CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise red teams running structured adversary emulation programs should pick Core Security Cobalt Strike for its Malleable C2 profiles, which let you authentically simulate APT tradecraft without building custom infrastructure from scratch. The Arsenal Kit's Sleep Mask and reflective loader customizations give you the payload flexibility needed to stay ahead of defensive signatures in mature environments. Skip this if your team lacks the operator experience to tune these features; Cobalt Strike demands thoughtful configuration, not point-and-click execution.
Red teamers who need to validate their organization's incident response maturity should use Forensia to safely test detection gaps without expensive commercial tools. The free pricing and active GitHub community (785 stars) make it accessible for teams running regular adversary simulation exercises, and it directly exercises NIST Respond capabilities by forcing SOCs to detect and react to actual anti-forensics techniques rather than theoretical ones. Skip this if your goal is operational security for real engagements; Forensia is a training and validation tool, not tradecraft for active operations.
