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 analysts and incident responders who need to parse Windows event logs without commercial tools should reach for GrokEVT; it converts raw EVT files to readable formats fast enough to triage during active investigations. The tool is free and maintained on GitHub, removing licensing friction when you're building a lean forensics toolkit. Skip this if your team relies on GUI-driven analysis or needs to correlate events across multiple log sources in a single interface; GrokEVT is a command-line converter, not a log aggregation platform.
