Malcolm is a powerful, easily deployable network traffic analysis tool suite for full packet capture artifacts (PCAP files), Zeek logs and Suricata alerts.
A user requested we look into accepting NetFlow v9 as a flow data source. I believe there are netflow inputs for logstash and filebeat already, so the plumbing is there. The majority of the work would be in normalizing the flow data to match, but there's a good chance that it's already going to be targeting ECS anyway.
