cidaas: sovereignty score and 8 European alternatives

cidaas is a cloud identity and access management platform from Widas ID GmbH, part of the Widas Group. It covers customer identity (CIAM) as well as workforce identity (IAM) and offers single sign-on, passwordless and multifactor authentication, consent management, identity verification, authorisation and API security, based on standards such as OpenID Connect and OAuth 2.0. It is delivered as a cloud-native service that cidaas operates itself, for sectors such as retail, banking, insurance and energy.

cidaas is a German vendor. It states that the platform is made and hosted in Germany, using European data centres and infrastructure partners, and that it and its partners hold ISO 27001 certification. The owning group is the Widas Group, and no non-European parent company is named. The vendor does not describe an on-premises option, and cidaas is not presented as open source. For a European organisation this means a vendor-operated service under European jurisdiction, with personal data processed under a commissioned data processing agreement.

Why digital sovereignty matters with cidaas

cidaas is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so cidaas scores best on data residency.

cidaas is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs cidaas together with your other vendors and gives a total score, a heatmap and the main risk drivers.
