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.
.NET security teams and malware analysts doing incident response need dnSpy because it's the only free tool that lets you step through compiled .NET code in real time without decompiling to source first, catching obfuscated payloads and anti-analysis tricks that static tools miss. The 29,000+ GitHub stars reflect actual adoption by red teamers and blue teamers alike, not theoretical appeal. Skip this if your threat model is primarily native binaries or you need GUI-based team collaboration; dnSpy is fundamentally a solo analyst's reverse-engineering workbench.
