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 teams investigating data exfiltration and insider risk will find real value in Cognni Incident Investigation because it traces file movement and user behavior across your entire environment, not just flagging alerts but showing you what actually left and where. The tool maps NIST RS.AN (Incident Analysis) and RS.MI (Incident Mitigation) directly into workflows that identify compromised users, locate exposed files, and guide permission lockdown in a single investigation thread. Skip this if you need endpoint detection or threat hunting; Cognni assumes your security alerts already exist upstream and focuses purely on rapid forensic closure and remediation.
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.
