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.
Forensic analysts and incident responders investigating suspected data exfiltration will find WavSteg useful for understanding steganographic attack chains; it's one of the few free tools that actually demonstrates LSB encoding in audio files rather than just documenting the technique. The 15 GitHub stars and active C implementation mean you get working code you can audit and modify for custom forensic workflows. Skip this if you need detection or prevention capabilities; WavSteg is purely for post-incident analysis of how attackers hide payloads, not for stopping them in motion.
