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 extract evidence from Windows systems will find libesedb invaluable; it's one of the few tools that can reliably parse ESE databases left behind by Search, Exchange, and Active Directory without requiring the original application or Windows installation. The library has 371 GitHub stars and is actively maintained by the open source community, making it a proven choice in thousands of real investigations. Skip this if your team lacks forensic expertise or needs a GUI; libesedb is a command-line parser for analysts who already know what they're looking for in a database dump.
