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 handling seized Apple devices need DMG2IMG to convert proprietary DMG archives into mountable HFS+ images without proprietary tools; the tool supports all three major compression formats (zlib, bzip2, LZFSE) and costs nothing, making it indispensable for chain-of-custody workflows. With 255 GitHub stars and active maintenance, it's proven in real investigations where you can't wait for commercial licensing. Skip this if your team exclusively uses commercial forensic suites like Cellebrite or Axiom that handle DMG conversion natively; DMG2IMG shines when you need a standalone, auditable converter that doesn't lock you into a vendor ecosystem.
Incident response teams and forensic investigators handling iOS devices or encrypted endpoints need FTK Imager Pro for its logical collection capability, which pulls messages, photos, and app data without full disk imaging, cutting acquisition time significantly. The tool's BitLocker detection and decryption paired with write-blocking covers NIST RS.AN and ID.RA requirements for evidence integrity and faster analysis cycles. Skip this if your primary need is network-layer incident detection or you lack dedicated forensics staff; FTK Imager Pro demands hands-on operator expertise and fits workflows where disk acquisition and mobile extraction are blocking your investigation timeline.
