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.
Threat analysts and incident responders who spend hours writing and debugging YARA rules will appreciate vim-yara for one reason: it catches syntax errors before you deploy a malformed rule to production. The plugin adds real-time error highlighting and auto-indenting directly in Vim, eliminating the friction of switching between your editor and a separate rule validator. Skip this if you're not a Vim user or if your team standardizes on other IDEs; a 14-star GitHub project signals this is built by and for the Vim-fluent minority, not a broad audience.
