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 response teams without deep graph database expertise will find Beagle's free, open-source approach to log correlation unusually practical; it transforms raw security data into attack timelines without requiring you to learn Splunk syntax or pay per-gigabyte licensing. The 1,322 GitHub stars and active maintenance signal a community that's stress-tested this against real incidents. Skip Beagle if your team needs a turnkey UI with role-based access controls or if you're standardized on commercial SIEM; it's a practitioner's tool that rewards those willing to write queries and maintain their own infrastructure.
