Mezmo: sovereignty score and 8 European alternatives

Mezmo, known as LogDNA until 2022, provides a platform for telemetry data and observability. It covers collecting, transforming and routing logs and other telemetry through pipelines, searching logs, and an agentic SRE capability built on the open-source AURA agent that, according to the vendor, helps investigate alerts and post-deployment regressions. It is aimed at engineering and operations teams. The service is delivered as SaaS; the AURA agent is available as open source on GitHub.

Mezmo Inc. is headquartered in San Jose, California, in the United States. According to its security page, the service runs in AWS data centres located in the United States; no EU region is mentioned. Mezmo states that it processes data in the US, self-certifies under the EU-US Data Privacy Framework and offers Standard Contractual Clauses in its data processing addendum. Logs can contain personal data. For a European organisation this means that data sits with a US vendor, so US legislation such as the CLOUD Act may apply.

Why digital sovereignty matters with Mezmo

Mezmo is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Mezmo hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

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