heyData: sovereignty score and 8 European alternatives

heyData is a compliance platform for data protection and information security. Its modules cover ISMS management, asset and vendor management, policies, data protection impact assessments, technical and organisational measures, data processing agreements, whistleblowing, training and audits. It addresses frameworks including ISO 27001, GDPR, NIS2 and the EU AI Act, and companies can add an external data protection officer service. The platform is a web application, combined with expert services, and is aimed at start-ups and mid-sized companies.

heyData GmbH is a German company with its registered seat in Berlin. The company's website states that its platform is operated in Germany and that customer data is hosted there. The vendor describes itself as a German company subject to European law, and states that non-EU authorities have no access; this is the vendor's own claim. The vendor names no parent company, so organisations should confirm ownership and sub-processors in the processing agreement.

Why digital sovereignty matters with heyData

heyData 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 heyData scores best on data residency.

heyData 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 heyData together with your other vendors and gives a total score, a heatmap and the main risk drivers.
