Graylog: sovereignty score and 8 European alternatives

Graylog is a log management and SIEM platform for security, IT and audit teams. It began in 2009 as an open source log management project and grew into a full SIEM on the same codebase. It collects logs from many sources, groups related alerts into incidents, assembles investigation timelines and includes pre-built detection content. The product line comprises Graylog Open, Graylog Enterprise, Graylog Security and Graylog API Security. Graylog is available as Graylog Cloud, hosted by Graylog, and as a self-managed installation, including in air-gapped environments.

Graylog is headquartered in Houston, Texas, in the United States, with offices in London and in Hamburg (Graylog Germany GmbH). Graylog Open is free and self-managed under the Server Side Public License (SSPL), and Graylog itself describes it as source-available. The website does not state in which region Graylog Cloud runs. An organisation that wants to keep data within the EU can run the self-managed edition on its own infrastructure, which leaves the vendor's US jurisdiction relevant mainly to licensing and support.

Why digital sovereignty matters with Graylog

Graylog 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.

Data is hosted exclusively in the EU, so Graylog scores best on data residency.

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