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.
ELAT (Event Log Analysis Tool)
Incident responders and forensic analysts investigating Windows systems will find immediate value in ELAT for parsing event logs that commercial tools often obscure behind expensive licensing. The tool is free, open source with 29 GitHub stars, and handles the tedious log correlation work that consumes hours in manual triage. Skip this if your team needs real-time alerting or cross-platform visibility; ELAT is a forensic workbench for post-incident analysis, not a detection engine.
