CPSMS: sovereignty score and 8 European alternatives

CPSMS is a Danish SMS gateway that lets organisations send and receive text messages through an API or a web-based sending system. The service is operated by Compaya A/S in Copenhagen, which has been active since 2001. The provider calls CPSMS a legacy platform and recommends its newer service SMS.dk for new projects. Existing customers can keep using it, and the provider lists automatic daily backups and SSL-encrypted connections among its features.

Compaya A/S is based in Copenhagen, Denmark, and is therefore a European company. According to the website, data is hosted on secure servers in Denmark, and the company obtains an independent annual GDPR review. The cpsms.dk site itself names only an ISAE 3402 certified data centre, without a country. The websites name no owner of Compaya A/S. For a European organisation this is a European option, but the provider's legacy status should be weighed in the decision.

Why digital sovereignty matters with CPSMS

CPSMS is headquartered in DK 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 CPSMS scores best on data residency.

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