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 examiners and incident responders who need to parse NTFS artifacts programmatically will find python-ntfs invaluable for building custom analysis pipelines that commercial tools can't accommodate. The 82 GitHub stars reflect active use in real investigations, and the library's direct parsing approach means you're not locked into a vendor's interpretation of the filesystem. Skip this if your team needs a turnkey GUI or NIST Respond capabilities like automated recovery workflows; python-ntfs is a building block for engineers, not an end-user platform.
