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.
Forensic analysts and incident responders who need to extract and replay live traffic from pcap files will find Chaosreader invaluable; it carves out files and reconstructs protocols that commercial tools often miss or charge heavily for. The tool is free and has a stable 239 GitHub stars with active forensic community adoption. Skip this if you're looking for automated threat hunting or real-time network monitoring; Chaosreader is a manual extraction utility best suited to post-breach analysis, not prevention.
