Overview

cidaas is a Germany-based European company building authentication and developer tools software. As an EU-headquartered provider, cidaas likely operates under GDPR, though EU Alts has not yet independently verified its ownership and hosting facts, so its exposure to the US CLOUD Act isn't confirmed yet — see the Details section below for what's known so far.

Why European teams pick cidaas

Teams in Europe consider cidaas when they want a authentication provider that bills in EUR and keeps customer data under Germany law. Its EU headquarters is a good sign compared with Auth0 and Okta, but EU Alts hasn't yet verified cidaas's ownership and hosting facts — check back once verification is complete.

Frequently asked questions

What is cidaas?

cidaas is a European cloud identity & access management platform operated by cidaas by Widas ID GmbH in Germany. It covers IAM, CIAM, identity verification and authorization from a single platform, and is hosted exclusively in the EU with dedicated German data centre options for sectors with heightened compliance requirements. Positioned as a full-feature replacement for Auth0 and Okta for EU data controllers.

What does cidaas do?

cidaas is german cloud identity and access management (ciam) platform — made and hosted in germany, with dedicated german server locations for regulated sectors. It is listed under authentication and developer tools on EU Alts because its core functionality serves teams looking for a European authentication tool with EU data residency, typically as a switch away from Auth0 and Okta.

Is cidaas a good European authentication alternative?

cidaas is a fit for European businesses evaluating authentication options where data residency and GDPR alignment matter — typical buyers include EU-based SaaS teams, public-sector projects, regulated industries (healthcare, finance, legal), and any organisation that needs to demonstrate that customer data does not leave the EU. It also overlaps with developer tools use cases.

Is cidaas GDPR compliant?

cidaas is headquartered in Germany and falls under EU jurisdiction, so it likely processes user data under the GDPR by default. Customer data processing is supervised by Germany's data protection authority, the Bundesbeauftragte für den Datenschutz und die Informationsfreiheit (BfDI). EU Alts has not yet independently verified cidaas's ownership structure or hosting location, so we can't yet confirm its exposure to the US CLOUD Act the way we can for verified entries.

How do teams switch from Auth0 to cidaas?

Most teams considering a move from Auth0 and Okta to cidaas are drawn to its EU headquarters and authentication workflow fit. EU Alts hasn't yet verified cidaas's ownership and hosting facts, so treat any CLOUD Act or Schrems II conclusions as provisional until verification is complete. Plan a migration in stages regardless: export your data from the US incumbent, pilot cidaas with a small team, then move the rest once integration coverage is confirmed.

Where is cidaas based?

cidaas is headquartered in Germany. Its main website is https://www.cidaas.com.
