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.
Incident response teams doing manual malware analysis or memory forensics on a tight budget should start with CIRTKit; it bundles packet analysis, memory dumps, and automation into one console built on Viper, eliminating the friction of stringing together five separate tools. The 150 GitHub stars and active framework integration show this isn't abandoned ware, and free pricing means zero procurement friction for labs or smaller SOCs. Skip this if your incident response is mostly alert triage and containment; CIRTKit assumes you're spending hours in artifacts, not minutes closing tickets.
