CST VerdictBased on our analysis of available product data, here is our conclusion:
Incident response teams who need to pull forensic artifacts from Windows machines before an attacker covers their tracks should start with FastIR Collector; it's free, lightweight enough to run on suspect systems without heavy agent deployment, and built specifically for live acquisition rather than post-mortem analysis. The 519 GitHub stars and active maintenance signal real adoption among practitioners doing hands-on IR work. Skip this if your team needs cross-platform coverage or automated collection at scale; FastIR is a manual pull tool for Windows boxes, not a deployed sensor strategy.
Incident responders and forensic examiners who need scripted, repeatable evidence collection from compromised systems will find ir-rescue's volatility-aware approach saves hours during triage. The tool respects data decay by collecting RAM and process state before touching disk artifacts, which matters when you're working against the clock on live systems. Skip it if your team needs centralized case management, automated analysis, or integration with commercial SIEM platforms; ir-rescue is a collection engine, not an investigation platform.
