The syslog-ng open source edition is the direct descendant of the syslog-ng project that started ten years ago. The application can operate in server or agent mode, and - apart from UDP - supports the reliable TCP protocol. That way syslog-ng can be used to create flexible and reliable logging infrastructure even in heterogeneous environments.
BalaBit offers commercial support for syslog-ng open source edition in the form of traditional support services and yearly subscription to binary packages (Web Store). Visit our support page for more information.
The open source community of syslog-ng can be tremendous help both for novice and advanced syslog-ng users.
