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 rapidly extract files from pcap data without parsing every packet manually should reach for tcpxtract; its file signature-based extraction handles dozens of formats at scale and runs on minimal hardware. The tool's free, open-source design means you can deploy it in airgapped networks or integrate it into automated triage pipelines without licensing friction. Skip this if you need GUI-driven workflows or post-extraction file analysis; tcpxtract stops at extraction and leaves validation to your other tools.
