e3 Centraya: sovereignty score and 8 European alternatives

e3 Centraya is a cloud access security broker (CASB) from e3 AG in Zurich. It encrypts data before it reaches cloud applications such as CRM, HR or service management systems. According to the vendor, the key is held only by the customer, so the data stays unreadable for the cloud provider. Centraya can be integrated through a forward proxy (ICAP), a reverse proxy, a mail gateway, an API gateway or a database driver. The Centraya AI edition encrypts sensitive information in prompts sent to AI services. e3 also offers managed services for rolling out and operating such security solutions.

e3 AG is headquartered in Switzerland, which is not an EU member but is an EFTA country with an EU adequacy decision. No foreign parent company is named on its website. Where Centraya runs, and where any data or metadata is processed, is not stated on the website and depends on the chosen integration. Ask e3 about the hosting location, key management and a data processing agreement. e3's privacy policy refers to Swiss data protection law and the GDPR.

Why digital sovereignty matters with e3 Centraya

e3 Centraya 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.

e3 Centraya 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.

e3 Centraya 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 e3 Centraya together with your other vendors and gives a total score, a heatmap and the main risk drivers.
