The Jawn of the Month for October 2019 is Wazuh.
Wazuh is an open-source security platform that can work within enterprise environments.
Wazuh can help organizations utilize compliance required tools such as monitoring, threat detection, file integrity monitoring and intrusion detection. Normally these tools cost exuberant amounts of money for off the shelf products. This tool has the capability but will require installation, implementation and maintenance performed by your IT team. If you have the technical capability it is a no brainer to look for open-source tools.
This jawn is cool and it is free!
