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 ingests and analyzes network security artifacts like PCAP files, Zeek logs, and Suricata alerts. It automatically normalizes, enriches, and correlates this data to provide comprehensive visibility into network communications for security monitoring and incident response. The tool is designed to be easily deployable across various environments, from security operations centers to individual laptops.
Security analysts, incident responders, and network security teams in organizations needing to monitor and investigate network traffic for threats, particularly those in industrial control systems (ICS) environments.
Developers choose Malcolm because it integrates multiple powerful open-source tools into a single, cohesive suite with a streamlined containerized deployment, avoiding the cost and complexity of proprietary solutions while offering robust analysis capabilities and secure communications.
Malcolm is a powerful, easily deployable network traffic analysis tool suite for full packet capture artifacts (PCAP files), Zeek logs and Suricata alerts.

Supports browser-based PCAP uploads and lightweight forwarders for live capture, simplifying data input as highlighted in the README.
Integrates OpenSearch Dashboards for visualization and Arkime for session investigation, providing a unified interface for deep traffic analysis.
Containerized setup enables quick deployment on various platforms from servers to laptops, making it portable for different use cases.
Uses industry-standard encryption for all user and forwarder communications, ensuring data security as per the README.
The cluster of containers demands significant CPU and memory, which can be prohibitive for low-spec or budget-constrained environments.
Requires configuration and tuning of multiple integrated tools like OpenSearch and Arkime, posing a steep learning curve for new users.
ICS protocol parsers are noted as 'ongoing development' in the README, limiting immediate readiness for specialized industrial networks.
