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 responders and forensic analysts who need to reconstruct TCP sessions from live traffic or pcap files will find tcpick invaluable for its speed and precision in stream reassembly. The tool's text-mode interface and low resource overhead let you extract application-layer data without the GUI overhead of Wireshark, making it particularly effective in resource-constrained environments or when scripting large-scale packet analysis. Skip this if your team needs GUI-driven packet inspection or requires support for encrypted protocols like QUIC; tcpick excels at raw stream capture but won't decode modern transport-layer complexity.
