- HR and onboarding files for international staff
- Travel bookings and expense documentation
- KYC and identity-verification paperwork
- Scanned passport copies in Downloads or shared drives
How FileSentinel handles it
Built-in detection, scored and local
FileSentinel reads inside your files on your own machine, flags passport numbers with a confidence and severity score, and helps you remediate. Built-in detectors cover the common cases, and a custom rule builder lets you add plain-text or regex detectors for anything specific to your work.
Score
Every finding gets a confidence and severity score, so real passport numbers rise above coincidental matches.
OCR
With OCR on, FileSentinel reads text inside images and scanned PDFs, catching passport numbers in screenshots and scans.
Remediate
Redact values, mark false positives, or export a CSV, HTML, or PDF report, then share with confidence.
Private by design
Your files never leave your PC
Scanning, OCR, and remediation all happen on-device. FileSentinel makes no network connections to do its work, so the very data you are trying to protect never has to leave your machine to be checked. No server, no cloud, no upload step.
