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 reconstruct attacker behavior from network captures will find replayproxy invaluable for its ability to replay HTTP sessions directly from pcap files without manual extraction. The tool's lightweight design and zero-cost entry point make it practical for resource-constrained SOCs running ad-hoc investigations. Skip this if you need production-grade proxying or support for encrypted protocols; replayproxy solves a narrow forensic use case, not general proxy infrastructure.
