-exempt analytics | 0 to 20 EUR | Monthly |
Three points make the difference during an inspection. First, review forms must never travel by plain email: data is stored encrypted and the adviser simply gets a notification. Second, retention for unconverted prospects must be limited, 3 years after the last contact being the usual French regulator guidance. Third, analytics should be consent-exempt (configured Matomo, Plausible), which avoids losing 40 to 60% of measurements when visitors decline cookies.
Fines and concrete risks
Regulators (the CNIL in France, the Data Protection Commission in Ireland) can impose fines of up to 20 million euros or 4% of global turnover, but for a mid-sized firm the main risk lies elsewhere: a leak of financial reviews requires notification within 72 hours and informing clients. The reputational cost far exceeds the fine. Advisers also face scrutiny from their financial regulator (AMF in France, Central Bank of Ireland) on client data protection.
Mini case study
Laurent, head of an 8-adviser wealth management firm in Bordeaux (hypothetical persona), receives 40 review requests a month via his site, hosted so far with a US provider at 45 EUR a month, with forms sent by email.

- Migration to French hosting with an encrypted database: 85 EUR a month, or 480 EUR more per year.
- One-off compliance work (encryption, records, purge, banner): 4,200 EUR.
- Total cost over 3 years: 4,200 + 3 × 1,020 = 7,260 EUR.
With a 15% conversion rate and an average first-year fee of 2,500 EUR, only 2 additional clients over 3 years won over by "data hosted in France" are needed to cover the investment. Laurent adds the statement to every form and to his brochure.
FAQ
Is US hosting illegal for a wealth adviser?
No. The Data Privacy Framework allows transfers to certified companies, but it must be documented in the records of processing. EU hosting removes the issue for 0 to 30 EUR more a month.
How much does compliant hosting cost for a firm?
Between 15 and 120 EUR a month in 2026 depending on database, backups and encryption. An 8-adviser firm typically pays around 60 to 90 EUR.
Is a cookie banner mandatory?
Yes, as soon as a non-exempt tracker is set, with a "Reject all" button as visible as "Accept all". Compliant solutions cost 0 to 30 EUR a month.
How long can we keep prospect data?
French regulator guidance is 3 years from the last contact for a prospect. Client reviews then follow periods linked to the relationship and regulatory duties, often 5 years.
Do forms need encryption if the site uses HTTPS?
Yes. HTTPS protects data in transit, not at rest. Encrypting the database and attachments costs 800 to 2,500 EUR and greatly limits the impact of a breach.
