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.
Java incident responders and forensic analysts who need to reverse-engineer compiled bytecode will find CFR invaluable; it handles modern Java features up to version 14 that older decompilers choke on, giving you readable source from binaries without guesswork. The tool is free and requires no licensing overhead, making it easy to drop into any malware analysis or post-breach code review workflow. Skip this if your team primarily targets legacy Java 6-8 applications or needs a GUI; CFR is command-line only and optimized for current language syntax.
