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 examiners and incident response teams doing bare-metal or VM imaging need dc3dd for one reason: it adds cryptographic verification to dd without requiring a full commercial forensics suite. The tool computes MD5 and SHA hashes during acquisition, eliminating the separate hashing step that introduces chain-of-custody risk. Skip this if your team already owns EnCase or FTK; dc3dd solves a specific problem for shops that can't justify those licenses or need a lightweight acquisition layer in automated incident workflows.
