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 exotic file systems and storage formats without touching original media should build dfvfs into their toolkit. The tool handles 40+ file systems and image formats natively, making it invaluable when you're working with seized devices, cloud snapshots, or proprietary storage layouts that commercial forensic suites charge premium licensing for. Free and open source means you can audit the code and deploy it at scale without per-seat costs. Not the fit if you need a turnkey GUI or automated artifact parsing; dfvfs is a library for practitioners who write scripts, not a packaged investigation platform.
