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.
Forensics investigators and malware analysts who need to reverse-engineer proprietary binary formats without writing custom parsers should reach for Kaitai Struct. A single declarative schema compiles into working parsers across Python, C++, Java, and seven other languages, cutting weeks of manual parsing work to hours. Skip this if your team lacks developers comfortable with domain-specific languages or if you need a GUI-driven point-and-click tool; Kaitai requires code literacy and integrates into workflows, not replaces them.
