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 responders and forensic analysts working Windows environments will get immediate value from LastActivityView for timeline reconstruction during active investigations; it pulls user logons, process execution, file access, and registry changes into a single sortable view that cuts hours off manual event log parsing. The tool is free and requires no installation or agent, meaning you can run it on compromised systems without leaving forensic footprints or touching your EDR licensing. Skip this if you need continuous monitoring or alerting; LastActivityView is a forensic scraper, not a detection engine, and it only surfaces activity after the fact.
