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 forensics teams working Windows environments will find Meerkat valuable for fast endpoint triage when you need to gather artifacts without deploying heavy agents. The 480 GitHub stars and active community contributions signal it's battle-tested by practitioners who need quick PowerShell-based reconnaissance. Skip this if your team lacks PowerShell expertise or needs GUI-driven workflows; Meerkat demands scripting comfort and assumes you're doing manual collection rather than orchestrated response automation.
