syslog-ng: sovereignty score and 8 European alternatives

syslog-ng is an open-source log collection and routing daemon. Its primary author, Balázs Scheidler, began the project in 1998. It collects logs from servers, applications and network devices and forwards them to storage or analysis systems. The Open Source Edition is licensed under LGPL and GPLv2, while the Premium Edition adds plugins under a proprietary licence. Balabit, the original commercial sponsor, was acquired by One Identity in 2018, and the software is developed in One Identity's Budapest office.

One Identity LLC publishes the commercial edition and is headquartered in Aliso Viejo, California, which places the commercial owner under US jurisdiction. The open-source project also has a community of volunteers and a separate fork, AxoSyslog, which the original author launched in May 2024, so the licensing and governance of syslog-ng do not rest with a single company. Because the software runs on the organisation's own systems, log data stays under its control. For European organisations the Open Source Edition is a self-hosted option, while support and the Premium Edition come from a US-headquartered company.

Why digital sovereignty matters with syslog-ng

syslog-ng 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.

syslog-ng 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.

syslog-ng is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs syslog-ng together with your other vendors and gives a total score, a heatmap and the main risk drivers.
