AhnLab A-FIRST 디지털 포렌식 서비스 vs Zeek Analysis Tools (ZAT): Side-by-Side Comparison (2026)

AhnLab A-FIRST 디지털 포렌식 서비스

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.

Zeek Analysis Tools (ZAT)

Incident response teams already collecting Zeek network logs will extract real value from ZAT's Python-native ML pipeline; you get forensic analysis speed without building custom pandas and scikit-learn workflows from scratch. The 451 GitHub stars and active maintenance signal a tool that teams actually use post-breach, not one gathering dust. Skip this if you need a point-and-click UI or support for non-Zeek data sources; ZAT demands Python fluency and assumes your team is comfortable operationalizing machine learning models in incident workflows.
