GemWeb/CityWeb: sovereignty score and 8 European alternatives

GemWeb/CityWeb is a content management system with accompanying modules from Innovative Web AG (i-web) for the websites and eGovernment services of Swiss municipalities, cities and cantons. According to the vendor it combines a large set of basic modules for municipal content with optional extensions such as an online counter, payment and sealing functions, a central user account, a module for death and grave administration and a reservation system. i-web also provides software development, web design, hosting and support.

Innovative Web AG is a Swiss company with offices in Wilen bei Wollerau and Zurich. Since 2022 Swisscom, also Swiss, has been its majority shareholder, so there is no foreign parent. i-web lists hosting among its own services and its privacy statement refers to Swiss federal and cantonal data protection rules. Where the product's data is hosted is not stated on the product pages, so ask the vendor. Switzerland is not an EU member but an EFTA country with an EU adequacy decision. The product is aimed at the Swiss public sector.

Why digital sovereignty matters with GemWeb/CityWeb

GemWeb/CityWeb 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.

GemWeb/CityWeb 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.

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