ASPSMS: sovereignty score and 8 European alternatives

ASPSMS is an SMS gateway that lets websites, applications and e-mail systems send text messages, for example for two-factor authentication, notifications and broadcasts. The vendor recommends its WebAPI for new projects, alongside older REST and SOAP interfaces that remain operational but are no longer actively developed. An SMTP interface converts e-mails into SMS messages. The service is offered online, and customers buy credits to send messages.

ASPSMS is a product of VADIAN.NET AG, a Swiss internet and mobile solutions company founded in 1995 with its registered address in St. Gallen. VADIAN.NET AG states that it is ISO 27001 certified. The vendor says that customer data is subject to Swiss privacy law and that the product is developed and supported from Switzerland. The pages consulted name no hosting location or data centre and do not state GDPR compliance. A European organisation should obtain written confirmation of the storage location and processing terms before use.

Why digital sovereignty matters with ASPSMS

ASPSMS is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

ASPSMS hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

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