Bigbank: sovereignty score and 8 European alternatives

Bigbank is a digital bank that offers everyday accounts and payments, personal loans (consumer, home and credit cards), business financing, and term and savings deposits. Its website describes the group as providing digital financial services across Europe, with branches in Latvia, Finland, Sweden and Bulgaria alongside its Estonian base.

AS Bigbank is registered in Tartu, Estonia, and has held a banking licence there since 2005. Its shares are held by two Estonian individuals in equal parts, so no foreign parent company or non-EU owner is involved. The bank's principles for processing customer data are linked from its website, but the location of its systems and hosting providers is not stated on the pages reviewed. For a European organisation, the company is a bank under Estonian and EU supervision; the data hosting location should be confirmed directly with the bank before it is used for sensitive business finance.

Why digital sovereignty matters with Bigbank

Bigbank is headquartered in EE 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 Bigbank scores best on data residency.

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