RedELK
RedELK is a SIEM platform purpose-built for red teams to centralize operational logs from multiple team servers and traffic logs from redirectors. It enables red team operators to search historical activities, detect blue team investigations, and manage long-term multi-server operations from a single dashboard.

What RedELK is
RedELK is a Python-based log aggregation and enrichment platform built on the Elastic Stack (Elasticsearch, Kibana, Logstash). It collects, correlates, and visualizes operational data and network traffic logs to support red team situational awareness and threat detection against defensive activities.

Best use cases
Implementation considerations
- Requires Docker and Docker Compose or manual Elasticsearch/Kibana/Logstash stack deployment; review wiki and maintained Ansible playbooks for guidance.
- Team server and redirector log parsers must be configured to forward logs; compatibility with your red team infrastructure (Cobalt Strike, Empire, etc.) should be verified before deployment.
- Latest stable release is v2.0.0-beta.6 (Feb 2022); confirm beta stability and any breaking changes relative to your operational timeline.
- Elasticsearch storage and performance planning needed; multi-month operations with high log volume may require indexed retention policies and cluster tuning.
- Access control and network isolation critical; RedELK aggregates sensitive operational data and should be isolated from untrusted networks.
When to avoid it — and what to weigh
- Blue Team / Defensive SOC Operations — RedELK is explicitly designed for red team offense. It is not a general-purpose enterprise SIEM and lacks the detection logic, compliance reporting, and incident response workflows expected by blue teams.
- Unauthorized Testing or Illegal Activity — RedELK is a tool for authorized security testing and red team exercises. Use outside authorized scope or legal frameworks exposes operator and organization to legal liability.
- Minimal Operational Logging Requirements — If your red team does not require multi-server log correlation, historical search, or blue team detection capabilities, the deployment complexity and infrastructure overhead may outweigh the benefit.
- No In-House Elasticsearch Expertise — RedELK depends on Elasticsearch, Kibana, and Logstash operations. Organizations without ELK Stack experience or dedicated infrastructure support will face steeper learning curves and operational risk.
License & commercial use

BSD 3-Clause is a permissive OSI license that permits commercial use provided attribution is maintained and the disclaimer is included. However, commercial deployment should confirm that underlying Elastic Stack dependencies (Elasticsearch, Kibana, Logstash) are also commercially compatible. Consult legal counsel if incorporating RedELK into a commercial service offering.

RedELK centralizes sensitive red team operational data (logs, screenshots, keystrokes, IOCs); network isolation and access control are critical. Elasticsearch and Kibana should be deployed on restricted networks with strong authentication. Ensure log forwarding between team servers and RedELK is encrypted and authenticated. No formal security audit, vulnerability disclosure policy, or hardening guide documented in README. Evaluate Elasticsearch/Kibana CVE history independently.
Alternatives to consider
Splunk
Enterprise SIEM with superior log ingestion, custom alerting, and compliance reporting; more expensive and not red-team-centric but offers broader operational use cases.
ELK Stack (vanilla)
Deploy Elasticsearch, Kibana, and Logstash directly without RedELK overlays; offers full flexibility but requires in-house log parsing, enrichment logic, and query development.
Graylog
Open-source log management platform with simpler deployment and lower resource overhead than Elasticsearch; less red-team-specific but suitable for general operational logging.
