A powerful, easily deployable network traffic analysis tool suite for PCAP files, Zeek logs, and Suricata alerts.
Malcolm is a network traffic analysis tool suite that processes full packet capture (PCAP) files, Zeek logs, and Suricata alerts for security monitoring. It automatically normalizes, enriches, and correlates network data to provide comprehensive visibility into network communications and security incidents. The tool is designed to be easily deployable across various environments, from security operations centers to individual incident response engagements.
Security analysts, incident responders, and network administrators in SOCs or industrial control systems environments who need to analyze network traffic for threats and anomalies. It's also suitable for individual security professionals conducting investigations on portable setups like laptops.
Developers choose Malcolm because it integrates multiple powerful open-source tools (like OpenSearch and Arkime) into a cohesive, containerized framework that is easier to deploy and manage than assembling components manually. Its focus on industrial control systems protocols and permissive Apache 2.0 license make it an attractive alternative to proprietary security solutions.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Runs as a cluster of Docker containers, enabling quick setup on various platforms from servers to laptops, as highlighted in the README for streamlined deployment.
Integrates OpenSearch Dashboards for visualization and Arkime for deep session inspection, providing powerful, prebuilt tools for network traffic analysis.
Includes ongoing development for parsers targeting industrial control systems protocols, enhancing visibility in specialized environments beyond general network monitoring.
All communications use industry-standard encryption for uploading PCAP files and live capture via lightweight forwarders, ensuring secure data handling.
Requires Docker and container management skills, which can be a barrier for users unfamiliar with containerized environments, despite the simplified scripts.
Running multiple containers may demand significant system resources (e.g., RAM and CPU), making it less suitable for low-spec hardware or lightweight deployments.
Primarily handles PCAP, Zeek, and Suricata logs, so it's not a general-purpose SIEM for endpoint logs or other non-network security data sources.
