What is EZFile?

- SSN masking: Full SSNs are never stored or displayed. Only the last 4 digits are shown.
- Network blocking: Hooks prevent any network commands (curl, wget, etc.) from running.
- PII protection: Hooks block SSN/EIN patterns from appearing in web searches.
- Output scanning: Written files are scanned for accidentally exposed SSNs.
