SELKS™ is a free, open-source, and turn-key Suricata network intrusion detection/protection system (IDS/IPS), network security monitoring (NSM) and threat hunting implementation created and maintained by Stamus Networks.


Released under GPL 3.0-or-later license, the live distribution is available as either a live and installable Debian-based ISO or via Docker compose on any Linux operating system.

Why is it called SELKS?

SELKS is comprised of the following major components:



What is Stamus Community Edition?

Stamus CE is the Stamus Networks open-source application that brings all these components together. Stamus CE provides the web interface for the entire system, giving you the ability to:



  • Manage multiple Suricata rulesets and threat intelligence sources 
  • Upload and manage custom Suricata rules and IoC data files 
  • Hunt for threats using predefined filters and enhanced contextual views
  • Apply thresholding and suppression to limit verbosity of noisy alerts
  • View Suricata performance statistics and information about Suricata rule activity
  • Apply Kibana, EveBox, and Cyberchef to the Suricata NSM and alert data

Who is SELKS for?

For many small-to-medium sized organizations, SELKS can be a suitable production-grade network security monitoring (NSM) and intrusion detection (IDS) solution.

And because all the data available in SELKS is generated by the Suricata engine, SELKS is widely used by network security practitioners, researchers, educators, students, and hobbyists to explore what is possible with Suricata IDS/IPS/NSM and the network protocol monitoring logs and alerts it produces. 


For enterprise scale applications, please review our commercial solution, Stamus Security Platform (SSP), described below.


Download SELKS

SELKS Docker Compose Package

Use the Docker Compose package to install SELKS in any LINUX environment and ensure you are including the very latest containers, including Evebox and Suricata.


Get SELKS on Docker

Complete Image with Desktop

Use the image with Desktop when you want a turnkey installation that includes the Debian x64 12 (Bookworm) Linux desktop environment. Can be deployed on bare metal hardware or VM.


SELKS 10 ISO with Desktop

Complete Image without Desktop

Use the image without Desktop when you want a turnkey SELKS installation in a headless environment (based on Debian x64 12 Bookworm). Can be deployed on bare metal hardware or VM.

What About Enterprise Scale Deployments?

While SELKS is a great system to test out the power of Suricata for intrusion detection and threat hunting, it was never designed to be deployed in an enterprise setting. For enterprise applications, please review our commercial solution, Stamus Security Platform.

What is Stamus Security Platform™?

Stamus Security Platform (SSP) is the commercial network-based threat detection and response solution from Stamus Networks.


NOTE: While it retains much of the same look and feel as SELKS, SSP is a completely different system and requires a new software installation.


Available in two license tiers, SSP delivers:


Broad-Spectrum Threat Detection

  • Multiple detection mechanisms including machine learning, anomaly detection, signatures, and IoC matching
  • High-fidelity Declarations of Compromise with multi-stage attack timeline
  • Weekly threat intelligence updates from Stamus Labs
  • Easy integration of third party rulesets and threat intelligence


Guided Threat Hunting and Incident Investigation

  • Advanced guided threat hunting filters
  • Host insights tracks over 60 security-related attributes
  • Easily convert hunt results into custom detection logic
  • Explainable and transparent results with evidence


Enterprise Scale Management and Integration

  • Automated classification and alert triage
  • Management of multiple probes from single console
  • Seamless integration with SOAR, SEIM, XDR, EDR, IR
  • Multi-tenant operation
  • Configuration backup and restoration

See the table below for a summary comparison between SELKS and the Stamus Networks commercial offerings.


NOTE: While it retains much of the same look and feel as SELKS, SSP is a completely different system and requires a new software installation.
