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 that need to triage and correlate alerts without expensive commercial tools should evaluate Request Tracker for Incident Response; its ticketing workflow reduces noise by letting analysts link related reports and track investigation status in one place. RTIR ships free and has been deployed at scale in academic and government environments for over a decade, meaning the operational stability is proven. Skip this if your team expects a polished UI or built-in threat intelligence feeds; RTIR rewards operators willing to customize and integrate it into existing toolchains.
