Prometeus: sovereignty score and 8 European alternatives

Prometeus, which also trades under the name iperweb, is an Italian hosting provider that says it has offered services since 1997. Its cloud offering iwStack is infrastructure as a service powered by CloudStack with hourly billing. Prometeus also sells SSD and Windows virtual servers, KVM servers, web hosting, and S3 object storage (iwSea) and cloud storage. All services are delivered as hosted services.

The website carries the copyright notice of CDLAN SPA, an IT company in Milan, and Prometeus names Milan as its headquarters. According to the website, its data centres are in Milan, Amsterdam and Bucharest, all within the EU. CloudStack, the platform behind iwStack, is open-source software, but the Prometeus service is a hosted offering rather than software you run yourself. The website does not describe the ownership structure; information on the ultimate owner can be found in CDLAN's company details. CDLAN is located at Via Caldera 21 in Milan.

Why digital sovereignty matters with Prometeus

Prometeus is headquartered in IT 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 Prometeus scores best on data residency.

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