ERIQ: sovereignty score and 8 European alternatives

ERIQ is a service platform from Rey Technology AG for industrial IoT and IT. It offers remote access through the browser and through VPN based on OpenVPN, with a four-eyes principle, two-factor authentication and a log of all access. It also includes alarming, data collection via Modbus, OPC UA and MQTT among others, its own service portal, reporting, interfaces, access management, inventory, tasks, multiple instances and update management. For connectivity the maker supplies IoT gateways and IoT sensors, which accept only cryptographically signed firmware.

Rey Technology AG is based in Sirnach, Switzerland, and belongs to the Rey group, which also has a German company in Freiburg. According to the vendor, the ERIQ portal runs in the ReyCloud, in Swiss data centres whose operator Green is described as ISO 27001 certified. The vendor states that it complies with the Swiss FADP and the GDPR. Switzerland is not an EU member but an EFTA country with an EU adequacy decision. The website does not mention a fully self-hosted portal; ask the vendor about this.

Why digital sovereignty matters with ERIQ

ERIQ 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.

ERIQ 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.

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