Aurora Incident Response vs Incident Response Investigation System (IRIS): 2026 Comparison

Aurora Incident Response

Small incident response teams and solo practitioners who need to track findings and tasks during investigations will get the most from Aurora Incident Response, especially because it's free and requires no infrastructure investment to get started. The tool has 1,062 GitHub stars and solves the core documentation problem: keeping forensic findings and remediation tasks in one place instead of scattered across spreadsheets and Slack. Skip this if you need automated evidence collection, timeline reconstruction, or integration with your SIEM; Aurora is documentation-first, not collection-first.

Incident Response Investigation System (IRIS)

Security teams running lean IR operations with limited budget will get the most from Incident Response Investigation System (IRIS); it cuts investigation friction by letting responders collaborate on timelines and artifacts in a shared workspace without the licensing cost of commercial platforms. The Docker-native deployment means you're live in hours, not weeks of procurement and integration, and the 1,444 GitHub stars signal actual adoption among practitioners who've validated the interface. Skip IRIS if your team relies on automated playbook execution or needs tight integration with your existing SOAR; this is investigation coordination, not orchestration.
