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 security teams responding to suspected APT breaches need AhnLab A-FIRST 디지털 포렌식 서비스for its ability to reconstruct attack timelines and trace data exfiltration paths that most internal teams cannot execute alone. The service covers NIST RS.AN and RS.MI functions through root cause analysis and deleted data recovery, combining agent-based forensics with detailed remediation guidance. Skip this if your organization has mature incident response capabilities in-house or lacks the budget for hybrid managed forensics; A-FIRST is designed as a surge capacity service, not a replacement for a dedicated IR team.
Forensic investigators and incident responders who need to parse QCOW disk images without touching the host filesystem will find libqcow indispensable; it's the only read-only parser that handles multiple QCOW versions and compression formats in a single library. The tool has been in active development across cloud forensics workflows where QEMU-based infrastructure dominates, and its GitHub presence reflects genuine adoption in labs processing virtual machine evidence. Skip this if you need write capability or GUI-based triage; libqcow is strictly a programmatic library for analysts comfortable integrating it into Python or C workflows.
