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 without budget for commercial EDR will get the most from GRR Rapid Response, a free framework that performs memory acquisition and artifact analysis on live Windows systems faster than manual approaches. The 5,047 GitHub stars and active community mean you're not betting on abandoned code. Skip this if your team needs GUI-driven workflows or cross-platform support; GRR is Python-based CLI work, and it prioritizes forensic depth over ease of use.
