CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams that need to move fast on active incidents will find AISI DFIR's managed service model cuts through the hiring shortage for in-house forensics expertise. The Scout and Hunter tools automate evidence collection and persistence removal directly on affected systems, compressing response timelines that would otherwise stretch weeks. The caveat: this is a managed service first, so your team trades hands-on control for speed and specialist depth, making it less suitable for organizations that need full visibility and control over every forensic decision.
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.
