European alternative to Auth0 and Okta: choosing a GDPR-compliant IAM
Auth0 and Okta are market leaders, but not always the best fit for a European company. Between GDPR compliance, per-user costs, and data sovereignty, it is worth evaluating a European alternative before you sign.
When looking for an alternative makes sense
Auth0 (now part of Okta) and Okta remain solid technical references. They become less suitable in a few scenarios common to European companies:
- You process personal data subject to GDPR and want to avoid transfers to third countries.
- You have a large user base and per-active-user costs grow unsustainably.
- You operate in sectors subject to NIS2 or data sovereignty requirements (public sector, healthcare, finance, utilities).
- You are a System Integrator or MSP managing many tenants with strong isolation needs.
The three criteria that really matter
1. Compliance and data sovereignty
The point is not whether a vendor is "GDPR compliant" on paper — nearly all claim to be — but where data resides and who can technically access it. A US vendor remains subject to non-EU laws even with European data centers. We explored this in our article on European IAM and data sovereignty.
2. Pricing model
Monthly active user (MAU) pricing is convenient at small volumes but becomes unpredictable at scale. A per-tenant/project license with unlimited users keeps costs predictable as you grow. See the details on our pricing page.
3. Multi-tenant isolation
For those managing multiple customers or projects, how data is separated between tenants matters. Per-tenant cryptographic isolation — where each tenant has its own key — is more robust than mere logical separation in the same database.
Quick comparison
| Criterion | Typical US platforms | European IAM (Tenant-Cloud) |
|---|---|---|
| Data residency | EU data center, non-EU parent | Data inside the customer Tenant |
| Vendor access | Technically possible | Encrypted/pseudonymized data only |
| Pricing | Per active user (MAU) | Per tenant/project, unlimited users |
| NIS2/GDPR compliance | On the customer | By-design |
How to run a serious evaluation
- Define compliance requirements before looking at features.
- Estimate cost at 12 and 36 months on your real volumes, not the entry plan.
- Ask for a demo on your use cases (SSO, MFA, provisioning), not a generic one.
- Check support: language, response times, presence in Europe.

Frequently asked questions
When you process GDPR-subject data and want to avoid non-EU transfers, when per-active-user costs grow too much, or when you operate in sectors subject to NIS2 and data sovereignty requirements.
Not at small volumes, but it becomes unpredictable at scale. A per-tenant/project license with unlimited users keeps costs predictable as the user base grows.
Yes, if the target platform supports open standards like SAML, OIDC and SCIM. LoginMaster supports them, so the migration does not tie you to a single vendor.
