Decider is a self-hosted web application from CISA that helps network defenders, analysts, and researchers map adversary behaviors to the MITRE ATT&CK framework. It provides a guided question tree, powerful search and filtering, and export to formats like tables and ATT&CK Navigator heatmaps.

Use cases

  • map adversary behaviors to MITRE ATT&CK techniques
  • find the right ATT&CK tactic or subtechnique for observed activity
  • search and filter ATT&CK techniques during threat analysis
  • export ATT&CK mappings to Navigator heatmaps
  • walk junior analysts through ATT&CK mapping with guided questions

When to choose

  • you need to map adversary TTPs to ATT&CK accurately and quickly
  • you want a guided question tree instead of browsing the ATT&CK site manually
  • you need to export mappings as tables or ATT&CK Navigator layers
  • you want a login-less, self-hosted ATT&CK mapping tool

When to avoid

  • you only need to browse the official ATT&CK website without guided mapping
  • you need automated detection or threat intelligence feeds rather than manual mapping
  • you cannot run Docker or a self-hosted web application
