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.
Organizations that have already been hit by ransomware need No More Ransom to check whether a decryption key exists for their variant before paying; the tool's database covers over 150 known ransomware families with working decryptors, saving time in the critical hours after discovery. The project is maintained by Interpol, the Dutch National Police, and major security vendors, which means the decryption keys are legitimate and the malware identifications are accurate. This is a reactive tool, not prevention, so it won't help teams that need to stop ransomware before encryption happens; those teams should focus spending elsewhere first.
