Based 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 hunting teams and incident responders who need to process thousands of files daily without licensing friction should deploy Strelka; its container-based architecture scales file extraction and metadata collection across enterprise infrastructure while remaining free. The tool ingests files at real-time speed and performs deep inspection through modular workers, making it particularly effective for hunting campaigns that require bulk file triage before analyst review. Skip this if your team needs automated response actions or SOAR integration; Strelka is a detection and hunting platform, not an orchestration tool.
