EM.EX: sovereignty score and 8 European alternatives

EM.EX is an event and guest management platform from EMENDO Event + Congress GmbH & Co. KG. It brings the processes around an event together on a single data foundation: invitations, registration with participant types and tickets with dependencies, communication, hotel and travel, ticket dispatch, check-in and badge printing, and evaluation. It also offers abstract and programme management with call for papers and review, stakeholder management for speakers and sponsors, invoicing with dunning and VAT handling, white labelling, e-mail campaigns, automations, seating plans and REST APIs with webhooks. The platform is multilingual and aimed at congresses, corporate events and agencies, among others.

EMENDO is based in Ostfildern, Germany; its website names no parent company in another country. The company says it handles both the development and the hosting of its guest management platforms. The website does not say where the servers are located; ask about this, and about the data processing agreement, because you process personal data of participants. For a European organisation this is a German provider without a named foreign parent company.

Why digital sovereignty matters with EM.EX

EM.EX 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 EM.EX scores best on data residency.

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