CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Forensic investigators and incident responders hunting for exfiltrated data will find Steghide essential for detecting steganographic payloads hidden in images and audio files; it's one of the few open-source tools that actually reverses the encoding process across both media types. The tool has been actively maintained for two decades and remains the reference implementation for LSB (least significant bit) steganography analysis. Skip this if your team needs GUI simplicity or enterprise support; Steghide requires command-line fluency and offers no vendor backing, making it a specialist's tool rather than a first-line detection platform.
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.
