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.
Windows incident responders who need fast triage on a budget should start with IRTriage; it automates evidence collection across a fleet without requiring agent deployment or licensing overhead. The tool is genuinely free with active GitHub maintenance (138 stars, recent commits), which means no procurement cycle for your first incident or your hundredth. Skip this if your team primarily investigates cloud infrastructure or non-Windows environments; IRTriage solves a specific problem on a specific OS and doesn't pretend otherwise.
