CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Incident responders working offline or in air-gapped environments need Spyre because it runs as a standalone binary with zero dependencies, letting you scan for IOCs on any host without network callbacks or agent deployment. The tool ships modular, so you load only the checks you need, and at 176 GitHub stars it has real adoption among practitioners who value simplicity over feature bloat. Skip this if you're looking for continuous monitoring or behavioral detection; Spyre is a manual scanner for triage, not a persistent hunting platform.
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.
