SOWL: sovereignty score and 8 European alternatives

SOWL is a platform from esatus AG for issuing, verifying and using digital credentials. It connects existing IAM, KYC and line-of-business systems with wallets, including the EUDI Wallet. According to the vendor it consists of components such as Issuer, Verifier and Core that can be integrated independently, and it uses open protocols such as OpenID4VCI and OpenID4VP with formats like SD-JWT and mdoc. Credentials stay in the user's wallet and are not stored centrally. Swiss swiyu and GLEIF vLEI are also mentioned. esatus appears in the TeleTrusT "IT Security made in Germany" register.

esatus is headquartered in Langen (Hesse), Germany, with a Swiss subsidiary in Lucerne; no parent company is named. The pages consulted do not state whether SOWL is delivered as a service or operated by the customer, nor where data is stored, so ask the vendor. The supplier falls under EU jurisdiction.

Why digital sovereignty matters with SOWL

SOWL 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 SOWL scores best on data residency.

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