Malcolm vs Observer GigaStor

Malcolm is a network traffic analysis suite for security monitoring. It accepts PCAP files, Zeek logs, and Suricata alerts through a browser interface, and can also process live captures forwarded by lightweight sensors. OpenSearch Dashboards provides visualizations, while Arkime helps locate and identify network sessions. Malcolm adds context to session data with GeoIP, hardware manufacturer lookups, asset inventory mappings, and JA4 fingerprints. It analyzes documented protocols including DNS, HTTP, Modbus, and BACnet. Deployment uses Docker or Podman containers, with Kubernetes instructions for on-premises or AWS environments. A dedicated server requires at least 8 CPU cores and 24 GB of RAM; the developers recommend 16 or more cores and at least 32 GB for an optimal experience. The interface requires authentication, with TLS-encrypted local basic authentication, LDAP, and Keycloak options. Malcolm is self-hosted and free under the Apache License 2.0.
