Merox: sovereignty score and 8 European alternatives

Merox is a French DNS security and DMARC platform from Merox, a simplified joint-stock company in Montpellier, offered as a web service. It provides detailed DMARC reporting (RUA and RUF), a DNS security score, DNS monitoring with history, blacklist surveillance, a syntax validator with a setup wizard and domain detection. Supported standards include MTA-STS, DANE, DNSSEC, BIMI and Verified Mark Certificates. A free DNS checker and an API are also available. It is meant for organisations that want to monitor their email and domain security.

The company is based in Montpellier, France, and no foreign owner is stated. The legal notice names Microsoft Azure in France as the host, while the privacy policy does not name the provider and only says that data is processed on equipment located in the EU. Azure is supplied by a US company, which may matter when assessing jurisdiction. The privacy policy refers to the GDPR but does not mention a data processing agreement, so ask the vendor for one. No self-hosting option is mentioned.

Why digital sovereignty matters with Merox

Merox is headquartered in FR 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 Merox scores best on data residency.

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