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.
Forensic investigators and incident responders who need to reconstruct Windows application execution timelines will find AppCompatProcessor invaluable; it extracts AmCache and AppCompat registry artifacts that most commercial DFIR suites either miss or charge extra for. The tool is free and openly audited on GitHub with 209 stars, meaning you can validate the parsing logic yourself before deploying it at scale. Skip this if your team lacks Windows registry forensics expertise or if you need a GUI; AppCompatProcessor is command-line only and rewards practitioners who already read registry hives for a living.
