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 and malware analysts who need to integrate Yara rule scanning into existing detection pipelines should use YaraScanner; it's a lightweight microservice that solves the specific problem of file scanning without forcing you into a vendor lock-in stack. The free pricing and 25 GitHub stars signal active maintenance from practitioners who understand forensic workflows. Skip this if your team lacks infrastructure to deploy and manage a standalone service or needs a UI-driven appliance for less technical analysts.
