AxoSyslog: the syslog-ng™ fork built by its original developers. Get secure, supported, binary-compatible log management with advanced observability, daily vulnerability scans, and enterprise-ready features.

AxoSyslog, our syslog-ng™ fork, simplifies its licensing by adopting a single, clear open source license: GNU General Public License version 3 or later (GPL-3.0-or-later)

Open source tools have been used to implement data collection to feed SIEM and other security systems for decades. We at Axoflow feel that these existing deployments of open source technologies play an important role in the future data supply chains as well.
