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.
Malware analysts and incident responders who need fast, accurate PE header parsing will find PEview indispensable; it's the standard reference tool for understanding executable structure without spinning up a full sandbox or disassembler. It's free, lightweight, and has been the de facto utility for this task across Windows forensics for two decades. Skip this if you need dynamic behavior analysis or automated malware classification; PEview is static inspection only and won't tell you what a file actually does.
