GRÜN VEWA: sovereignty score and 8 European alternatives

GRÜN VEWA is industry software from GRÜN Software Group for associations and federations, trade unions, parties and chambers, for charitable and fundraising organisations, and for training and seminar providers. The software family offers membership management, donation and fundraising management, and seminar and event management, and according to the vendor it also serves as the organisation's central ERP and CRM system. For SAP environments the company offers separate solutions under the name GRÜN MFplus.

GRÜN Software Group GmbH heads the GRÜN group and is based in Aachen, Germany; its website names no parent company. The vendor offers to run all its software in the central GRÜN App Cloud as IT outsourcing and states that all its data centres are in Germany, including Aachen and Düren. The product page does not say whether installation in your own environment is possible; ask the vendor. For European organisations that process member lists and donor data, the relevant point is that vendor hosting takes place in Germany.

Why digital sovereignty matters with GRÜN VEWA

GRÜN VEWA is headquartered in DE 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 GRÜN VEWA scores best on data residency.

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