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 rapidly extract indicators from unknown binaries and archives will find Mastiff's modular plugin architecture faster than manual unpacking. The framework supports 185+ file types across Windows, Linux, and mobile formats, letting analysts process bulk samples without writing custom parsers. Skip this if you need GUI-driven workflows or automated triage at scale; Mastiff is CLI-first and requires scripting chops to operationalize at enterprise velocity.
