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.
