# About WELA
**WELA (Windows Event Log Analyzer, ゑ羅)** is a tool for auditing Windows event log settings.
Windows event logs are a vital source of information for Digital Forensics and Incident Response (DFIR), providing visibility into system activity and security events.
**Unfortunately, default configurations often lead to problems such as limited log retention, insufficient audit policies, and blind spots that reduce detection capability**.
WELA helps uncover these weaknesses and offers practical recommendations to improve audit settings and enhance security visibility.
WELA also assesses log configurations **based on real-world Sigma rule coverage**, allowing users to evaluate what can or cannot be detected under current the settings.
